Abstract
We evaluated 4 patients who had undergone previous cardiac surgery underwent reoperation involving aortic root replacement. Subjects were a 55-year-old man who had undergone separate valve graft replacement for a dissecting aneurysm (DeBakey type I) 3.25 years earlier; a 51-year-old woman who had undergone separate valve graft replacement for a dissecting aneurysm (DeBakey type I) 6 years earlier; a 66-year-old woman who had undergone aortic valve replacement and single coronary artery bypass grafting for severe aortic regurgitation, angina pectoris, and aortitis syndrome 11 years earlier; a 47-year-old man who had undergone mitral valve replacement and 3-coronary artery bypass grafting for severe mitral regurgitation and angina pectoris 4 years earlier. Development of a surgical technique, coupled with myocardial protection, and pharmacological treatment at reoperation yielded excellent early surgical results To reduce the incidence of reoperation and ensure satisfactory long-term results, we recommend radical management for the individual case be selected at initial operation and entire resections be conducted for aneurysmal degeneration or dissected segments.
