Abstract

BACKGROUND:

This study evaluated effectiveness of three different surgical strategies for treating ascending aorta aneurysm, with or without involvement of the aortic root, associated with bicuspid aortic valve (BAV).

METHODS:

Between 2005 and 2011, 150 consecutive patients underwent a Bentall operation in the presence of ascending aorta and aortic root dilation exceeding 45 mm in diameter and malfunctioning BAV (n = 46, group 1); separate aortic valve and ascending aorta replacement in presence of ascending aorta dilation exceeding 45 mm, aortic root of less than 45 mm, and malfunctioning BAV (n = 77, group 2); or ascending aorta replacement, with or without BAV repair, in the presence of ascending aorta dilation exceeding 45 mm, aortic root of less than 45 mm, and normally functioning or mildly insufficient BAV (n = 27, group 3).

RESULTS:

Compared with groups 2 and 3, group 1 patients were younger and affected by more severe BAV insufficiency and worse left ventricular function. In groups 1, 2, and 3, respectively, operative mortality was 2.1%, 1.3%, and 0%, and 5-year survival was 94% ± 4%, 92% ± 3.4%, and 100%. At 5 years, no patient in any group required reoperation on the ascending aorta or experienced aortic complications. In groups 2 and 3, root dimensions did not increase and were also significantly smaller compared with preoperative measurements (p < 0.05). Aortic regurgitation grade in group 3 (0.5 ± 0.8/4+) did not increase compared with the preoperative grade (0.8 ± 0.9/4+).

CONCLUSIONS:

At midterm follow-up, the Bentall operation remains associated with optimal results for the treatment of BAV, despite a worse preoperative presentation. In presence of a mildly diseased or normal aortic root and normal BAV function at the time of operation, less invasive surgical procedures, BAV-sparing, or repair procedures, appear to offer gratifying results.
