Sandwich technique via right ventricle incision to repair postinfarction ventricular septal defect.

Abstract

We describe two cases where postinfarction ventricular septal defect (VSD) was treated with a new technique. Application of direct ultrasonography to the right ventricular (RV) wall enables the surgeon to visualize the region and perform appropriate incision into the right ventricle and trabecula resection. The VSD is sealed with gelatin-resorcin-formal (GRF) glue between two patches, one placed on the left ventricular side and the other on the right ventricular side. RV incision provides easy bleeding control and the "sandwich technique" using two patches and GRF sealing provides geometric preservation of the left ventricular shape and prevents residual shunt.
