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

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

“…In contrast, the BAV ring achieves symmetrical 180° fused and nonfused annular segments in all cases, no matter the baseline anatomy. 2 , 22 In this way, problems associated with 3 equal sinuses in IBAV are overcome routinely, making simple 2-leaflet repairs highly reproducible. Finally, unicuspid valves frequently have 3 equal sinuses, and bicuspid ring annuloplasty also facilitates autologous reconstruction of unicuspid defects, without the need for pericardial augmentation.…”
