Late Presentation of Left Ventricular Outflow Tract Obstruction due to Sub-aortic Membrane

Abstract

Left Ventricular Outflow Tract (LVOT) obstruction is caused by a wide range of different anatomical lesions referred to as Sub-aortic Stenosis (SS). SS can be isolated or associated with other heart defects; and tends to evolve and progress over time even though the speed of its progression is very variable and difficult to predict. We present a case of a patient affected by sub-aortic mem2.
