ABSTRACT:
The symptoms of congenital heart failure are addressed in this surgical procedure for mounting a patch in the ventricle of the heart to reduce ventricular volume. Placement of the patch is facilitated by palpating a beating heart to identify akinetic, although normal appearing, tissue. The patch has an oval configuration facilitating return of the heart to a normal apical shape which enhances muscle fiber efficiency and a normal writhing pumping action. The patch includes a semi-rigid ring, and a circumferential rim to address bleeding. Patch placement is further enhanced by creating a Fontan neck and use of pledged sutures. Intraoperative vascularization and valve replacement is easily accommodated. Increased injection fraction, reduced muscle stress, improved myocardial protection, and ease of accurate patch placement are all achieved with this procedure.
