Medium-term outcomes of a modified technique for RSOV-VSD subset.

Abstract

Rupture of sinus of Valsalva (RSOV) aneurysm to right ventricular outflow tract or main pulmonary artery is commonly associated with subaortic ventricular septal defect (VSD). A standard surgical approach described is double patch closure. We have adopted the principle of transaortic direct closure of VSD with prosthetic patch closure of sinus defect; this novel technique is used for past 15years with good long-term results. We believe this technique appropriately addresses the embryo-pathological basis of RSOV-VSD complex.
