ObjectiveTo analyze clinical outcomes of coronary artery bypass grafting (CABG) without concomitant surgical ventricular restoration (SVR) for patients with coronary artery disease (CHD) and left ventricular aneurysm (LVA). MethodsA total of 105 patients with CHD and LVA underwent surgical treatment in Wuhan Asia Heart Hospital from January 2008 to December 2012. Among them,74 patients were found to have no clear boundary LVA,poor wall motion or no obvious contradictory wall motion during surgical exploration,and didn't received SVR,including 59 male and 15 female patients with their age of 60.96±9.09 years. Coronary angiography showed 5 patients with single-vessel disease,10 patients with double-vessel disease,45 patients with triple-vessel disease,and 14 patients with left main and triple vessel disease. Intraoperative findings showed no clear boundary LVA in 30 patients,apical thinning without obvious LVA in 29 patients,LVA without obvious contradictory wall motion but thickening of the apex in 15 patients. All the 74 patients received CABG including 62 patients undergoing on-pump CABG and 12 patients undergoing off-pump CABG. Seventy patients received left internal mammary artery to left anterior descending anastomosis,and 2 patients received endarterectomy of the left anterior descending coronary artery. For moderate to severe mitral regurgitation,3 patients received concomitant mitral valvuloplasty,and 2 patients received concomitant mitral valve replacement. One patient received concomitant aortic valve replacement for severe aortic stenosis. ResultsPostoperatively,2 patients (2.7%) died of malignant arrhythmia and hypoxic ischemic encephalopathy respectively. Six patients received intra-aortic balloon pump (IABP) support for low cardiac output syndrome,perioperative myocardial infarction and malignant arrhythmias. Seventy patients were followed up after discharge for 24-60 (43±12) months. During follow-up,left ventricular thrombus was found in 8 patients,disappeared within 1 year after warfarin treatment in 5 patients,and no thromboembolic event happened. Echocardiogram showed that LVA disappeared in 18 patients (25.7%). Ejection fraction (EF) at discharge,6 months and 1 years after discharge were significantly higher than preoperative EF (EF at 6 months after discharge versus preoperative EF:44%±6% vs. 39%±5%). Left ventricular end-diastolic diameter (LVEDD,LVEDD at 6 months after discharge versus preoperative LVEDD:54.37±6.28 mm vs. 59.24±6.24 mm) and left ventricular end-systolic diameter (LVESD) were significantly reduced compared with preoperative values (P<0.01). But as time went by,LVEDD and LVESD gradually became larger than those values at discharge. ConclusionFor patients with CHD and LVA,CABG without SVR,which is decided according to actual surgical exploration,can significantly improve postoperative EF,LVEDD and LVESD,but left ventricular enlargement may happen progressively after discharge.
