Abstract:
We report a case in which the double-patch technique was used to repair residual shunt after infarct exclusion technique for post-infarction ventricular septal perforation (VSP). A 68-year-old man was diagnosed with post-infarction VSP and surgical interveniton was performed by infarct exclusion technique through left ventriculotomy. Residual shunt was observed by left ventriculography, and he developed cardiac failure in spite of medical therapy. Additional surgery for residual shunt was performed 5 months after the initial operation. The VSP was closed with 2 pericardial patches onto both sides of the septum through right ventriculotomy. Complete closure of the defect was accomplished, and no residual shunt was observed by post-operative left ventriculography. The patient has been doing well with no signs of cardiac failure.
