Arrhythmogenic right ventricular cardiomyopathy, a genetically inherited disease that results in fibrofatty replacement of normal cardiac myocytes, has been associated with sudden cardiac death in athletes. Long-term participation in endurance exercise hastens the development of both the arrhythmic and structural arrhythmogenic right ventricular cardiomyopathy phenotypes. We describe the unusual case of a 34-year-old, symptomatic, female endurance athlete who had arrhythmogenic right ventricular cardiomyopathy in the presence of a structurally normal right ventricle...

Isolated supravalvular aortic stenosis in adults is a rare form of left ventricular outflow tract obstruction. We describe a case in a 41-year-old man in whom the supravalvular aorta had narrowed to approximately the size of the left anterior descending coronary artery. The patient underwent aortic surgery with replacement of the ascending aorta and repair of supravalvular aortic stenosis with a pantaloon graft. A postoperative echocardiogram showed substantial improvement: the mean gradient across the aorta had fallen from 48 to 8 mmHg...

Invasion of a renal cell carcinoma thrombus into the inferior vena cava and right atrium is infrequent. Reaching and completely excising a tumor from the inferior vena cava is particularly challenging because the liver covers the surgical field. We report the case of a 61-year-old man who underwent surgery for a renal cell carcinoma of the right kidney that extended into the inferior vena cava and right atrium. During dissection of the liver to expose the inferior vena cava, transesophageal echocardiograms revealed right atrial mass migration into the tricuspid valve...

Mycotic aneurysm after bacteremia is a rare diagnosis in children and adolescents. We report the case of a previously healthy adolescent who presented with chest pain and fever and who developed a mycotic aneurysm of the aorta after contracting community-acquired, methicillin-resistant Staphylococcus aureus. Early recognition of widening of the patient's superior mediastinum, noted during a comparison of the patient's initial and follow-up chest radiographs, prompted computed tomographic angiography of the chest and led to a timely diagnosis, rapid surgical intervention, and a good clinical outcome...

Transcatheter aortic valve replacement is an established option for treating patients with symptomatic aortic stenosis; however, severe, life-threatening complications, such as valve migration, are possible. We report the case of an 82-year-old woman whose Edwards Sapien XT valve migrated into the left ventricular outflow tract one day after transcatheter aortic valve replacement. We used an inflated balloon to adjust the position of the migrated valve before performing a valve-in-valve procedure via a transapical approach, which resulted in a good valve implantation...

We describe the case of a 57-year-old man who had severe mitral valve stenosis and regurgitation without significant annular calcification. He was not a candidate for surgical valve replacement or repair because of his substantial comorbid conditions, overall frailty, and elevated surgical risk. He underwent successful transcatheter mitral valve replacement of his native mitral valve with compassionate, off-label use of an Edwards Sapien 3 valve. A search of the literature produced no other cases like ours, which represents a further evolution of the transcatheter valve implantation concept...

Thrombus formation after stent deployment has been linked to the use of heparin and of antithrombotic agents, such as bivalirudin, during percutaneous coronary intervention. Fluoroscopy has been used to identify stent thrombosis, typically after patients become symptomatic. We describe our use of optical coherence tomography to diagnose and evaluate intraprocedural stent thrombosis in a 68-year-old man who was given bivalirudin just before a percutaneous coronary procedure. This imaging method enabled immediate therapeutic intervention...

Isolated ventricular noncompaction, a rare genetic cardiomyopathy, is thought to be caused by the arrest of normal myocardial morphogenesis. It is characterized by prominent, excessive trabeculation in a ventricular wall segment and deep intertrabecular recesses perfused from the ventricular cavity. The condition can present with heart failure, systematic embolic events, and ventricular arrhythmias. Two-dimensional echocardiography is the typical diagnostic method. We report a case of heart failure in a 35-year-old man who presented with palpitations...

Using cardiac magnetic resonance, we tested whether a single-breath-hold approach to cardiac functional evaluation was equivalent to the established multiple-breath-hold method. We examined 39 healthy volunteers (mean age, 31.9 ± 11.4 yr; 22 men) by using 1.5 T with multiple breath-holds and our proposed single breath-hold. Left ventricular and right ventricular ejection fractions (LVEF and RVEF), LV and RV end-diastolic volumes (LVEDV and RVEDV), and LV myocardial mass (LVMM) were compared by using Bland-Altman plots; LVEF and RVEF were tested for equivalence by inclusion of 95% confidence intervals (CIs)...

Selecting an appropriate surgical approach for double-outlet right ventricle (DORV), a complex congenital cardiac malformation with many anatomic variations, is difficult. Therefore, we determined the feasibility of using an echocardiographic classification system, which describes the anatomic variations in more precise terms than the current system does, to determine whether it could help direct surgical plans. Our system includes 8 DORV subtypes, categorized according to 3 factors: the relative positions of the great arteries (normal or abnormal), the relationship between the great arteries and the ventricular septal defect (committed or noncommitted), and the presence or absence of right ventricular outflow tract obstruction (RVOTO)...

No clinical risk score is universally accepted for coronary artery disease. In 603 patients (mean age, 61.2 ± 12.3 yr) with stable coronary artery disease, we investigated the predictive power of clinical risk scores derived from the Framingham, the Long-term Intervention with Pravastatin in Ischemic Disease (LIPID), and the Vienna and Ludwigshafen Coronary Artery Disease (VILCAD) studies. Secondary outcomes were the recurrence of an acute thrombotic event (coronary events, strokes, or transient ischemic attacks), or heart failure or death...

Implanted cardioverter-defibrillators can prevent sudden cardiac death in at-risk patients. In comparison with conventional transvenous systems, entirely subcutaneous implantable cardioverter-defibrillators have produced similar reductions in the rate of sudden cardiac death but with fewer sequelae. An infrequently reported drawback of subcutaneous devices, however, is the potential for generating attenuation artifact during nuclear myocardial perfusion imaging. We had concerns about potential attenuation artifact in a 65-year-old man with coronary artery disease but found that having positioned the pulse generator in the midaxillary zone avoided problems...

Reactive eosinophilia is associated with inflammatory bowel disease, but its association with eosinophilic myocarditis is rare. We report a case of a 42-year-old man who presented with hypovolemic shock secondary to diarrhea and recently diagnosed nonischemic cardiomyopathy (left ventricular ejection fraction, 0.29). Laboratory evaluation revealed marked peripheral eosinophilia. Cardiac magnetic resonance imaging showed evidence of subacute-to-chronic myocarditis, and endomyocardial biopsy results were consistent with eosinophilic myocarditis...
