“…Although commissural angles were not specifically measured in previous studies, intermediate type BAVs and unicuspid valves accounted for approximately one-fifth of that series, and these defects frequently display 3 equal-sized sinuses. 11 , 12 In our analysis at 7.5 years of maximal follow-up, aortic regurgitation remained low, and gradients acceptable. At the latest echocardiography follow-up, specific values for aortic regurgitation grade averaged 0.4 ± 0.8, and mean valve gradient 12.3 ± 5.9 mm Hg.…”
