Discrete subaortic stenosis typically appears as a well-defined membrane beneath the aortic
valve. To assess the merits of alternative approaches to this problem, we have reviewed the …

Background Supravalvular aortic stenosis (SVAS) represents a heterogeneous group,
including Williams syndrome, familial elastin arteriopathy, sporadic cases, and others. This …

Background The common causes of subaortic left ventricular outflow tract obstruction
(LVOTO) are hypertrophic cardiomyopathy (HCM) and membranous/tunnel subaortic …

Objective Contemporary outcomes data for complete atrioventricular septal defect (CAVSD)
repair are limited. We sought to describe early outcomes of CAVSD repair across a large …

Summary 168 patients with flxed subaortic Stenosis (fixed SAS) were studied between 1959
and 1987. For assessment of the long term prognosis, the hemodynamic results of the …

Background The purpose of this study was to compare the modified single‐patch technique
with the two‐patch technique for infants with complete atrioventricular septal defects …

We reviewed the surgical outcomes in adults and children with subaortic stenosis and intact
ventricular septum in the current era. The case notes of 50 patients were reviewed for …

Surgical and nonsurgical patients with isolated subaortic stenosis (SAS) were compared to
determine the important factors contributing to the timing of surgical intervention. This study …

Background. Narrowing of the left ventricular outflow tract has been associated with partial
atrioventricular septal defect (PAVSD) in about 3% of patients. Because of the predisposing …

OBJECTIVES Percardiac device closure of ventricular septal defects (VSDs) is considered
as an alternative to surgical repair in certain patients; however, the safety and validity of this …
