Hammock mitral valve: a rare cause of congenital mitral regurgitation--a case report

Gopalan Nair Rajesh et al. Indian Heart J. 2014 May-Jun.

Abstract

Hammock valve, also known as anomalous mitral arcade is a rare mechanism for congenital mitral insufficiency. We report a case of a two-week-old neonate who presented with features of heart failure and an apical systolic murmur. Echocardiogram showed severe mitral regurgitation and abnormal mitral valve with direct attachment of mitral leaflets to papillary muscle without intervening chordae tendinae, typical of hammock valve. Heart failure was controlled with ionotrpes and diuretics. The literature on the hammock mitral valve is reviewed.

Keywords: Congenital; Hammock valve; Mitral regurgitation; Mitral valve.
