Subvalvular aortic stenosis (SAS) is one of the common adult congenital heart diseases,
with a prevalence of 6.5%. It is usually diagnosed in the first decade of life …

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

Background—Discrete subaortic stenosis is notable for its unpredictable hemodynamic
progression in childhood and high reoperation rate; however, data about adulthood are …

BACKGROUND: We sought to determine the prevalence of intervention and associated
factors in children presenting with subaortic stenosis. We also investigated whether a …

OBJECTIVE: Substantial controversy persists regarding the need and efficacy of a routine
myectomy in the treatment of discrete subaortic stenosis. Although some believe myectomy …

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 …

Purpose Discrete subaortic stenosis (DSS) is a left-ventricular outflow tract (LVOT)
obstruction caused by a membranous lesion. DSS is associated with steep aortoseptal …

1448 Circulation April 9, 2013 often rather symmetrical and forms as robustly in the outflow

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

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 …
