The purpose of this study was to determine the effect of simultaneous coronary artery bypass grafting (CABG) and the influence of valve structure on both early and late survival in sexagenarians having aortic valve replacement (AVR) for aortic stenosis (AS) (with or without aortic regurgitation). We analyzed survival and valve structure in 289 sexagenarians having AVR for AS from 1993 through 2005 at Baylor University Medical Center, including 147 (51%) with and 142 (49%) without simultaneous CABG. Of the 282 patients with information available, 13 (4.6%) died within 30 days of operation and 1 additional patient, from 31 to 60 days after operation (5.0% 60-day mortality). Sixty-day mortality was similar (6% and 4%) in the groups with and without simultaneous CABG. A total of 66 patients (23%) died from >60 days up to 13 years postoperatively. The unadjusted survival analysis showed that late survival was not affected by gender (male versus female), aortic valve structure (unicuspid, bicuspid, and quadricuspid versus tricuspid) or preoperative severity of the AS (transvalvular peak pressure gradient >50 mm Hg versus < or =50 mm Hg), or by performance of CABG. The aortic valve was congenitally unicuspid in 10 patients (3%), congenitally bicuspid in 170 (59%), 3-cuspid in 107 (37%), congenitally quadricuspid in 1 patient, and the valve structure was indeterminate in 1 patient. In conclusion, gender, valve structure, preoperative severity of the AS, or performance of simultaneous CABG did not effect unadjusted survival in sexagenarians undergoing AVR for AS.
