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

Background: We sought to determine the long-term rate of progression of left ventricular
outflow tract (LVOT) obstruction and aortic insufficiency (AI) in adult patients operated on for …

BACKGROUND: The association between discrete subaortic stenosis and other subaortic
anomalies is a well known but rarely reported occurrence. The aim of this study is to define …

Objectives: Discrete subaortic stenosis causes left ventricular outflow tract (LVOT)
obstruction and often produces aortic regurgitation (AR) which alone may precipitate …

Although recommended by several investigators, the benefit of early surgery in patients with
fixed subaortic stenosis has not been proved. Findings were reviewed of 57 patients with …

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 aim of the study was to analyze the long-term results of subaortic stenosis
relief and the risk factors associated with recurrence and reoperation. Methods: One …

BACKGROUND: Subaortic stenosis (SAS) is a curtain of tissue involving the subaortic
region, the aortic and mitral valves, the septum, and the fibrous trigones. Little is known of its …

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 …
