摘要: To test the hypothesis that coronary artery bypass grafting (CABG) is not routinely required in patients undergoing aortic valve replacement (AVR) who have coexistent disease (CAD), we compared results of operation 55 consecutive symptomatic had CAD and underwent AVR without CABG with another 142 during same period, published from other centers which was used AVR. Operative mortality 4% 5% CAD. Late survival significantly different between two groups when analyzed for entire population (80% at 3 years patients, 82% non-CAD patients), or subgroup stenosis, regurgitation stenosis plus regurgitation. Eight (15%) developed recurrent angina after (mean follow-up 43 months); only three (6%) because medically refractory (12-43 months). mortality, operative infarction (9%), long-term were similar to those CABG. These data suggest preoperative detection does necessitate all time
