Background: Congenital subaortic stenosis entails a lesion spectrum, ranging from an
isolated obstructive membrane, to complex tunnel narrowing of the left outflow associated …

Objective: The term “subaortic stenosis” includes a variety of obstructions of the left
ventricular outflow tract (LVOT), ranging from a short (discrete) subvalvular membrane to …

Objective: The aim of the study was to analyze the long-term results of congenital subvalvar
aortic stenosis (SAS) relief and the risk factors associated with recurrence and reoperations …

Abstract Background/Objective: Secondary subaortic stenosis (SSS) can occur after surgery
for various congenital heart defects with or without initial left ventricular outflow tract …

OBJECTIVE To document the natural history and surgical outcomes for discrete subaortic
stenosis in children. DESIGN Retrospective review. SETTING Tertiary care paediatric …

In a 4-year period from July 1984 to July 1988, 21 children required surgical treatment for
subaortic stenosis. Age at operation ranged from 12 months to 17 years (mean, 7.3±4.8 …

Although mortality following repair of subaortic obstruction is low, aggressive resection may
increase morbidity. We sought to evaluate outcomes and risk of atrioventricular heart block …

Background. Congenital subaortic stenosis (SAS) has a high recurrence rate after surgical
correction. Aortic valve disease frequently coexists with SAS, being its occurrence and …

Background: Studies of long-term outcomes of discrete subaortic stenosis (DSS) are rare.
Therefore, we reviewed the long-term outcomes of subaortic membrane resection in children …

Subaortic stenosis carries considerable morbidity and mortality. In most cases, patients have
an underlying left ventricular outflow tract morphology that promotes turbulence at the …
