Shone's syndrome

Introduction

Overview

Overview

Shone’s syndrome consists of a set of four cardiac defects: a supravalve mitral membrane (SVMM), parachute mitral valve, subaortic stenosis (membranous or muscular) and coarctation of the aorta. Essentially, it is both a left ventricular inflow and outflow obstruction. The prognosis is inversely related to the degree of obstruction caused by the SVMM.[1] The SVMM is also first to develop and likely causes the development of the other three defects.
