Evolution of techniques for repair of intermediate-type bicuspid aortic valves

Autologous repair of “very asymmetric” bicuspid aortic valves using geometric ring annuloplasty

“…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.…”

Use of aortic wall patches as leaflet replacement material during aortic valve repair

“…He underwent a bi-atrial maze procedure and AVr. The aortic valve was an intermediate-type BAV, 16 with a small left cusp. The noncoronary cusp sized to a 23-mm bicuspid annuloplasty ring, and the annulus was 27 mm.…”
