Surgical revascularization in patients with coronary artery disease and severe left ventricular dysfunction is a common practice and poses a surgical challenge. From September 2002 to May 2004, 50 patients (47 men and 3 women; mean age, 59 +/- 9 years) with a mean preoperative ejection fraction of 19.7% +/- 3.2% underwent surgical revascularization. The mean EuroSCORE was 7.2 +/- 3.4. Indications for surgery were congestive heart failure in 8 patients (16%), angina in 20 (40%), ventricular arrhythmias in 4 (8%), and critical left main stem disease in 12 (24%). Twenty-two patients (44%) had emergency surgery for critical anatomy and unstable symptoms. The number of grafts per patient was 3.7 +/- 0.8. Seventeen patients (34%) required intra-aortic balloon pump support, 16 (32%) needed pacing, and 48 (96%) had inotropic support postoperatively. Morbidity included re-operation for bleeding (2%), acute renal failure (10%), hemodialysis (4%), and fatal multiorgan failure (4%). Postoperative (4.9 +/- 3.7 months) 2-dimentional echocardiography was available in 18 patients of whom 11 (61%) showed improved left ventricular function (range, 5% to 45%). Thirty-day hospital mortality was 8%. These data indicate that surgical revascularization can be performed safely with acceptable hospital mortality in high-risk patients with severe left ventricular dysfunction. |
