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.
吊床样二尖瓣（MV），也称为二尖瓣弓异常，是一种罕见的先天性异常。我们报告一例10个月大的儿童，表现为充血性心力衰竭，经检查发现因吊床样MV异常继发严重二尖瓣狭窄（MS）。心脏磁共振成像（MRI）和三维（3D）超声心动图等详细的高级成像技术成功地指导了对先天性异常MV进行定制的保留瓣膜手术重建。修复吊床样MV技术难度大，预后不佳。手术经验极其有限，报道的结果也各不相同。本文介绍了一例因吊床样MV畸形继发严重MS并成功进行手术修复的罕见病例以及对全球文献的综述。
