Hammock mitral valve: A rare case report

Abstract

Congenital mitral stenosis is a relatively rare disorder comprising 0.2% of all congenital heart defects. Hammock mitral valve producing severe mitral stenosis is a rare variant of congenital mitral stenosis. We report a 2-year-old boy who had hammock mitral valve producing severe mitral stenosis with severe pulmonary artery hypertension. He underwent successful surgical repair. Post-surgery, the mitral valve opening was adequate without residual stenosis or regurgitation. Pulmonary artery pressure had normalized. Follow-up data showed he had significant clinical and echocardiography improvement. This is the first reported case of successful surgical repair done for hammock mitral valve from our institute.
