A Case of Noncompaction at All Segments of Both Right and Left Ventricles Wed, 26 Nov 2014 11:44:45 +0000 http://www.hindawi.com/journals/cric/2014/325257/ Background. Noncompaction/hypertrabeculation left ventricle (NCM/HVM) is most commonly reported in one or more segments of left ventricle and sometimes both ventricles. In this case, we present noncompaction of all segments of right and left ventricle, in a young man with mental retardation. Case Presentation. A 19-year-old male was referred to us with sudden dyspnea at rest and chest discomfort. He was a known case of mental retardation. He was born full term with birth weight = 1250 grams. On physical examination. A systolic murmur (II/VI) at left sternal border was heard. ECG showed increased voltage in precordial lead and deep ST segment depression. Chest X-ray (CXR) was within normal limits. Transthoracic echocardiography showed situs solitus, D loop, normal connection of great vessels, noncompaction LV at all segments (noncompaction/compaction = 2.5/0.5) with moderate systolic dysfunction (LVEF = 40%), diastolic dysfunction grade II, normal RV size with mild systolic dysfunction and hypertrabeculation, mild tricuspid regurgitation (TR), and normal pulmonary artery systolic pressure. After injection of agitated saline some bubbles were passed from right to left through patent foramen oval (PFO). Conclusions. Extensive sinusoid formation and trabeculation of RV and nearby all LV segments and its association with mental retardation suggest presence of strong genetic background.

Cheating the CHA2DS2-VASc Score: Thromboembolism in Apical Hypertrophic Cardiomyopathy Thu, 20 Nov 2014 11:34:03 +0000 http://www.hindawi.com/journals/cric/2014/189895/ Atrial fibrillation increases the risk of systemic thromboembolism in general and stroke in particular. Not all patients who develop atrial fibrillation are at significantly heightened risk of thromboembolic complications, however, with the development of risk scoring systems aiding clinicians in determining whether formal anticoagulation is mandated. The most commonly used contemporary scoring systems—CHADS2 and CHA2DS2-VASc—provide a reliable means of assessing stroke risk, but certain cardiac conditions are associated with an increased incidence of thromboembolism without impacting on these risk scores. Hypertrophic cardiomyopathy, with its apical variant, is such a condition. We present a case of a patient with apical hypertrophic cardiomyopathy and atrial fibrillation who suffered dire thromboembolic consequences despite a reassuringly low CHA2DS2-VASc score and suggest that this scoring system is modified to incorporate the thromboembolic risk inherent to certain cardiomyopathies irrespective of impairment of left ventricular systolic dysfunction or clinical heart failure.

An Extremely Rare Reason for Failure of Left Sided Pacemaker Implantation Wed, 19 Nov 2014 00:00:00 +0000 http://www.hindawi.com/journals/cric/2014/453071/ We reported a case of isolated anomaly of the left brachiocephalic vein which is diagnosed during a permanent pacemaker implantation. It is a very rare anomaly and makes the left sided pacemaker implantation impossible. Erdem Özel, Ali Öztürk, Emin Evren Özcan, and Berhan Genç Copyright © 2014 Erdem Özel et al. All rights reserved. Coronary Artery Fistulae Discovered during Presentation of a Patient Having Heart Failure due to Severe Aortic Stenosis Sun, 16 Nov 2014 00:00:00 +0000 http://www.hindawi.com/journals/cric/2014/213673/ Introduction. Coronary artery fistulae (CAF) are rare defects with abnormal communication between a coronary artery with either a cardiac chamber or another vascular structure, bypassing the myocardial capillary network. We report a rare multiple arterial coronary fistulae with drainage to the right pulmonary artery. Case Presentation. A 56-year-old male was brought to our hospital for work-up of severe aortic stenosis. Further evaluation revealed multiple CAF with abnormal drainage to the right pulmonary artery. He was discharged after aortic valve replacement and closure of the coronary fistula. Conclusion. This case demonstrates that patients with complex CAF and drainage to the right pulmonary artery can remain asymptomatic and diagnosed accidentally during cardiac imaging, presenting particular challenges in both medical and surgical treatment.

An Unusual Presentation of a Myocardial Crypt in Hypertrophic Cardiomyopathy Wed, 12 Nov 2014 11:51:02 +0000 http://www.hindawi.com/journals/cric/2014/737052/ Hypertrophic cardiomyopathy (HCM) is a common inherited cardiovascular disease with prevalence of 0.2% in the population. More than 1000 mutations in more than 10 genes encoding for proteins of the cardiac sarcomere have been identified. Cardiac magnetic resonance imaging (CMR) is used to characterize left ventricular morphology with great precision in patients with HCM and it identifies unique structural abnormalities in patients with HCM. We present a case of a 56-year-old man who had positive family history of HCM who was a carrier of the genetic MYH-7 2770 G > C, exon 23 mutation. Transthoracic echocardiography showed thickening of the interventricular septum (16 mm) and in particular the basal septum. CMR confirmed the diagnosis of HCM in the anteroseptal myocardium with a thickness of 23 mm and also revealed large and deep myocardial crypts in the anterior wall. These myocardial crypts are rarely found in the so-called genotype positive and phenotype positive patients, as in our case. Also the crypts in this case are deeper and wider than those reported in other cases. So in conclusion, this case reveals an uncommon finding of a myocardial crypt at an unusual myocardial site with the unusual morphology in a patient with genotypic and phenotypic expression of hypertrophic cardiomyopathy.

Asymptomatic Late Migration of an Atrial Pacemaker Lead into the Right Lung Wed, 12 Nov 2014 07:00:44 +0000 http://www.hindawi.com/journals/cric/2014/145917/ This report illustrates an unusual case of asymptomatic late cardiac perforation by an atrial pacemaker lead into the right lung. In the present case, the lead was explanted by simple manual traction through the device pocket without any complications. Nicolas De Schryver, Sebastien Marchandise, Geoffrey C.

Aortic Balloon Valvuloplasty Prior to Orthotopic Liver Transplantation: A Novel Approach to Aortic Stenosis and End-Stage Liver Disease Sun, 09 Nov 2014 11:36:20 +0000 http://www.hindawi.com/journals/cric/2014/325136/ The combination of severe aortic stenosis and end-stage liver disease increases the morbidity and mortality of surgical aortic valve replacement or orthotopic liver transplantation resulting in a prohibitive operative risk. We propose a staged approach of balloon aortic valvuloplasty prior to orthotopic liver transplantation as a bridge to definitive aortic valve replacement. Between 2010 and 2012, four patients with severe aortic stenosis and end-stage liver disease underwent staged balloon aortic valvuloplasty followed by orthotopic liver transplantation. All patients had been deemed to be inappropriate candidates for liver transplantation or aortic valve surgery due to their comorbidity. One patient died of complications from a perivalvular abscess. Three patients went on to successful graft implantation and function and surgical recovery. Two of the three patients proceeded to definitive surgical aortic valve replacement with the remainder currently undergoing evaluation. In this case series, we present a novel approach of balloon aortic valvuloplasty prior to liver transplantation as a potential bridge to definitive treatment of severe aortic stenosis in the end-stage liver patient.

Late Presentation of Persistent Left Superior Caval Vein in a Univentricular Heart with Successful Transcutaneous Occlusion Using Cera Lifetech Atrial Septal Occluder Thu, 06 Nov 2014 11:40:08 +0000 http://www.hindawi.com/journals/cric/2014/383529/ We present a case of persistent left superior caval vein in a univentricular heart presenting with progressive and disabling cyanosis in a 35-year-old man eighteen years after his Kawashima operation. The vein was successfully occluded using an atrial septal occluder with significant improvement of symptoms and oxygen saturation.

A Case of Severe Carotid Stenosis in a Patient with Familial Hypercholesterolemia without Significant Coronary Artery Disease Thu, 23 Oct 2014 08:30:57 +0000 http://www.hindawi.com/journals/cric/2014/853921/ Familial hypercholesterolemia (FH) is an inherited metabolic disorder characterized by elevated low-density lipoprotein cholesterol levels in the blood. In its heterozygous form, it occurs in 1 in 500 individuals in the general population. It is an important contributor to the early onset of coronary artery disease (CAD), accounting for 5–10% of cases of cardiovascular events in people younger than 50 years. Atherogenesis triggered by hypercholesterolemia generally progresses faster in the coronary arteries, followed by the subsequent involvement of other arteries such as the carotids. Thus, symptoms of CAD commonly appear before the onset of significant carotid stenosis. Herein, we report the case of a patient with untreated FH who had severe carotid atherosclerosis at the age of 46 years but had no evidence of significant CAD.

Congenital long QT syndrome type 2 (LQTS2) is a rare inherited cardiac abnormality resulting in increased risk of polymorphic ventricular tachycardia (PVT). Case Description. A 21-year-old postpartum female presented with syncopal episode after phone alarm. She was noted to have PVT on telemetry monitoring in the emergency department. EKG revealed QTc of 530. The patient’s only medication was medroxyprogesterone. She ultimately received a dual chamber pacemaker with ICD. Discussion. LQTS2 is associated with alarm sounds as a precipitating factor. Postpartum hormonal shifts as well as medroxyprogesterone have significant effect on native QTc duration. John Kern, Margaret Duffy, Corinne Kern, and Victor Mazza Copyright © 2014 John Kern et al.

Traumatic Tension Pneumothorax as a Cause of ICD Failure: A Case Report and Review of the Literature Tue, 07 Oct 2014 14:00:59 +0000 http://www.hindawi.com/journals/cric/2014/261705/ Background. Tension pneumothorax can infrequently cause ventricular arrhythmias and increase the threshold of defibrillation. It should be suspected whenever there is difficulty in defibrillation for a ventricular arrhythmia. Purpose. To report a case of traumatic tension pneumothorax leading to ventricular tachycardia and causing defibrillator failure. Case. A 65-year-old African-American female was brought in to our emergency department complaining of dyspnea after being forced down by cops. She had history of mitral valve replacement for severe mitral regurgitation and biventricular implantable cardioverter defibrillator inserted for nonischemic cardiomyopathy. Shortly after arrival, she developed sustained ventricular tachycardia, causing repetitive unsuccessful ICD shocks. She was intubated and ventricular tachycardia resolved with amiodarone. Chest radiograph revealed large left sided tension pneumothorax which was promptly drained. The patient was treated for congestive heart failure; she was extubated on the third day of admission, and the chest tube was removed. Conclusion. Prompt recognition of tension pneumothorax is essential, by maintaining a high index of suspicion in patients with an increased defibrillation threshold causing ineffective defibrillations.

Potential Additive Effects of Ticagrelor, Ivabradine, and Carvedilol on Sinus Node Mon, 29 Sep 2014 00:00:00 +0000 http://www.hindawi.com/journals/cric/2014/932595/ A 51-year-old male patient presented to the emergency room with an anterior ST-elevation myocardial infarction. After a loading dose of both ticagrelor and aspirin, the patient underwent primary-PCI on the left anterior descending coronary artery with stent implantation. After successful revascularization, medical therapy included beta-blockers, statins, and angiotensin II receptor antagonists. Two days later, ivabradine was also administered in order to reduce heart rate at target, but the patient developed a severe symptomatic bradycardia and sinus arrest, even requiring administration of both atropine and adrenaline. Ivabradine and ticagrelor have been then suspended and this latter changed with prasugrel. Any other similar event was not reported during the following days. This clinical case raised concerns about the safety of the combination of beta-blockers and ivabradine in patients treated with ticagrelor, particularly during the acute phase of an acute coronary syndrome. These two latter drugs, in particular, might interact with the same receptor. In fact, ivabradine directly modulates the If-channel which is also modulated by the cyclic adenosine monophosphate levels. These latter have been shown to increase after ticagrelor assumption via inhibition of adenosine uptake by erythrocytes. Further studies are warrant to better clarify the safety of this association.

Phantom Tumor of the Lung: Localized Interlobar Effusion in Congestive Heart Failure Sun, 28 Sep 2014 09:05:05 +0000 http://www.hindawi.com/journals/cric/2014/207294/ Localized interlobar effusions in congestive heart failure (phantom or vanishing lung tumor/s) is/are uncommon but well known entities. An 83-year-old man presented with shortness of breath, swollen legs, and dry cough enduring five days. Chest-X-ray (CXR) revealed massive sharply demarked round/oval homogeneous dense shadow 10 × 7 cm in size in the right inferior lobe. The treatment with the loop diuretics and fluid intake reduction resulted in complete resolution of the observed round/oval tumor-like image on the control CXR three days later. Radiologic appearance of such a mass-like configuration in patients with congestive heart failure demands correction of the underlying heart condition before further diagnostic investigation is performed to avoid unnecessary, expensive, and possibly harmful diagnostic and treatment errors.

An Unusual Cause of Cardiac Tamponade during Cardiac Catheterization Study Thu, 18 Sep 2014 00:00:00 +0000 http://www.hindawi.com/journals/cric/2014/652592/ Introduction. Catheter-based diagnostic and therapeutic procedures are rapidly advancing. However, catheter related complications sometimes become life threatening. Cardiac tamponade is a rare but serious complication of this procedure. We have summarized one cardiac tamponade pejoration due to secondary coronary vessels laceration by the implanted pericardial drainage. Case report. A 4-year-old baby having Tetralogy of Fallot was posted for diagnostic catheterization study. Patient was induced with sevoflurane and spontaneous respiration was maintained. After catheter insertion to RV, dye was injected through the catheter which rapidly spread into the pericardial cavity indicating right ventricle perforation. Immediately, blood was aspirated under transthoracic echocardiographic guidance and hemodynamics started improving. For the provision of quick access to aspirate further collection, an intrapericardial sheath was inserted after multiple attempts. Patient’s condition started deteriorating again. TTE revealed again some collection and it was increasing gradually. On exploration, it was found that there was continuous bleeding from a lacerated epicardial vessel which contributed to the pericardial collection leading to further tamponade effect. This second iatrogenic injury complicated the management of the first iatrogenic cardiac perforation and, thereby, created a life-threatening situation which needed immediate surgical exploration. Discussion. Usual cause of tamponade after right ventricular perforation is bleeding from the RV, but in our case the second tamponade was not due to bleeding from the RV, but was rather from new laceration injury of epicardial vessels which was remained undiagnosed till exploration.

Oral Phenytoin Toxicity Causing Sinus Arrest: A Case Report Thu, 11 Sep 2014 09:00:14 +0000 http://www.hindawi.com/journals/cric/2014/851767/ We present a case of sinus node arrest leading to symptomatic junctional bradycardia from oral phenytoin toxicity, which is a rare presentation. Our patient had no prior cardiac history and was on phenytoin therapy for seizure disorder. Although bradycardia is more commonly associated with intravenous phenytoin and there were few case reports of bradycardia with oral phenytoin reported, the literature is limited. In this case report, we also reviewed the pathophysiology of phenytoin-induced cardiac toxicity. Ravi K. Thimmisetty, Janardhana Rao Gorthi, and Mahmoud Abu Hazeem Copyright © 2014 Ravi K.

Thrombus Formation on Amplatzer Septal Occluder Device: Pinning Down the Cause Tue, 02 Sep 2014 10:19:41 +0000 http://www.hindawi.com/journals/cric/2014/457850/ The use of interatrial septal occluder devices is an efficacious and less invasive alternative to open heart surgery for the repair of atrial septal defects. These devices present significant risks including thrombus formation on the device and subsequent thromboembolic events. We present a case of a woman who presented with stroke-like symptoms five years after PFO closure. The patient was subsequently found to have a thrombus on the occluder device. Our case highlights the risk of such thrombolic phenomenon and the risk associated with the device structure as a nidus for such a complication.

Rapidly Progressive Atrioventricular Block in a Patient with Sarcoidosis Thu, 21 Aug 2014 13:16:18 +0000 http://www.hindawi.com/journals/cric/2014/372936/ Cardiac sarcoidosis is a major cause of death in patients with systemic sarcoidosis. Cardiac manifestations are seen in 2.3% of the patients. Atrioventricular (AV) block is one of the common manifestations of cardiac sarcoidosis. Other presentations of cardiac involvement include congestive heart failure, ventricular arrhythmias, and sudden cardiac death. The presence of AV block in young patients should raise the suspicion of sarcoidosis. AV block may be the only manifestation and patients may not have clinical evidence of pulmonary involvement. Here we describe a young male presented with exercise induced AV block rapidly progressing to complete heart block with recurrent syncope needing urgent pacemaker implantation. Factors that suggested an infiltrative process included his young age, rapidly progressive conduction abnormalities in the ECG in the absence of coronary disease, and previous history of cutaneous sarcoidosis.

Total Anomalous Systemic Venous Drainage with Heterotaxia Syndrome: A Rare Case Tue, 12 Aug 2014 09:26:21 +0000 http://www.hindawi.com/journals/cric/2014/392841/ Total anomalous systemic venous return is a very rare anomaly, where vena cava inferior, vena cava superior, and coronary sinus drain into left atrium. Two-day-old male baby was admitted with cyanosis and tachypnea after the birth. Left atrial isomerism with anomalous systemic venous drainage was found on echocardiographic examination. We present an unusual case of total anomalous systemic venous drainage in to the left atrium.

A Case of Kawasaki Disease with Coronary Aneurysm Responding to the 4th IVIG Treatment Tue, 05 Aug 2014 00:00:00 +0000 http://www.hindawi.com/journals/cric/2014/821812/ Kawasaki disease is an acute febrile illness that usually occurs in children younger than 5 years of age. The use of intravenous immunoglobulin (IVIG) within the first 10 days of illness has been shown to reduce the incidence of coronary artery aneurysms significantly. The relative roles of repeated doses of intravenous immunoglobulin (IVIG) are controversial in refractory Kawasaki disease (KD). Most experts recommend the second retreatment with IVIG, 2 g/kg in refractory KD. However, the dose-response effect of the third or fourth IVIG was uncertain. Although there have been a significant number of reports on new therapeutic options for refractory KD, such as steroid, infliximab, methotrexate, and other immunosuppressants, their effectiveness in reducing the prevalence of coronary artery aneurysms was unproven. We present here KD patient with small coronary artery aneurysm who is resistant to the third IVIG and steroid pulse therapy but showed improvement immediately after the infusion of the 4th IVIG on fever day 18.

High-Risk Acute Coronary Syndrome in a Patient with Coronary Subclavian Steal Syndrome Secondary to Critical Subclavian Artery Stenosis Mon, 04 Aug 2014 11:32:53 +0000 http://www.hindawi.com/journals/cric/2014/175235/ Patients with multivessel coronary artery disease are more likely to have extensive atherosclerosis that involves other major arteries. Critical subclavian artery (SCA) stenosis can result in coronary subclavian steal syndrome that may present as recurrent ischemia and even myocardial infarction in patients with coronary artery bypass graft (CABG). In patients with concomitant severe native coronary disease, occluded saphenous venous grafts (SVG) to other arteries, percutaneous intervention on critical subclavian artery (SCA) stenosis that will compromise the blood flow to left internal mammary graft (LIMA) and left anterior descending (LAD) artery will be a high-risk procedure and may be associated with cardiogenic shock, especially in patients with preexisting ischemic cardiomyopathy. The use of percutaneous left ventricular (LV) assist device like Impella will offer better hemodynamic support and coronary perfusion and therefore results in decreased myocardial damage, maximized residual cardiac function, and lower incidence of cardiogenic shock.

Successful Venous Angioplasty of Superior Vena Cava Syndrome after Heart Transplantation Sun, 03 Aug 2014 11:19:06 +0000 http://www.hindawi.com/journals/cric/2014/490276/ Introduction. For patients with terminal heart failure, heart transplantation (HTX) has become an established therapy. Before transplantation there are many repeated measurements with a pulmonary artery catheter (PAC) via the superior vena cava (SVC) necessary. After transplantation, endomyocardial biopsy (EMB) is recommended for routine surveillance of heart transplant rejection again through the SVC. Case Presentation. In this report, we present a HTX patient who developed a SVC syndrome as a possible complication of all these procedures via the SVC. This 35-year-old Caucasian male could be successfully treated by balloon dilatation/angioplasty. Conclusion. The SVC syndrome can lead to pressure increase in the venous system such as edema in the head and the upper part of the body and further serious complications like cerebral bleeding and ischemia, or respiratory problems. Balloon angioplasty and stent implantation are valid methods to treat stenoses of the SVC successfully.

A Shocking Complication of a Pneumothorax: Chest Tube-Induced Arrhythmias and Review of the Literature Thu, 24 Jul 2014 08:43:29 +0000 http://www.hindawi.com/journals/cric/2014/681572/ We describe a patient with a recent chest tube insertion leading to atrial fibrillation with rapid ventricular rate that led to multiple inappropriate internal cardiac defibrillator (ICD) shocks. This is the first reported case of this occurring in a patient with an ICD leading to inappropriate shocks. Our elderly patient with emphysema presented with a spontaneous pneumothorax and developed rapid atrial fibrillation following emergency tube thoracostomy. The patient had a single lead ICD and received multiple inappropriate shocks for the rapid ventricular rate in the therapy zone. Although medical treatment helped stabilize the patient, resolution of the atrial fibrillation occurred only after the chest tube was removed. In a patient with a chest tube or other intrathoracic catheters, maintaining a high index of suspicion that chest tube insertions can cause secondary life threatening cardiovascular complications needs to be considered. In such patients, removal of the device proves to be the most prudent treatment action. Shaun Cardozo and Kevin Belgrave Copyright © 2014 Shaun Cardozo and Kevin Belgrave. All rights reserved. Novel Use of the GuideLiner Catheter to Deliver Rotational Atherectomy Burrs in Tortuous Vessels Wed, 23 Jul 2014 00:00:00 +0000 http://www.hindawi.com/journals/cric/2014/594396/ Rotational atherectomy (RA) for heavily calcified lesions is essential for improved stent delivery and stent expansion. In tortuous vessels it is often difficult to advance the burr without rotation and possible injury to the endothelium of healthy vessel. The GuideLiner catheter, a child in mother catheter, has recently been used to allow for increased support for delivery of stents through tortuous vessels. We report a novel use of the GuideLiner for the delivery of an RA burr in tortuous vessels requiring increased guide support.

Left Ventricle Pseudoaneurysm: Contribution of Multimodality Imaging to the Diagnosis Mon, 21 Jul 2014 07:18:45 +0000 http://www.hindawi.com/journals/cric/2014/531929/ The left ventricle pseudoaneurysm is an anomaly of the left ventricle and is severed and joined with a pocket look. There may be secondary to a myocardial infarction, trauma, or surgical procedure. Sometimes the cause is not found. Complications are heart failure, arrhythmias, vascular embolism, and sudden death. The treatment is surgical only. The authors report the case of a black patient of 64 years old, without medical history, had seen to a deformation of the cardiac shadow in radiography. The left ventricle pseudoaneurysm and in situ thrombus are visualized in echocardiography and CT scan. The patient is waiting for heart surgery.

Accidental Left Circumflex Artery to Right Lung Fistula in a Suspected Case of Pulmonary Hypertension Thu, 17 Jul 2014 07:28:21 +0000 http://www.hindawi.com/journals/cric/2014/427045/ A 56-year-old woman was referred to the cardiology department of the Shahid Modarres hospital. The patient had a history of pulmonary thromboembolism 20 years ago which had been managed by the inferior vena cava filter and since then the patient has been on warfarin. Her chief complaint was chronic dyspnea on exertion (NYHA class II) from several years ago. Right and left heart catheterization was performed for evaluation of pulmonary artery pressure. We found rich collateral formations between LCX as well as RCA and right pulmonary artery, primarily assumed as multiple fistulas. Among patients who have chronic thromboembolic pulmonary hypertension, systemic collateral supply to the pulmonary parenchyma has been previously reported to occur from both bronchial and/or nonbronchial systemic circulations. Our patient had neither signs of heart failure nor myocardial ischemia and, thus, was a candidate for conservative management. The adenosine pulmonary reactivity test was not performed because of low pulmonary pressure which had been estimated to be high.

Postpartum Coronary Vasospasm with Literature Review Mon, 07 Jul 2014 09:01:17 +0000 http://www.hindawi.com/journals/cric/2014/523023/ Acute myocardial infarction during pregnancy or the postpartum period is rare. We report a case of a 39-year-old postpartum woman who developed non-ST-elevation myocardial infarction due to severe diffuse coronary vasospasm. To our knowledge, this is the first case of angiographically evidenced coronary vasospasm, in a postpartum woman, with resistance to intracoronary nitroglycerin.

Shoshin Beriberi Induced by Long-Term Administration of Diuretics: A Case Report Thu, 03 Jul 2014 12:08:00 +0000 http://www.hindawi.com/journals/cric/2014/878915/ Previous studies have suggested that diuretic therapy for heart failure may lead to thiamine deficiency due to the increased urinary thiamine excretion. Herein, we present the case of a 61-year-old man with shoshin beriberi, a fulminant form of wet beriberi, induced by long-term diuretic therapy. The patient had a history of heart failure with preserved ejection fraction and was receiving furosemide and trichlormethiazide therapy. He presented with worsening exertional dyspnea and was admitted for heart failure exacerbation. His condition failed to improve even after intensive treatment. A hemodynamic evaluation with the Swan-Ganz catheter revealed high-output heart failure with low peripheral vascular resistance. Thiamine was administered for suspected shoshin beriberi; his hemodynamic status improved dramatically within the next six hours. The serum thiamine level was below the normal range; the patient was therefore diagnosed with shoshin beriberi. The common causes of thiamine deficiency were not identified. Long-term diuretic therapy with furosemide and thiazide was thought to have played a major role in the development of thiamine deficiency. This case illustrates the importance of considering wet beriberi as a possible cause of heart failure exacerbation in patients taking diuretics, even when the common thiamine deficiency causes are not identified with history-taking.

Iatrogenic Ascending Aorta Dissection during Diagnostic Coronary Angiography: Rare but Life-Threatening Mon, 16 Jun 2014 11:18:43 +0000 http://www.hindawi.com/journals/cric/2014/809398/ Dissection of the ascending aorta is a very rare but life-threatening complication during diagnostic angiography. We present a case of an elderly woman who underwent an elective diagnostic coronary angiography, complicated with an iatrogenic ascending aorta dissection that did not involve the coronary arteries but originated 4 cm distal of the aortic valve. The patient developed cardiogenic shock due to acute pericardial tamponade and so immediate, life-saving cardiac surgery with implantation of a supracoronary graft was successfully performed. A biopsy from the excised aorta showed loss of smooth muscle cells and accumulation of basophilic ground substance, clear features of cystic media necrosis. This is believed to be the underlying cause of the dissection besides a nonselective injection of the right coronary artery.

A Unique Case of Cardiac Arrest following K2 Abuse Sun, 25 May 2014 08:37:07 +0000 http://www.hindawi.com/journals/cric/2014/120607/ Sudden cardiac death (SCD) accounts for up to 450,000 deaths every year in the United States (Zipes et al. (2006)). Most cases of sudden cardiac death occur in subjects with no prior history of heart disease (Myerburg et al. (1998)). The incidence of sudden death in a general population has been shown to increase contemporaneously with substance abuse (Phillips et al. (1999)). The causative association of sudden death with cocaine, methadone, and volatile agents is well established (Adgey et al. (1995) and Isner et al. (1986)). We describe a case of out-of-hospital cardiac arrest temporally related to abuse of the synthetic cannabinoid street drug known as K2. To our knowledge, there are no previously documented cases of sudden cardiac death associated with synthetic cannabinoids although they have been linked to myocardial infarction in teenagers despite normal coronary angiography (Mir et al. (2011)). Saif Ibrahim, Farah Al-Saffar, and Thomas Wannenburg Copyright © 2014 Saif Ibrahim et al. All rights reserved. Recurrent Acute Nonrheumatic Streptococcal Myocarditis Mimicking STEMI in a Young Adult Thu, 22 May 2014 11:58:06 +0000 http://www.hindawi.com/journals/cric/2014/964038/ Myocarditis consists of an inflammation of the cardiac muscle, definitively diagnosed by endomyocardial biopsy. The causal agents are primarily infectious: in developed countries, viruses appear to be the main cause, whereas in developing countries rheumatic carditis, Chagas disease, and HIV are frequent causes. Furthermore, myocarditis can be indirectly induced by an infectious agent and occurs following a latency period during which antibodies are created. Typically, myocarditis observed in rheumatic fever related to group A streptococcal (GAS) infection occurs after 2- to 3-week period of latency. In other instances, myocarditis can occur within few days following a streptococcal infection; thus, it does not fit the criteria for rheumatic fever. Myocarditis classically presents as acute heart failure, and can also be manifested by tachyarrhythmia or chest pain. Likewise, GAS-related myocarditis reportedly mimics myocardial infarction (MI) with typical chest pain, electrocardiograph changes, and troponin elevation. Here we describe a case of recurrent myocarditis, 5 years apart, with clinical presentation imitating an acute MI in an otherwise healthy 37-year-old man. Both episodes occurred 3 days after GAS pharyngitis and resolved quickly following medical treatment. Amanda Chikly, Ronen Durst, Chaim Lotan, and Shmuel Chen Copyright © 2014 Amanda Chikly et al.
