Abstract
Surgical ventricular restoration with endoventricular patchplasty improves left ventricular function and restores left ventricular shape. The study included patients who presented with transmural anterior myocardial infarctions between June 2007 and May 2008. Briefly the technique included - coronary revascularization, resection of the endocardial scar, left ventricular reconstruction using an endoventricular synthetic patch. Left ventricular geometric parameters were studied preoperatively, early postoperatively, at 3 and 6 months and statistically analyzed by SPSS 14 software package. The ejection fraction increased from 33.5 ± 5.02 to 37.77 ± 7.17 immediate postoperatively. The preoperative left ventricular ejection fraction - a mean of 33.25% (±5.02%), increased by 10.3%-11% at the third and fourth follow up respectively after surgical ventricular restoration (p ≤ 0.001). The left ventricular end systolic volume index improved from a mean of 48.84 ± 11.37 preoperatively to 24.66 ± 5.92 postoperatively (p ≤ 0.001). Surgical ventricular restoration in our study has clearly demonstrated a positive effect on LV geometry.
