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

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 …

OBJECTIVES We sought to determine the prevalence and rate of progression of left
ventricular outflow tract obstruction (LVOTO) and aortic regurgitation (AR) in adults with …

Background: Recurrence after surgical resection of discrete subvalvar aortic stenosis in
children often requires repeat operation. Risk factors for recurrence are poorly understood …

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

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

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

Subvalvular aortic stenosis accounts for 1–2% of all congenital heart disease and for 8–20%
of cases of left-ventricular outflow tract (LVOT) obstruction in children. Recurrence of …

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 …

Aims Discrete subaortic stenosis (DSS) is often diagnosed early in life and known for its
sometimes rapid haemodynamic progression in childhood and strong association with aortic …
