Combined valve replacement and myocardial revascularization.
Combining valve replacement with coronary artery bypass (CABG) for significant concomitant disease remains a controversial subject. To determine the operative results following combined valve replacement and CABG, we evaluated 201 patients seen consecutively between July 1977 and June 1982. CABG for vessels with greater than 70% stenosis was performed with aortic valve replacement in 106 patients, with mitral valve replacement in 82, and with aortic and mitral valve replacement in 13. There were 143 men and 58 women; the mean age was 67 years. Nine operative deaths (8.5%) occurred with aortic valve replacement and CABG: 5 of 25 (20%) when cardioplegia was not used and 4 of 81 (4.9%) with cardioplegia (p less than 0.01). The operative mortality rate for isolated aortic valve replacement without coronary disease during the same period was 5.9% (10 of 168). The late actuarial survival rate is similar for aortic valve replacement alone or aortic valve replacement and CABG. There were no operative deaths among patients having undergone aortic and mitral valve replacement and CABG; the rate was 15% (9 of 60) in patients having undergone aortic and mitral replacement and CABG. The operative mortality rate was 21.9% for mitral valve replacement and CABG (18 of 82). Rheumatic disease was present in 14 of these patients, two of whom had early deaths (14.3%), both after repeat mitral operations; 11 mitral valve replacements and CABG were done for degenerative mitral regurgitation with no deaths, and the remaining 57 patients had ischemic mitral regurgitation.(ABSTRACT TRUNCATED AT 250 WORDS)
