Hammock mitral valve (MV), also known as anomalous mitral arcade, is a rare congenital anomaly. We report a case of a 10-month-old child who presented with congestive heart failure and was found to have severe mitral stenosis (MS) secondary to a hammock MV anomaly. Detailed advanced imaging with cardiac MRI and three-dimensional (3D) echocardiography favorably navigated a customized valve-sparing surgical reconstruction of the congenitally abnormal MV. Repair of a hammock MV is technically difficult with a guarded prognosis. Surgical experience is extremely limited and variable outcomes are reported. A rare case of severe MS secondary to hammock MV deformity with successful surgical repair and review of worldwide literature are presented.
