A Modified Transatrial Approach for Repair of Postinfarction Ventricular Septal Defect.

Abstract

Ventricular septal defect (VSD) is a life-threatening complication of myocardial infarction. Surgical repair is generally performed through a left/right ventriculotomy. To avoid complications associated with ventriculotomy, a right transatrial approach has been proposed. We describe a modified transatrial approach through the left atrium for basal-inferior VSD. After left atriotomy, mitral valve is detached from the annulus to expose the defect, which is closed with a pericardial patch. Two patients were operated by this method. In both cases venoarterial extracorporeal membrane oxygenation with a ventricular vent was utilized to unload the left ventricle. Echocardiography revealed no residual shunt in both cases.
