Abstract:
The patient was a 75-year-old man who presented to our hospital with complaints of palpitation and a cold sensation. Echocardiography revealed ventricular septal perforation(VSP) at the base of the posterior septum. As his hemodynamic condition was stable, patch closure of the VSP was performed on the 50th hospital day after fibrosis at the infarction site developed. Under cardiac arrest, an incision directed toward the cardiac apex was made at the base of the right ventricular inferior wall. Closure of the VSP was performed using double-patch sandwich technique:a bovine pericardial patch on the left, and a Dacron patch on the right ventricular side. The postoperative course was uneventful.
