Detection of the “Crossed Aorta Sign” during Echocardiography before Angiography Thu, 14 Dec 2017 09:43:28 +0000 http://www.hindawi.com/journals/cric/2017/9249821/ We report the case of an anomalous circumflex (Cx) origin from the right sinus of Valsalva with retroaortic course observed in a modified apical four-chamber view during transthoracic study (TTE). This finding is known as the “crossed aorta sign.” Usually, the diagnosis of this congenital anomaly of coronary circulation is established during coronary angiography. In this case, the diagnosis was performed by echocardiography before angiography. We believe that recent improvements in echocardiography increase the potential of this imaging technology also in the diagnosis of coronary artery anomalies.

Rare Case of Cocaine-Induced Aortic Aneurysm: A Near Dissection Event Thu, 14 Dec 2017 00:00:00 +0000 http://www.hindawi.com/journals/cric/2017/1785410/ Cocaine use has been associated with cardiovascular complications such as coronary atherosclerosis, coronary artery spasm, cardiac arrhythmias, acute myocardial infarction, myocarditis, and dilated cardiomyopathies. Aortic dissection is a rare but life-threatening complication of cocaine use. Cocaine and stimulant use can cause aortic aneurysm by increasing the aortic wall stress, and the most feared complications are dissection, rupture, and death. There are no clear guidelines about screening cocaine abusers with CT scan of the chest. We do not know if the number of years of cocaine use or the amount of cocaine use can be associated with higher incidence of aortic aneurysm or dissection. Cocaine-induced aortic aneurysm does not have any specific clinical feature. Common presentation is chest discomfort or chest pain. This common presentation is bewildering enough for clinicians to think of more common causes of chest pain like myocardial infarction and myocarditis. The sudden onset of severe, sharp, stabbing chest or back pain is suggestive of aortic dissection. Here, we present a young otherwise healthy patient with chronic cocaine use presenting with chest pain and found to have significant size aortic aneurysm.

ST Segment Elevation Is Not Always Myocardial Infarction: A Case of Focal Myopericarditis Wed, 29 Nov 2017 00:00:00 +0000 http://www.hindawi.com/journals/cric/2017/3031792/ Protocols exist on how to manage STEMI patients, with well-established timelines. There are times when patients present with chest pain, ST segment elevation, and biomarker elevation that are not due to coronary artery disease. These conditions usually present with normal coronary angiography. We present a case that was clinically indistinguishable from STEMI and that was diagnosed with focal myopericarditis on cardiac MRI.

Ventricular Fibrillation following Varicella Zoster Myocarditis Thu, 23 Nov 2017 00:00:00 +0000 http://www.hindawi.com/journals/cric/2017/1017686/ Varicella-zoster virus (VZV) infection can rarely lead to serious cardiac complications and life-threatening arrhythmias. We present a case of a 46-year-old male patient who developed VZV myocarditis and presented with recurrent syncopal episodes followed by a cardiac arrest. He had a further collapse eight years later, and cardiac magnetic resonance imaging (MRI) demonstrated mild mid-wall basal and inferolateral wall fibrosis. He was treated with an implantable cardioverter defibrillator (ICD) and represented two years later with ICD shocks, and interrogation of the device revealed ventricular fibrillation episodes. This case demonstrates the life-threatening long-term sequelae of VZV myocarditis in adults. We suggest that VZV myocarditis should be considered in all patients who present with a syncopal event after VZV infection. In these patients, ICD implantation is a potentially life-saving procedure.

Anticoagulation for the Pregnant Patient with a Mechanical Heart Valve, No Perfect Therapy: Review of Guidelines for Anticoagulation in the Pregnant Patient Wed, 22 Nov 2017 00:00:00 +0000 http://www.hindawi.com/journals/cric/2017/3090273/ Heart valve replacement with a mechanical valve requires lifelong anticoagulation. Guidelines currently recommend using a vitamin K antagonist (VKA) such as warfarin. Given the teratogenic effects of VKAs, it is often favorable to switch to heparin-derived therapies in pregnant patients since they do not cross the placenta. However, these therapies are known to be less effective anticoagulants subjecting the pregnant patient to a higher chance of a thrombotic event. Guidelines currently recommend pregnant women requiring more than 5 mg a day of warfarin be switched to alternative therapy during the first trimester. This case report highlights a patient who was switched to alternative therapy during her first pregnancy and suffered a devastating cerebrovascular accident (CVA). Further complicating her situation was during a subsequent pregnancy; this patient continued warfarin use during the first trimester and experienced multiple transient ischemic attacks (TIAs). This case highlights the increased risk of thrombotic events in pregnant patients with mechanical valves. It also highlights the difficulty of providing appropriate anticoagulation for the pregnant patient who has experienced thrombotic events on multiple anticoagulants.

Subacute Right Ventricular Perforation by Pacemaker Lead Causing Left-Sided Hemothorax and Epicardial Hematoma Thu, 16 Nov 2017 10:24:25 +0000 http://www.hindawi.com/journals/cric/2017/1264734/ We report a case of right ventricular wall perforation by a pacemaker lead in a 78-year-old female 18 days after a permanent pacemaker insertion. This injury necessitated explant of the perforating lead and implantation of a new one with surgical backup. We review the literature and discuss the possible risk and protective factors including lead models that were associated with higher incidence of perforation. We review the traditional pacing parameters and their lack of reliability to diagnose perforation and the need for low threshold to utilize imaging in appropriate clinical scenarios. The authors believe this case is of educational value to all health care professionals, especially emergency medicine and internal medicine residents, who routinely see patients with pacemakers complaining of chest pain, shortness of breath, or dizziness.

The Use of Adenosine to Enable Safe Implantation of Transcatheter Tricuspid Valve Thu, 16 Nov 2017 00:00:00 +0000 http://www.hindawi.com/journals/cric/2017/2760580/ High precision is necessary during percutaneous transcatheter heart valve implantation. The precision of the implantation has been established by increasing the heart rate (usually to 200 beats per minute) to the point of significantly reduced cardiac output and thus minimizing valve movement. Routinely, this tachycardia is induced by rapid pacing. Here we report a case of failure to pace during valve-in-valve (VIV) Edwards Sapien XT implantation in the tricuspid valve position. Transient cardiac arrest was induced by intravenous adenosine injection enabling accurate valve implantation. Vicki Zeniou, Shmuel Chen, Mony Shuvy, David Luria, Chaim Lotan, and Haim D.

AngioVac System Used for Vegetation Debulking in a Patient with Tricuspid Valve Endocarditis: A Case Report and Review of the Literature Tue, 07 Nov 2017 00:00:00 +0000 http://www.hindawi.com/journals/cric/2017/1923505/ AngioVac is a vacuum-based device approved in 2014 for percutaneous removal of undesirable materials from the intravascular system. Although numerous reports exist with regard to the use of the AngioVac device in aspiration of iliocaval, pulmonary, upper extremity, and right-sided heart chamber thrombi, very few data are present demonstrating its use in treatment of right-sided endocarditis. In this case report, we describe the novel device used in debulking a large right-sided tricuspid valve vegetation reducing the occurrence of septic embolisation and enhancing the efficacy of antibiotics in clearance of bloodstream infection. Further research is needed in larger RSIE patient populations to confirm the benefits and the potential of improved outcomes associated with the AngioVac device as well as identify its potential complications.

Congenital Absence of Left Circumflex Artery: A Case Report and Review of the Literature Mon, 30 Oct 2017 00:00:00 +0000 http://www.hindawi.com/journals/cric/2017/6579847/ Congenital absence of the left circumflex artery is a rare coronary anomaly with few reported cases in the literature. These patients are usually diagnosed incidentally when they undergo coronary angiography or coronary CT to rule out underlying coronary artery disease. In this article, we report a case of a 46-year-old man who was incidentally found to have a congenitally absent left circumflex artery with a superdominant right coronary artery after a workup was initiated for frequent premature ventricular contractions and regional wall motion on echocardiogram. A review of the clinical presentation, symptoms, and diagnostic modalities used to diagnose this entity is presented.

Deglutition Syncope: Two Case Reports Attributed to Vagal Hyperactivity Wed, 25 Oct 2017 09:57:03 +0000 http://www.hindawi.com/journals/cric/2017/2145678/ Deglutition syncope is a relatively rare cause of syncope that belongs to the category of neurally mediated reflex syncopal syndromes. The phenomenon is related to vagal reflex in context to deglutition causing atrioventricular block and acute reduction in cardiac output leading to dizziness or syncope. We present case series of two cases of deglutition syncope, of which first was managed medically and second with pacemaker implantation.

A Rare Manifestation of Asymptomatic Ebstein’s Anomaly with Tricuspid Valve Endocarditis Wed, 25 Oct 2017 00:00:00 +0000 http://www.hindawi.com/journals/cric/2017/7630915/ Ebstein’s anomaly is a rare congenital heart disease that presents with apical displacement of the septal and posterior leaflets of the tricuspid valve. It has a wide spectrum of clinical presentations and has been shown to manifest itself any time from birth to adulthood. Our patient is a 43-year-old male with a history of intravenous heroin abuse who presented to the emergency department with worsening shortness of breath and lower extremity edema. He denied any prior cardiac history. A transthoracic echo showed normal left ventricular function, but a large 2.2 × 2.1 cm echodensity on the septal leaflet of the tricuspid valve consistent with vegetation with severe tricuspid regurgitation and probable leaflet perforation. It also demonstrated severe right heart enlargement with atrialization of the right ventricle and apical displacement of the tricuspid valve consistent with Ebstein’s anomaly. This is a rare case of an adult who presented with asymptomatic Ebstein’s anomaly. There have been few reports of tricuspid valve endocarditis with Ebstein’s anomaly in the literature. To our knowledge, this represents the fifth reported case of a new diagnosis of Ebstein’s anomaly in the setting of endocarditis and the second case of Ebstein’s anomaly and endocarditis in an intravenous drug abuser.

Right Atrial Fibroelastoma Presenting as Typical Atrial Flutter: Rare Disease in Unusual Location Tue, 10 Oct 2017 00:00:00 +0000 http://www.hindawi.com/journals/cric/2017/4764587/ Typical atrial flutter as initial presentation of papillary fibroelastoma involving the cavotricuspid isthmus is not described before in literature. To our knowledge only 14 cases have been reported in literature involving the right atrium. Very unusual location is at the junction between inferior vena cava (IVC) and right atria as only 1 case has been reported.

D-Shaped Left Ventricle, Anatomic, and Physiologic Implications Sun, 08 Oct 2017 00:00:00 +0000 http://www.hindawi.com/journals/cric/2017/4309165/ Right ventricular loading/pressure influences left ventricular function because the two ventricles pump in series and because they are anatomically arranged in parallel, sharing the common ventricular septum. Flattening of the interventricular septum detected during echocardiographic examination is called D-shaped left ventricle. We present a case of an elderly male of African descent, who presented with increased shortness of breath. Transthoracic echocardiogram showed flattening and left sided deviation of interventricular septum causing a decreased size in left ventricle, secondary to volume/pressure overload in the right ventricle. While patient received hemodialysis therapy and intravascular volume was removed, patient blood pressure was noted to increase, paradox. Repeated transthoracic echocardiogram demonstrated less left deviation of interventricular septum compared with previous echocardiogram. We consider that it is important for all physicians to be aware of the anatomic and physiologic implication of D-shaped left ventricle and how right ventricle pressure/volume overload affects its function and anatomy.

Parachute-Like Mitral Valve Tuberculoma: A Rare Presentation Sun, 08 Oct 2017 00:00:00 +0000 http://www.hindawi.com/journals/cric/2017/1023924/ There have been anecdotal reports of tuberculous cardiac involvement, mainly in cases of military tuberculosis or immune deficient individuals. The spectrum of clinical presentations of tuberculous cardiac involvements includes incidental detection of single and multiple well-circumscribed tuberculomas, symptomatic obstructive lesions, AV conduction abnormalities, and even sudden death. We present a case of cardiac tuberculoma in an immune-competent person who presented with worsening dyspnea. The unique morphology of this mass posed an imaging challenge that required 4-dimensional (4D) echocardiography and cardiac magnetic resonance (CMR) detail to differentiate the mass from an anterior mitral leaflet (AML) aneurysm. Histological examination after surgical resection confirmed its tuberculous etiology. Arslan Masood, Gul Zaman Khan, Irfan Bashir, and Zubair Akram Copyright © 2017 Arslan Masood et al.

Postintervention Dyspnea after Radiofrequency Catheter Ablation: Think of a Phrenic Nerve Injury Wed, 04 Oct 2017 00:00:00 +0000 http://www.hindawi.com/journals/cric/2017/6418070/ Phrenic nerve injury (PNI) is a rare complication of catheter ablation therapy, most commonly observed in cryoablation of the right side pulmonary veins. We present a case of PNI after radiofrequency catheter ablation that developed acute dyspnea 24 hours after the intervention. Dyspnea is the main symptom of PNI, so the diagnosis should always be suspected if it appears after any type of catheter ablation involving the trajectory of the phrenic nerve. There is no specific treatment for PNI. The only maneuver that has been reported to accelerate the recovery of PNI is early stopping of the ablation therapy. Liliana E.

Coronary Artery Hematoma Treated with Fenestration Using a Novel NSE Alpha® Scoring Balloon Mon, 02 Oct 2017 05:52:59 +0000 http://www.hindawi.com/journals/cric/2017/8189530/ The optimal management of coronary intramural hematoma has not been defined. We described a case in which coronary occlusion developed due to an intramural hematoma after percutaneous coronary intervention for mid left circumflex artery (LCX). Intravascular ultrasound (IVUS) demonstrated the progression of the intramural hematoma and a totally compressed true lumen. Our approach was based on fenestration with a scoring balloon (NSE Alpha, Goodman, Japan), which allowed the deployment of an additional stent to be avoided. In conclusion, this management can be effectively and safely performed. Naohiro Funayama, Takao Konishi, Tadashi Yamamoto, and Daisuke Hotta Copyright © 2017 Naohiro Funayama et al.

Epoetin alfa is an erythrocyte-stimulating factor. We here present a case of an anemic patient, who was given epogen before a coronary artery bypass (CABG) surgery and developed periprocedural myocardial infarction. To our knowledge, there has been no previous case reported of epogen causing myocardial infarction. Case Presentation. 66-year-old female presented with substernal chest pain. EKG showed ST segment elevations in aVf and L-III. Patient underwent left heart catheterization (LHC) and had triple vessel disease. A bare metal stent was placed in RCA. Patient continued to have symptoms after discharge and presented to the ED again with these complaints. She underwent coronary artery bypass surgery (CABG). Before the procedure, patient’s hemoglobin was 11.1 grams/deciliter and was given epogen to raise hemoglobin level. Postoperative day (POD) #1 patient had ST elevations in inferior and anterolateral leads. She was diagnosed with periprocedural myocardial infarction. Patient underwent repeat LHC, which identified obstruction of saphenous vein graft (SVG). Hypercoagulable workup was negative for any disease and the patient was diagnosed with epogen induced early graft occlusion. Conclusion. Epogen administration can cause myocardial infarction and coronary artery thrombosis. We suggest that physicians use epogen very cautiously, especially in population who has underlying coronary artery disease.

Case Report of Multiembolic Cerebrovascular Event Associated with Ramp Study Echocardiogram Thu, 28 Sep 2017 08:43:45 +0000 http://www.hindawi.com/journals/cric/2017/9072523/ The incidence of ramp test echocardiogram-associated embolic events in the setting of therapeutic anticoagulation is likely rare and has not been reported. We present such a case in a patient with a HeartMate II left ventricular assist device (LVAD) whose serial head computed tomography images, deteriorating clinical course, and the multiembolic nature of the event suggest causality. If the pretest probability of pump thrombosis in an individual LVAD patient is sufficiently high, the potential risks of performing a ramp study echocardiogram may not be warranted, even in the setting of adequate anticoagulation.

Aorto-Right Ventricular Shunt after TAVR: Rare Complication of Common Procedure Thu, 28 Sep 2017 07:19:05 +0000 http://www.hindawi.com/journals/cric/2017/1834394/ Background. The primary treatment of symptomatic aortic stenosis is aortic valve replacement. Instead of open chest surgery, transcatheter aortic valve replacement (TAVR) is an alternative intervention for high-risk surgical candidates. Clinical Case. A 92-year-old male presented with progressive exertional dyspnea and recurrent syncopal attacks secondary to severe AS. The patient underwent successful transfemoral TAVR with 29 mm Edwards SAPIEN XT valve. His postoperative course was complicated by aorto-right ventricular shunt. The patient’s clinical course was followed up for one year. Conclusion. This case reports the incidence and clinical course of one of the rare complications of TAVR, aorto-right ventricular fistula. Conservative medical management is appropriate in hemodynamically stable patients with this specific complication.

A Rare Association of Takotsubo Cardiomyopathy with High-Degree Atrioventricular Block Wed, 20 Sep 2017 07:03:41 +0000 http://www.hindawi.com/journals/cric/2017/6989438/ Here we present a case of a patient who got trapped in an elevator; on initial evaluation patient was found with bradycardia; on further evaluation electrocardiogram (EKG) showed new onset 2nd-degree Mobitz type 2 AV block. On admission patient developed ischemic changes on EKG and troponin elevation. Transthoracic echocardiogram showed reduced ejection fraction as well as apical inferior, anterior, lateral, and septal hypokinesia. Coronary angiography showed nonobstructive coronary artery disease and ventriculogram demonstrated anterolateral and apical hypokinesia suggesting takotsubo cardiomyopathy (TCM). Atrioventricular block (AV) is rarely seen as initial presentation of TCM and has a prevalence of about 2.9%. AV block during early presentation of TCM poses a therapeutic dilemma with regard to the timing and the need to place a temporary or permanent pacemaker. The decision to place a permanent pacemaker may be on a case-by-case basis and more research is needed on formulating standardized recommendations in patients with TCM and conduction tissue abnormalities.

H. capsulatum: A Not-So-Benign Cause of Pericarditis Thu, 07 Sep 2017 07:54:27 +0000 http://www.hindawi.com/journals/cric/2017/3626917/ The common causes of pericarditis and its course are benign in the majority of cases. Thus, further testing is usually not pursued and treatment for a presumptive viral etiology with nonsteroidal agents and steroids has been an accepted strategy. We present a patient with pericarditis who was unresponsive to first-line therapy and was subsequently found to have necrotizing granulomas of the pericardium with extensive adhesions and fungal elements seen on tissue biopsy. Serologic testing confirms active H. capsulatum infection, and he responded well to Itraconazole treatment. In patients with pericarditis who fail standard therapy with NSAIDs and steroids, it is suggested that they undergo thorough evaluation and that histoplasmosis be considered as an etiology, especially in endemic regions.

Revascularization of Chronic Total Occlusion of the Infrarenal Aorta in a Patient with Triple Vessel Disease: Report of a Case Treated by Endovascular Approach Wed, 06 Sep 2017 10:03:45 +0000 http://www.hindawi.com/journals/cric/2017/7983748/ Surgical management of advance aortoiliac occlusive disease is time-tested and a widely practiced strategy, particularly when there is significant coronary artery disease associated with aortoiliac occlusive disease. The technological advances in the field of percutaneous techniques have facilitated the use of nonsurgical endovascular alternatives for peripheral arterial disease in patients with significant comorbidities at high surgical risk, as illustrated in our case report. We report a case of chronic total occlusion of the aorta that was treated percutaneously with endovascular stenting. We also discuss the specific technique used in this procedure.

Persistent Unexplained Dyspnea: A Case of Hepatopulmonary Syndrome Tue, 29 Aug 2017 00:00:00 +0000 http://www.hindawi.com/journals/cric/2017/1469893/ Regarding a patient with dyspnea, the history and physical examination often lead to the correct diagnosis. In some circumstances, when more than one underlying disease is present, the diagnostic process can be more challenging. We describe an unusual case of dyspnea and persistent hypoxemia related to a hepatopulmonary syndrome in a 53-year-old patient with known heart failure and chronic liver disease. Initially managed with intravenous diuretic therapy, due to signs of lung and peripheral congestion, our patient did not improve as expected; therefore we performed more advanced studies with a chest-abdomen CT scan and a right heart catheterization. They showed, respectively, no signs of parenchymal and vasculature lung disease, a cirrhotic liver disease, splenomegaly, signs of portal hypertension, and high cardiac output with normal pulmonary vascular resistance. These results, along with the association of hypoxemia and chronic liver disease, suggested a hepatopulmonary syndrome. The diagnosis was confirmed by the demonstration of an intrapulmonary vascular dilatation with right to left shunt during a microbubble transthoracic echocardiography and a lung perfusion scan. Liver transplantation is the only successful treatment for this syndrome; however, the patient became soon unsuitable for this strategy, due to a rapid clinical deterioration.

An Unusual Case of Recurrent Hypersensitivity Reaction Associated with Kounis-Like Acute Coronary Syndrome Sun, 27 Aug 2017 10:10:41 +0000 http://www.hindawi.com/journals/cric/2017/6421208/ There have been multiple reports of allergic reactions associated with acute coronary syndromes. This has been classically described as Kounis syndrome. We present an unusual case of 70-year-old male with multiple prior hypersensitivity reactions and history of coronary artery bypass grafting who presented recurrent episode of severe angioedema and anaphylaxis. He responded to epinephrine but subsequently developed a non-ST elevation myocardial infarction with worsening heart failure. Our case is unique in that, unlike classic Kounis syndrome, the acute coronary event in this case did not present concurrently with the allergic reaction; rather it took nearly 48 hours to present. Subsequent angiogram revealed patent grafts and significant decline in the left ventricular systolic function as compared to his own ECHO a year ago. We postulate that slow mediators of inflammation may play a role in delayed development of acute coronary events with associated LV dysfunction following episodes of angioedema and anaphylaxis.

An Incidentally Detected Right Ventricular Pseudoaneurysm Thu, 24 Aug 2017 06:46:58 +0000 http://www.hindawi.com/journals/cric/2017/4352474/ Ventricular pseudoaneurysm is an uncommon, potentially fatal complication that has been associated with myocardial infarction, cardiac surgery, chest trauma, and infectious processes. Diagnosis can be challenging, as cases are rare and slowly progressing and typically lack identifiable features on clinical presentation. As a result, advanced imaging techniques have become the hallmark of identification. Ahead, we describe a patient who presents with acute decompensated heart failure and was incidentally discovered to have a large right ventricular pseudoaneurysm that developed following previous traumatic anterior rib fracture.

Isolated Persistent Left Superior Vena Cava, Sick Sinus Syndrome, and Challenging Pacemaker Implantation Thu, 24 Aug 2017 00:00:00 +0000 http://www.hindawi.com/journals/cric/2017/9842524/ Persistent left superior vena cava with absent right superior vena cava is a very rare venous anomaly and is known as isolated PLSVC. It is usually an asymptomatic anomaly and is mostly detected during difficult central venous access or pacemaker implantation, though it could also be associated with an increased incidence of congenital heart disease, arrhythmias, and conduction disturbances. Herein, we describe a dual-chamber pacemaker implantation in a patient with isolated PLSVC and sick sinus syndrome. Hatice S.

Electromagnetic Interference from Swimming Pool Generator Current Causing Inappropriate ICD Discharges Wed, 23 Aug 2017 00:00:00 +0000 http://www.hindawi.com/journals/cric/2017/6714307/ Electromagnetic interference (EMI) includes any electromagnetic field signal that can be detected by device circuitry, with potentially serious consequences: incorrect sensing, pacing, device mode switching, and defibrillation. This is a unique case of extracardiac EMI by alternating current leakage from a submerged motor used to recycle chlorinated water, resulting in false rhythm detection and inappropriate ICD discharge. A 31-year-old female with arrhythmogenic right ventricular cardiomyopathy and Medtronic dual-chamber ICD placement presented after several inappropriate ICD shocks at the public swimming pool. Patient had never received prior shocks and device was appropriate at all regular follow-ups. Intracardiac electrograms revealed unique, high-frequency signals at exactly 120 msec suggestive of EMI from a strong external source of alternating current. Electrical artifact was incorrectly sensed as a ventricular arrhythmia which resulted in discharge. ICD parameters including sensing, pacing thresholds, and impedance were all normal suggesting against device malfunction. With device failure and intracardiac sources excluded, EMI was therefore strongly suspected. Avoidance of EMI source brought complete resolution with no further inappropriate shocks. After exclusion of intracardiac interference, device malfunction, and abnormal settings, extracardiac etiologies such as EMI must be thoughtfully considered and excluded. Elimination of inappropriate shocks is to “first, do no harm.” Edward Samuel Roberto, Thein Tun Aung, Atif Hassan, and Abdul Wase Copyright © 2017 Edward Samuel Roberto et al. All rights reserved. Chagas Cardiomyopathy Presenting as Symptomatic Bradycardia: An Underappreciated Emerging Public Health Problem in the United States Wed, 16 Aug 2017 06:31:22 +0000 http://www.hindawi.com/journals/cric/2017/5728742/ Chagas cardiomyopathy (CCM) is traditionally considered a disease restricted to areas of endemicity. However, an estimated 300,000 people living in the United States today have CCM, of which its majority is undiagnosed. We present a case of CCM acquired in an endemic area and detected in its early stage. A 42-year-old El Salvadoran woman presented with recurrent chest pain and syncopal episodes. Significant family history includes a sister in El Salvador who also began suffering similar episodes. Physical exam and ancillary studies were only remarkable for sinus bradycardia. The patient was diagnosed with symptomatic sinus bradycardia and a pacemaker was placed. During her hospital course, Chagas serology was ordered given the epidemiological context from which she came. With no other identifiable cause, CCM was the suspected etiology. This case highlights the underrecognized presence of Chagas in the United States and the economic and public health importance of its consideration in the etiological differential diagnosis of electrocardiographic changes among Latin American immigrants. While the United States is not considered an endemic area for Chagas disease, the influx of Latin American immigrants has created a new challenge to identify at-risk populations, diagnose suspected cases, and provide adequate treatment for this disease.

Spontaneous Coronary Artery Dissection: A Rare Manifestation of Alport Syndrome Mon, 14 Aug 2017 06:35:40 +0000 http://www.hindawi.com/journals/cric/2017/1705927/ Alport syndrome (AS) is a genetic disorder due to inheritance of genetic mutations which lead to production of abnormal type IV collagen. AS has been associated with renal, auditory, and ocular diseases due to the presence of abnormal alpha chains of type IV collagen in the glomerulus, cochlea, cornea, lens, and retina. The resulting disorder includes hereditary nephritis, corneal opacities, anterior lenticonus, fleck retinopathy, temporal retinal thinning, and sensorineural deafness. Aortic and aortic valve pathologies have been described as extrarenal manifestations of AS in multiple case reports. One case report described intramural hematoma of the coronary artery. We report the first case of true spontaneous coronary artery dissection (SCAD) with an intimal flap as a very rare manifestation of AS. The patient is a 36-year-old female with history of AS with chronic kidney disease, hypertension, and obesity who presented to the emergency room with acute onset of substernal chest pain radiating to her neck and arms. Troponin was elevated, and ECG showed transient 1 mm ST-segment elevation in the inferior leads. Subsequent coronary angiography revealed localized dissection of the left circumflex artery. Percutaneous coronary angioplasty was performed and her symptoms improved. This case illustrates that SCAD may be a manifestation of AS patients with chest pain.

The Use of a Novel Heart Failure Agent in the Treatment of Pregnancy-Associated Cardiomyopathy Mon, 14 Aug 2017 06:16:17 +0000 http://www.hindawi.com/journals/cric/2017/9561405/ Peripartum cardiomyopathy is an uncommon, pregnancy-related form of dilated cardiomyopathy that is associated with development of new-onset left ventricular dysfunction. Its etiology is presently unknown, but current standard of care involves the use of typical drug therapy for the treatment of heart failure. Pregnancy-associated cardiomyopathy (PACM) is a similar condition that refers to patients who develop such symptoms prior to the last month of pregnancy. We report the case of a nulliparous Caucasian female who develops early, severe PACM during her first pregnancy with postpartum persistence of New York Heart Association class II-III symptoms despite medical therapy. The use of the novel heart failure agent, sacubitril/valsartan (Entresto), is initiated with near-complete resolution of her symptoms. Vamsi C. Gaddipati, Aarti A. Patel, and Adam J.
