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: 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 …

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

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

INTRODUCTION: Subaortic stenosis is a rare congenital heart disease defined as a left
ventricular outflow tract obstruction. We reviewed our surgical experience in this cardiac …

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 …

Objectives. We sought to determine whether early resection can improve outcome in fixed
subaortic stenosis. Background. The diagnosis of subaortic stenosis (SAS) is often made …

Subaortic stenosis is typically thought to be a simple disease—resect the subaortic
membrane and the patient is cured. While many patients indeed are ''cured''by a surgical …

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

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 …
