[Preservation of the aortic valve in acute dissection of the ascending aorta].
The aim of this study was to evaluate the status of the native aortic valve in patients operated for acute dissection of the ascending. aorta (ADAA). Between November 1972 and November 1991, 93 patients were operated for ADAA. There were 76 men and 17 women (average age 54 +/- 12 years). The aortic valve was reserved in 80 cases (86%). In 13 patients (14%) aortic valve replacement was associated with replacement of the ascending aorta. The early mortality was 29% (27/93). The global actuarial survival rates at 5, 10 and 15 years were 60.2 +/- 5.2%, 49.7 +/- 6.1% and 26.9 +/- 9.9% respectively. Fifty patients (94%) in whom the native aortic valve was preserved were followed up. Nine patients (18%) died and average of 97 +/- 46 months after surgery. The causes of death were aortic rupture or extension of the dissection (N = 4), ischemic cardiac failure (N = 2), renal failure (N = 1), cerebrovascular accident (N = 1) and sudden death (N = 1). Forty one patients underwent transthoracic echocardiography. Seven patients developed severe aortic regurgitation, 6 of whom had to be reoperated for aortic valve replacement. Echocardiography showed absence of of minimal aortic regurgitation in 22 cases and mild aortic regurgitation with normal left ventricular function in 12 cases (in 2 cases, aortic valve replacement was associated with surgical treatment of another valvular lesion or of coronary artery disease). Therefore, aortic valve replacement was performed in 8 patients 61.5 +/- 51.2 months after the initial operation.(ABSTRACT TRUNCATED AT 250 WORDS)
