How to repair the defects in post myocardial ?

Repair of Defect :  The approach to the defect is through ventriculotomy over the infarcted area. The defect is repaired using a collagen or gelatin impregnated Dacron patch. The muscle around the defect is usually very friable and holds sutures poorly. In one of the techniques, interrupted pledgetted sutures are passed away from the margins of the defect and infarcted muscle. The sutures are passed from the light ventricular aspect with the pledgets positioned on the right ventricular side of the septum. When all sutures are taken they are passed through a large Dacron patch and is lowered to the left velltricular aspect of septum and tied.

In a similar technique two circular patches are used-one on the right ventlicular aspect, and the second one on the left ventricular side of the septum. After repair, left ventriculotomy is closed with two strips of Teflon felt for reinforcement of the suture line.
