Abstract
A 50-year-old man was diagnosed as having aortic valve insufficiency, complete occlusion of the right coronary artery and 75% stenosis of the left main trunk due to syphilitic aortitis. Aortic valve replacement and coronary artery bypass grafting to three vessels were successfully performed. The selection of surgical procedures for the coronary lesion with syphilitic aortitis should be made carefully, since the progression of aortic root inflammation in the acute phase and the development of atherosclerotic changes are not preventable in the future. It is most important to select effective and safe surgical interventions, especially for patients with such a low cardiac function as our patient.
