Abstract:
Objective To summarize the clinical experience of coronary angiography before coronary artery grafting (CABG) with concomitant valvular surgery in patients with valvlar disease. Methods From April 2000 to May 2005, two hundred and eleven patients over 50 years old (mean age 60 3.5) with valvlar diseases were studied retrospectively. Coronary angiography was utilized for patients who were found to have risk factors for atherosclerosis. Coronary stenosis over 50% of its calibre was considered positive, and 75% stenosis (including LMCA stenosis more than 50%) was used as the indication for coronary artery bypass surgery. Results Coronary angiography was employed in 128 patients and 30 cases (23.4%) had coronary artery stenosis exceeding 50%. CABG was concomitantly performed during cardiac valvular surgery in 24 patients. In-hospital mortality in patients with valve surgery alone was 0.5%, which was significantly lower compared with patients with valve surgery combined with CABG group (4.2%)(P
