A Case of Clozapine-Induced Myocarditis in a Young Patient with Bipolar Disorder Sun, 30 Aug 2015 13:53:24 +0000 http://www.hindawi.com/journals/cric/2015/283156/ We present a case of drug-induced myocarditis manifesting as acute heart failure in a young patient with bipolar disorder being treated for depression. The case describes a 20-year-old man being treated in the psychiatry ward for worsening depression when he started complaining of chest pain and shortness of breath. His list of medications included clozapine, lithium, lorazepam, and haloperidol. The main findings on physical examination were tachycardia, low-grade fever, crackles in both lung bases on auscultation, and the absence of any notable edema. Abnormal labs included a troponin of 0.9, with a CK of 245 and CK-MB of 3.1. An ECG revealed sinus tachycardia and left anterior fascicular block (LAFB). An echocardiogram revealed global hypokinesis, severe left ventricular dysfunction with an ejection fraction estimated at 20%. The patient had an admitting diagnosis of acute left ventricular systolic dysfunction likely secondary to drug-induced myocarditis (suspect clozapine) versus acute coronary syndrome. He was managed conservatively and transferred to another facility for endomyocardial biopsy confirming myocarditis. This case is an example of one of the most typical presentations of suspected drug-induced acute myocarditis and will hopefully prompt the reader to think of this underdiagnosed entity in the right clinical setting.

Respiratory Failure in an Adolescent with Primary Cardiac Sarcoma Wed, 19 Aug 2015 13:46:04 +0000 http://www.hindawi.com/journals/cric/2015/592385/ We report a case of progressive respiratory failure secondary to primary cardiac sarcoma masquerading as primary lung disease. An 18-year-old female presented to our hospital emergency department with progressive cough, dyspnea, and hemoptysis. She was treated for primary lung infection without improvement and had respiratory failure with endotracheal intubation by the third hospital day. An “intermediate” plasma brain natriuretic protein (BNP) of 216 pg/mL did not raise concerns about a heart failure diagnosis and may have delayed the correct diagnosis. Computed tomography of the chest with intravenous contrast was performed on the fifth hospital day and revealed a cardiac mass. A transthoracic echocardiogram confirmed a large left atrial mass that was obstructing mitral inflow. She was transferred to a tertiary center for emergency cardiac surgery. Primary cardiac tumors are a rare and treatable cause of heart failure in adolescent and young adult patients. Presentation can be confused with primary lung disease and must be suspected early. Plasma BNP cutoff levels used in the adult population should not be extrapolated to adolescents, as levels, both normal and abnormal, are significantly lower in this group of patients.

Mobile Intracardiac Mass after Inguinal Hernia Repair: An Unresolved Treatment Dilemma Sun, 16 Aug 2015 09:55:32 +0000 http://www.hindawi.com/journals/cric/2015/375089/ Right heart thrombi (RHT) are rare but well-described entity in literature. Their isolation has been considered as confirmatory for the diagnosis of venous thromboembolism (VTE). Even though their isolation aids the diagnosis, physicians are faced with a difficult management dilemma giving the paucity of data to support any treatment decision. We present a case of RHT in an 81-year-old man who presented to hospital with a large mobile right heart thrombus in transit seen on transthoracic echocardiogram (TTE). He was successfully treated with anticoagulation alone. This case highlights the importance of TTE in establishing the diagnosis and describes the interplay of factors influencing treatment decision.

Rare Case of Rapidly Worsening REM Sleep Induced Bradycardia Sun, 16 Aug 2015 09:14:38 +0000 http://www.hindawi.com/journals/cric/2015/546712/ Sinoatrial arrest also known as sinus pause occurs when sinoatrial node of the heart transiently ceases to generate the electrical impulse necessary for the myocardium to contract. It may last from 2.0 seconds to several minutes. Etiologies of sinoatrial arrest can be complex and heterogeneous. During rapid eye movement (REM) sleep, sinus arrests unrelated to apnea or hypopnea are very rare and only a few cases have been reported. Here we report a case of 36-year-old male with no significant past medical history who presented to our hospital after a syncopal episode at night. Physical examination showed no cardiac or neurological abnormalities and initial EKG and neuroimaging were normal. Overnight telemonitor recorded several episodes of bradyarrhythmia with sinus arrest that progressively lengthened over time. Sleep study was done which confirmed that sinus arrests occurred more during REM sleep and are unrelated to apnea or hypopnea. Electrophysiology studies showed sinus nodal dysfunction with no junctional escape, subsequently a dual chamber pacemaker placed for rapidly worsening case of REM sleep induced bradycardia.

Transapical Implantation of a 2nd-Generation JenaValve Device in Patient with Extremely High Surgical Risk Tue, 04 Aug 2015 11:44:38 +0000 http://www.hindawi.com/journals/cric/2015/458151/ Transcatheter Aortic Valve Replacement (TAVR) is performed in patients who are poor surgical candidates. Many patients have inadequate femoral access, and alternative access sites have been used such as the transapical approach discussed in this paper. We present an elderly and fragile patient not suitable for surgery for unacceptable high risk, including poor ventricular function, previous myocardial infarction with percutaneous coronary intervention, pericardial effusion, and previous cardiac surgery with replacement of mechanical mitral valve. Transapical aortic valve replacement with a second-generation self-expanding JenaValve is performed. The JenaValve is a second-generation transapical TAVR valve consisting of a porcine root valve mounted on a low-profile nitinol stent. The valve is fully retrievable and repositionable. We discuss transapical access, implantation technique, and feasibility of valve implantation in this extremely high surgical risk patient.

Early Cardiac Tamponade in a Patient with Postsurgical Hypothyroidism Thu, 30 Jul 2015 11:30:23 +0000 http://www.hindawi.com/journals/cric/2015/310350/ Pericardial effusion is a common cardiac manifestation of hypothyroidism, but effusion resulting in cardiac tamponade is extremely rare. We present a case of a 56-year-old African American woman with slurred speech and altered mental status that was initially suspected to have stroke. Her chest X-ray revealed cardiomegaly and subsequent echocardiogram showed a large pericardial effusion with echocardiographic evidence of cardiac tamponade. Clinically, patient did not have pulsus paradoxus or hypotension. Further questioning revealed a history of total surgical thyroidectomy and noncompliance with thyroid replacement therapy. Pericardiocentesis was performed promptly and thyroxine replacement therapy was started. Thereafter, her mental status improved significantly. The management of pericardial effusion associated with hypothyroidism varies depending on size of effusion and hemodynamic stability of the patient. The management strategy ranges from conservative management with close monitoring and thyroxine replacement to pericardiocentesis or creation of a pericardial window.

Biventricular Noncompaction Cardiomyopathy in an Adult with Unique Facial Dysmorphisms: Case Report and Brief Review Tue, 21 Jul 2015 12:24:02 +0000 http://www.hindawi.com/journals/cric/2015/831341/ Left ventricular noncompaction (LVNC) is a rare cardiomyopathy that is believed it to arise from an arrest in embryonic endomyocardial development. More recent studies suggest that it can be acquired later on in life sporadically. It may be accompanied by life-threatening complications, which are most commonly heart failure, arrhythmias, and thromboembolic events. We report a case of biventricular noncompaction cardiomyopathy in a 36-year-old man presenting for the first time with clinical heart failure as well as atrial arrhythmia. Transthoracic echocardiography (TTE) revealed LVNC with depressed ejection fraction (EF). Cardiac magnetic resonance imaging (MRI) further revealed a left atrial appendage thrombus as well as right ventricular noncompaction involvement. His physical exam was unique for a characteristic facial dysmorphisms pattern and developmental delays reminiscent of the earliest descriptions of LVNC in the pediatric population and it was rarely described in adult patients. This unique presentation underscores the importance of a better understanding of the genetics and natural course of LVNC. This will help us to elucidate the uncertainty surrounding its clinical management, discussed in a brief review of the literature following the case.

Mesalazine-Induced Myopericarditis in a Patient with a Recent Diagnosis of Crohn’s Disease: Apropos of a Case Tue, 21 Jul 2015 12:23:20 +0000 http://www.hindawi.com/journals/cric/2015/728310/ Mesalazine- (5-aminosalicylic acid-) containing products are a well-known treatment for inflammatory bowel disease, often as first line. Myocarditis is recognized as a very rare possible side effect of this drug treatment. We present a case of mesalazine-induced myopericarditis that was successfully improved by immediate cessation of the medication.

Giant Cell Myocarditis: Not Always a Presentation of Cardiogenic Shock Thu, 16 Jul 2015 07:24:41 +0000 http://www.hindawi.com/journals/cric/2015/173826/ Giant cell myocarditis is a rare and often fatal disease. The most obvious presentation often described in the literature is one of rapid hemodynamic deterioration due to cardiogenic shock necessitating urgent consideration of mechanical circulatory support and heart transplantation. We present the case of a 60-year-old man whose initial presentation was consistent with myopericarditis but who went on to develop a rapid decline in left ventricular systolic function without overt hemodynamic compromise or dramatic symptomatology. Giant cell myocarditis was confirmed via endomyocardial biopsy. Combined immunosuppression with corticosteroids and calcineurin inhibitor resulted in resolution of symptoms and sustained recovery of left ventricular function one year later. Our case highlights that giant cell myocarditis does not always present with cardiogenic shock and should be considered in the evaluation of new onset cardiomyopathy of uncertain etiology as a timely diagnosis has distinct clinical implications on management and prognosis.

Malignant Course of Anomalous Left Coronary Artery Causing Sudden Cardiac Arrest: A Case Report and Review of the Literature Wed, 15 Jul 2015 12:49:11 +0000 http://www.hindawi.com/journals/cric/2015/806291/ Sudden cardiac arrest has been reported to occur in patients with congenital anomalous coronary artery disease. About 80% of the anomalies are benign and incidental findings at the time of catheterization. We present a case of sudden cardiac arrest caused by anomalous left anterior descending artery. 61-year-old African American female was brought to the emergency department after sudden cardiac arrest. Initial EKG showed sinus rhythm with RBBB and LAFB with nonspecific ST-T wave changes. Coronary angiogram revealed no atherosclerotic disease. The left coronary artery was found to originate from the right coronary cusp. Cardiac CAT scan revealed similar findings with interarterial and intramural course. Patient received one-vessel arterial bypass graft to her anomalous coronary vessel along with a defibrillator for secondary prevention. Sudden cardiac arrest secondary to congenital anomalous coronary artery disease is characterized by insufficient coronary flow by the anomalous left coronary artery to meet elevated left ventricular (LV) myocardial demand. High risk defects include those involved with the proximal coronary artery or coursing of the anomalous artery between the aorta and pulmonary trunk. Per guidelines, our patient received one vessel bypass graft to her anomalous vessel. It is important for clinicians to recognize such presentations of anomalous coronary artery.

Severe Hyperthyroidism Presenting with Acute ST Segment Elevation Myocardial Infarction Tue, 14 Jul 2015 09:17:07 +0000 http://www.hindawi.com/journals/cric/2015/901214/ Introduction. Acute myocardial infarction is life-threatening. A cardiac troponin rise accompanied by typical symptoms, ST elevation or depression is diagnostic of acute myocardial infarction. Here, we report an unusual case of a female who was admitted with chest pain. However, she did not present with a typical profile of an acute myocardial infarction patient. Case Presentation. A 66-year-old Han nationality female presented with chest pain. The electrocardiogram (ECG) revealed arched ST segment elevations and troponin was elevated. However, the coronary angiography showed a normal coronary arterial system. Thyroid function tests showed that this patient had severe hyperthyroidism. Conclusion. Our case highlights the possibility that hyperthyroidism may cause a large area of myocardium injury and ECG ST segment elevation. We suggest routine thyroid function testing in patients with chest pain. Dayan Zhou, Zongjie Qu, Hao Wang, Zhe Wang, and Qiang Xu Copyright © 2015 Dayan Zhou et al. All rights reserved. Takotsubo Cardiomyopathy: A New Perspective in Asthma Sun, 12 Jul 2015 09:43:51 +0000 http://www.hindawi.com/journals/cric/2015/640795/ Takotsubo cardiomyopathy (TCM) is an entity of reversible cardiomyopathy known for its association with physical or emotional stress and may mimic myocardial infarction. We report an exceedingly rare case of albuterol-induced TCM with moderate asthma exacerbation. An interesting association that may help in understanding the etiology of TCM in the asthmatic population. Although the prognosis of TCM is excellent, it is crucial to recognize beta agonists as a potential stressor. Fady Y. Marmoush, Mohamad F. Barbour, Thomas E. Noonan, and Mazen O.

Superdominant Right Coronary Artery with Absence of Left Circumflex and Anomalous Origin of the Left Anterior Descending Coronary from the Right Sinus: An Unheard Coronary Anomaly Circulation Thu, 09 Jul 2015 08:27:55 +0000 http://www.hindawi.com/journals/cric/2015/721536/ Coronary artery anomalies are congenital changes in their origin, course, and/or structure. Most of them are discovered as incidental findings during coronary angiographic studies or at autopsies. We present herein the case of a 70-year-old man with symptomatic severe aortic valvar stenosis whose preoperative coronary angiogram revealed a so far unreported coronary anomaly circulation pattern.

Ebstein’s Anomaly, Left Ventricular Noncompaction, and Sudden Cardiac Death Thu, 09 Jul 2015 08:04:09 +0000 http://www.hindawi.com/journals/cric/2015/854236/ Ebstein’s anomaly is a congenital disorder characterized by apical displacement of the septal leaflet of the tricuspid valve. Ebstein’s anomaly may be seen in association with other cardiac conditions, including patent foramen ovale, atrial septal defect, and left ventricular noncompaction (LVNC). LVNC is characterized by increased trabeculation within the left ventricular apex. Echocardiography is often used to diagnose LVNC; however, magnetic resonance (MR) imaging offers superior characterization of the myocardium. We report a case of sudden cardiac death in a patient with Ebstein’s anomaly with unrecognized LVNC noted on post mortem examination with screening documenting the presence of LVNC in one of the patient’s twin sons.

A Large Intra-Abdominal Hiatal Hernia as a Rare Cause of Dyspnea Wed, 01 Jul 2015 06:48:11 +0000 http://www.hindawi.com/journals/cric/2015/546395/ Giant hiatal hernias, generally seen at advanced ages, can rarely cause cardiac symptoms such as dyspnea and chest pain. Here, we aimed to present a case with a large hiatal hernia that largely protruded to intrathoracic cavity and caused dyspnea, particularly at postprandial period, by compressing the left atrium and right pulmonary vein. We considered presenting this case as large hiatal hernia is a rare, intra-abdominal cause of dyspnea.

Aortico-Left Atrial Fistula: A Rare Complication of Bioprosthetic Aortic Valve Endocarditis Secondary to Enterococcus faecalis Sun, 28 Jun 2015 10:29:03 +0000 http://www.hindawi.com/journals/cric/2015/473246/ Paravalvular aortic root abscess with intracardiac fistula formation is an exceedingly rare complication of infective endocarditis. This condition is even more rarely encountered in patients with bioprosthetic valve endocarditis. We report an unusual case of a 68-year-old Bosnian female with a bioprosthetic aortic valve, who developed an extensive aortic root abscess, complicated by an aortico-left atrial intracardiac fistula. This case illustrates that a high index of suspicion, prompt diagnosis by echocardiography, proper antibiotic therapy, and early surgical intervention are crucial to improving treatment outcomes for this rare condition.

Pulmonic Valve Repair in a Patient with Isolated Pulmonic Valve Endocarditis and Sickle Cell Disease Tue, 23 Jun 2015 11:38:46 +0000 http://www.hindawi.com/journals/cric/2015/732073/ A 49-year-old woman with sickle cell disease presented with one month of exertional dyspnea, weakness, and fever and was diagnosed with isolated pulmonic valve endocarditis secondary to methicillin-resistant Staphylococcus bacteremia in the setting of a peripherally inserted central venous catheter. Chest computerized tomography showed multiple bilateral pulmonary nodular opacities consistent with septic emboli. Transthoracic and transesophageal echocardiograms revealed a large echodensity on the pulmonic valve requiring vegetation excision and pulmonic valve repair. In conclusion, isolated pulmonic valve endocarditis is a rare cause of infective endocarditis that warrants a high index of clinical suspicion. Furthermore the management of patients with sickle cell disease and endocarditis requires special consideration.

Pneumopericarditis: A Case of Acute Chest Pain with ST Segment Elevation Sun, 14 Jun 2015 13:39:43 +0000 http://www.hindawi.com/journals/cric/2015/256546/ Pneumopericarditis describes a clinical scenario where fluid and air are found within the pericardial space. Although infrequent, pneumopericarditis should be considered in patients presenting with acute chest pain as a differential diagnosis. This is relevant in patients with history of upper gastrointestinal (GI) surgery, as this may lead to a fistula communicating the GI tract and the pericardium. We report a 42-year-old man with history of numerous surgical interventions related to a Nissen fundoplication that presented with acute chest pain and inferior lead ST segment elevations. Emergent coronary angiography was negative for coronary vascular disease but fluoroscopy revealed air in the pericardial space. Subsequent radiographic studies helped confirm air in the pericardial space with a fistulous communication to the stomach. Ultimate treatment for this defect was surgical closure. Erwin E.

Beneficial Effects of Isoproterenol and Quinidine in the Treatment of Ventricular Fibrillation in Brugada Syndrome Thu, 11 Jun 2015 12:54:18 +0000 http://www.hindawi.com/journals/cric/2015/753537/ The use of an implantable cardiac defibrillator has been advocated as the only effective treatment for the management of ventricular fibrillation (VF) in patients with Brugada Syndrome (BrS). However, this device is only useful for terminating VF. Intermittent and/or recalcitrant VF for which lifesaving cardioversion occurs is a problematic situation in this patient population. The immediate use of appropriate antiarrhythmics in the acute setting has proven to be lifesaving. Quinidine has been well established as an effective antiarrhythmic in BrS, while isoproterenol (ISP) has had some recognition as well. The addition of drug therapy to prevent the induction of these arrhythmias has been shown to reduce the morbidity and mortality associated with BrS. It was proven to be especially effective in the presence of early repolarization, evidenced by the reduction or normalization of the early repolarization pattern on ECG. Thus, for the prophylactic management and long term suppression of VF in BrS, further prospective studies should be performed to determine the effectiveness of quinidine and ISP in this patient population.

Noncompaction Cardiomyopathy with Charcot-Marie-Tooth Disease Tue, 09 Jun 2015 16:54:27 +0000 http://www.hindawi.com/journals/cric/2015/646890/ We report a case of a 53-year-old female presenting with a new-onset heart failure that was contributed secondary to noncompaction cardiomyopathy. The diagnosis was made by echocardiogram and confirmed by cardiac MRI. Noncompaction cardiomyopathy (also known as ventricular hypertrabeculation) is a newly discovered disease. It is considered to be congenital (genetic) cardiomyopathy. It is usually associated with genetic disorders and that could explain the genetic pathogenesis of the non-compaction cardiomyopathy. Our case had a history of Charcot-Marie-Tooth disease. There is a high incidence of arrhythmia and embolic complications. The treatment usually consists of the medical management, defibrillator placement, and lifelong anticoagulation. Heart transplantation will be the last resort.

Acute Anterior Myocardial Infarction Accompanied by Acute Inferior Myocardial Infarction: A Very Rare Coronary Artery Anomaly Sun, 07 Jun 2015 08:34:33 +0000 http://www.hindawi.com/journals/cric/2015/347126/ Coronary artery anomalies are rare and mostly silent in clinical practice. First manifestation of this congenital abnormality can be devastating as syncope, acute coronary syndrome, and sudden cardiac death. Herein we report a case with coronary artery anomaly complicated with ST segment myocardial infarction in both inferior and anterior walls simultaneously diagnosed during primary percutaneous coronary intervention.

A Complicated Case of Triple Valve Infective Endocarditis in an IV Drug User with a Bicuspid Aortic Valve Requiring Three Separate Salvage Operations: A Case Report and Literature Review Wed, 03 Jun 2015 11:56:46 +0000 http://www.hindawi.com/journals/cric/2015/291079/ Infective endocarditis (IE) is an infection of the endocardium that involves valves and adjacent mural endocardium or a septal defect. Local complications include severe valvular insufficiency, which may lead to intractable congestive heart failure and myocardial abscesses. If left untreated, IE is generally fatal. Diagnosing IE can be straightforward in patients with the typical oslerian manifestations such as bacteremia, evidence of active valvulitis, peripheral emboli, and immunologic vascular phenomena. In the acute course, however, the classic peripheral stigmata may be few or absent, particularly among intravenous drug abuse (IVDA) patients in whom IE is often due to a S. aureus infection of right-sided heart valves. We present a complicated case of a very aggressive native aortic valve MSSA (methicillin sensitive Staphylococcus aureus) IE in a young adult male with a past medical history of bicuspid aortic valve and IV drug abuse. His clinical course was complicated by aortic valve destruction and development of third-degree AV block, as well as an aorto-left atrial fistula requiring emergent operation for AV replacement and patch repair. The patient required two reoperations for recurrent endocarditis and its complications.

Fibromuscular Dysplasia Leading to Spontaneous Coronary Artery Dissection with Sudden Cardiac Arrest Wed, 03 Jun 2015 09:55:32 +0000 http://www.hindawi.com/journals/cric/2015/708409/ A 30-year-old previously healthy female, who was six-week postpartum, experienced sudden collapse and tonic-clonic seizure. Emergency medicine services arrived at the scene and the patient was found to be in ventricular fibrillation. Advanced cardiovascular life support (ACLS) was initiated with return of spontaneous circulation. Afterwards, her initial EKG showed atrial fibrillation with rapid ventricular rate, ST elevation in leads II, III, and aVF, and ST depression in V2–V4. She was transferred to a tertiary care hospital where emergent angiogram was performed revealing obstruction of blood flow in the proximal and mid right coronary artery (RCA). A hazy and irregularly contoured appearance of the RCA was consistent with diagnosis of fibromuscular dysplasia. Subsequently, intravascular ultrasonogram (IVUS) was performed which confirmed the diagnosis of RCA dissection. Successful revascularization of the RCA was performed using two bare mental stents. After a complicated course in hospital, she was discharged in stable condition and did very well overall. Ata Bajwa, Udit Bhatnagar, Amit Sharma, Hani El-Halawany, and Randall C.

Instant Stent-Accentuated Three-Dimensional Optical Coherence Tomography Guided Selection of Proper Distal Cell for Side Branch Dilatation in Bifurcation Stenting Sun, 31 May 2015 08:42:38 +0000 http://www.hindawi.com/journals/cric/2015/915084/ In the bifurcation stenting, the distal rewiring for the side branch postdilatation confirmed by two-dimensional modalities may not lead to favorable results in some cases. If there are two distal cells divided by the link bridging from the carina, the rewiring through the larger distal cell may be recommended for the side branch postdilatation. Detailed confirmation of the rewired cell by the intraprocedural instant stent-accentuated three-dimensional optical coherence tomography is important. Fumiaki Nakao Copyright © 2015 Fumiaki Nakao.

Undifferentiated Intimal Sarcoma of the Inferior Vena Cava with Extension to the Right Atrium and Renal Vasculature Thu, 28 May 2015 13:47:51 +0000 http://www.hindawi.com/journals/cric/2015/812374/ Primary sarcomas of the great vessels (aorta, pulmonary artery, and inferior vena cava (IVC)) are exceedingly rare. We report a rare case of an undifferentiated intimal sarcoma of the IVC with extension to the right atrium, adrenal, and renal veins. The patient underwent extensive resection, reconstruction of the IVC, and subsequent adjuvant chemotherapy. Patient has tolerated chemotherapy and, at 17 months after resection, the patient remains free of tumor recurrence. Undifferentiated intimal sarcomas remain a rare entity with only five cases of venous undifferentiated intimal sarcomas reported in the literature, two of which occurred in the IVC. Intimal sarcomas tend to carry a poor prognosis with the limited literature available on treatment approaches. Our objective is to highlight this rare entity and possible treatment approach which we utilized. Primary sarcomas of IVC need to be included as part of a complete differential diagnosis in patients with atrial masses or recurrent pulmonary emboli. Aasim M.

Raghib Syndrome Presenting as a Cryptogenic Stroke: Role of Cardiac MRI in Accurate Diagnosis Wed, 27 May 2015 12:03:03 +0000 http://www.hindawi.com/journals/cric/2015/921247/ Raghib Syndrome is a rare developmental complex, which consists of persistence of the left superior vena cava (PLSVC) along with coronary sinus ostial atresia and atrial septal defect. This Raghib complex anomaly has also been associated with other congenital malformations including ventricular septal defects, enlargement of the tricuspid annulus, and pulmonary stenosis. Our case demonstrates an isolated PLSVC draining into the left atrium along with coronary sinus atresia in a young patient presenting with cryptogenic stroke without the atrial septal defect. Majority of the cases reported in the literature were found to have the lesion during the postmortem evaluation or were characterized at angiography and/or echocardiography. We stress the importance of modern day imaging like the computed tomography (CT) angiography and cardiac MRI in diagnosis and surgical management of such rare lesions leading to cryptogenic strokes.

Acute Amiodarone Pulmonary Toxicity after Drug Holiday: A Case Report and Review of the Literature Thu, 14 May 2015 12:30:40 +0000 http://www.hindawi.com/journals/cric/2015/927438/ Amiodarone is reported to cause a wide continuum of serious clinical effects. It is often challenging to detect Amiodarone-induced pulmonary toxicity (AIPT). Typically, the diagnosis is made based on the clinical settings and may be supported by histopathology results, if available. We describe a 57-year-old patient who developed severe rapidly progressive respiratory failure secondary to AIPT with acute bilateral infiltrates and nodular opacities on chest imaging. Interestingly, Amiodarone was discontinued 3 weeks prior to his presentation. He had normal cardiac filling pressures confirmed by echocardiography. To our knowledge, this is the first case of isolated acute lung injury induced by Amiodarone, three weeks after therapy cessation, with adequate clinical improvement after supportive management and high dose steroid therapy.

Aortopulmonary Fistula after Multiple Pulmonary Artery Stenting and Dilatation for Postarterial Switch Supravalvular Stenosis Wed, 13 May 2015 09:30:01 +0000 http://www.hindawi.com/journals/cric/2015/371925/ We present a case of iatrogenic aortopulmonary fistula following pulmonary artery (PA) stenting late after arterial switch operation (ASO) for D-transposition of the great arteries (D-TGA), an unusual complication that may be encountered more frequently in contemporary adult cardiology clinics. The diagnosis should be sought in the face of unexplained heart failure in patients who underwent ASO and subsequent PA angioplasty. Treatment should be instituted in a timely fashion, and options include surgical correction or implantation of a duct occluder or covered stent.

Free Floating Right Heart Thrombus Associated with Acute Pulmonary Embolism: An Unsettled Therapeutic Difficulty Mon, 11 May 2015 08:12:46 +0000 http://www.hindawi.com/journals/cric/2015/364780/ Free floating right heart thrombus is a rare phenomenon in the context of acute pulmonary embolism and it is associated with a poor outcome. The increased use of echocardiography has led to an increased detection of right heart thrombi. However, optimal management of free floating right heart thrombus remains controversial with no clear consensus. We present the case of a 74-year-old woman who presented to the emergency department with acute onset dyspnea on minimal exertion which had developed over a period of 1 day. A computed tomography of the chest demonstrated massive bilateral proximal pulmonary embolism. A bedside transthoracic echocardiography performed showed a moderately dilated, poorly functioning right ventricle with visible highly mobile serpiginous thrombus moving to and fro across the tricuspid valve. Thrombolytic therapy was immediately initiated with tenecteplase which resulted in excellent results. Although there is no clear consensus for the management of right heart thrombus associated with pulmonary embolism, thrombolysis is readily available and can be effective in carefully selected patients.
