Long Term Results With the Cabrol Aortic Root Replacement

Abstract

Cabrol aortic root replacement is rarely performed in recent years because of potential coronary complications. The purpose of this study was to investigate its early and late results, including coronary complications, by evaluating our experience thus far. A retrospective lookup of patients who underwent Cabrol aortic root replacement between 1988 and 2001 found a total of 36 patients (24 men and 12 women) with a mean age of 45 years. Annuloaortic ectasia was the most frequent cause (n = 22), followed by chronic dissection (n = 5), acute dissection (n = 5), and aneurysm with prior aortic operation (n = 4). Early mortality occurred in one patient (2.8%). The mean follow-up period was 104 months. There were 7 late deaths, 4 of which were disease-related. The actuarial survival was 83.3% at 5 years and 72.9% at 10 years, and the freedom from reoperation was 87.9% at 5 years and 76.6% at 10 years. There were no reoperations on the ascending aorta. Coronary ostia were examined by angiography or 64-row multidetector computed tomography in 18 patients 43 to 189 months after the operation. Two patients developed stenosis or occlusion of the right coronary ostium. The early and late results of the Cabrol operation were favorable with the exception of coronary complications. The importance of careful follow-up for late coronary complications cannot be overemphasized.
