Surgery for Ventricular Septal Defect following Acute Myocardial Infarction with Special Reference to Operative Procedure / 日本心臓血管外科学会雑誌

ABSTRACT

Nine patients underwent surgical repair of ventricular septal defect (VSP) following acute myocardial infarction in our hospital during the past 5 years. Sites of perforation were apex ventricular septum (A-VSP) in five, high anterior ventricular septum (H-VSP) in one and posterior ventricular septum (P-VSP) in three. A-VSPs were closed by single patch on the left ventricular side of the septum. H-VSP was closed by double patch and ventriculotomy was closed directly. For P-VSPs, three different operative procedures were performed. Patch closure of VSP and reconstruction of free ventricular wall was done in one, while in other two VSP was closed by single patch on the left or right side of the septum. There were two operative deaths, one A-VSP and one P-VSP. We think that patch closure through right ventriculotomy is useful in cases of small P-VSP.
