A 71-year old-man presented with 4 posturally related syncopal episodes. He carried a diagnosis of asymptomatic hypertrophic cardiomyopathy (HCM) without obstruction based on an echocardiogram 7 years earlier. Echocardiography at the time of syncope evaluation demonstrated a hyperdynamic left ventricle with a septal thickness of 20 mm (an increase of 4 mm from an earlier echocardiogram), newly ...

Our understanding of hypertrophic cardiomyopathy (HCM) as a disease entity has increased dramatically over the last half century. There has been a concerted effort by several surgical groups to develop operative techniques to relieve left ventricular outflow tract (LVOT) obstruction and alleviate symptoms. This paper traces the development of transaortic septal myectomy, the current gold standa...

Mitral endocarditis complicating hypertrophic cardiomyopathy occurs predominantly on the left ventricular aspect of the anterior mitral valve leaflet in the presence of outflow tract obstruction. It is a rare condition and the estimated cumulative 10 year probability of developing endocarditis in patients with obstruction is < 5%. Combined mitral valve replacement and septal myectomy has been r...

LEOPARD syndrome is an autosomal dominant genetic disorder involving a complex of malformations and other features, including lentiginosis, electrocardiographic conduction abnormalities, ocular hypertelorism, pulmonary valve stenosis, abnormal genitalia, growth retardation, and sensorineural deafness. The most common cardiovascular manifestations of this condition are pulmonary valve stenosis, ...

Cross-sectional echocardiographic (CSE) studies were obtained in 29 children with tetralogy of Fallot. In this study we evaluated the capability of CSE to record the right ventricular outflow tract (RVOT) and compared the severity of infundibular obstruction determined by CSE with cineangiographic (cine) determinations. In addition, we examined capabilities of CSE and M-mode echocardiography (M...

Hypertrophic cardiomyopathy (HCM) is a highly heterogeneous disease with varied patterns of hypertrophy. Basal septal hypertrophy and systolic anterior motion (SAM) of the mitral valve (MV) are the key pathophysiological components to left ventricular outflow tract (LVOT) obstruction in HCM. LVOT is associated with higher morbidity and mortality in patients with HCM. Percutaneous septal reducti...

Objectives: Congenital heart disease or CHD is a condition that affects 8 out of every 1,000 newborns. Every year more than 35,000 newborns are diagnosed with a congenital heart disease in the United States. Neonates and children with congenital heart disease are at increased risk for thrombotic events, especially those with a single ventricle physiology. The objective of this study was to asse...

Obstructive Hypertrophic Cardiomyopathy: Pathogenesis of the Obstruction In most patients, the hypertrophy develops initially in the septum and extends to the free walls, often giving a picture of concentric hypertrophy. In '25% of patients with familial hypertrophic cardiomyopathy (FHCM), asymmetrical septal hypertrophy leads to a highly variable pressure gradient between the apical left ventr...

Forty-one children with transposition of the great arteries, ventricular septal defect, and left ventricular outflow tract obstruction underwent a Rastelli operation between 1971 and 1978. A homograft valve preserved in an antibiotic solution and extended with A dacron tube was the conduit of choice. Alternatively, conduits with porcine heterografts or valves constructed from calf pericardium w...
