Hammock Mitral Valve Repair in Infancy: Operative Steps Toward a Customized Reconstruction After Preoperative Planning.

Hammock mitral valve (MV) repair is historically technically difficult with a guarded prognosis. Surgical experience is extremely limited and variable outcomes are reported. The perioperative strategy and technical details of hammock MV repair in an infant who presented with severe mitral stenosis are described and review of the existing literature was undertaken.

The Challenge of Hammock Mitral Valve During Infancy: Precise Preoperative Advanced Imaging and Three-Dimensional Modeling Augments Customized Operative Valve Reconstruction.

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.

Damus-Kaye-Stansel procedure 5 years after Fontan operation with ligated main pulmonary artery.

We report a case of tricuspid atresia with transposed great arteries and rudimentary right ventricle owing to which the patient developed severe subaortic stenosis and restrictive bulboventricular foramen 5 years after her extracardiac Fontan operation. She underwent a successful modified Damus-Kaye-Stansel operation using her native pulmonary valve. Spiral cardiac computed tomography with three-dimensional reconstructions was instrumental in pre-operative surgical planning.

Reimplantation of anomalous single coronary artery from pulmonary artery: diagnosis and surgical management.

A newborn presented in cardiogenic shock with the diagnosis of anomalous single coronary artery from pulmonary artery and was successfully revived with prostaglandin (PGE1) infusion. She underwent surgical implantation of her coronary arteries while receiving PGE1 infusion to maintain high oxygen tension for the coronaries during cardiopulmonary bypass. She was discharged in 2 weeks with good biventricular function and moderate mitral regurgitation.

Surgical strategies and outcomes in patients with Shone complex: a retrospective review.

Background: Multilevel obstruction of left-sided heart structures was originally characterized by Shone and colleagues. The formulation of an appropriate operative strategy remains problematic. Surgical outcomes have generally been poor.
