Minimally Invasive Bicuspid Aortic Valve Repair using Geometric Ring Annuloplasty

Publication date: Available online 21 June 2019Source: The Annals of Thoracic SurgeryAuthor(s): Vinay Badhwar, Takashi Murashita, Lawrence M. Wei, J. Scott RankinAbstractA 51-year-old male with congestive heart failure, Sievers Type 1 BAV, and severe aortic insufficiency had an upper mini-sternotomy. The annulus sized to 27 mm, and the non-fused cusp to a 21-mm bicuspid ring. Using the geometric annuloplasty ring, two 180° subcommissural ring posts, 3 non-fused looping annular sutures, and 4 fused annular sutures were placed. Plication sutures raised non-coronary leaflet to a reference effective height of 10 mm, and fused leaflet cleft was closed linearly to the same effective height and length. Post-repair echo showed good leaflet mobility, no residual leak, and a mean valve gradient of 10 mmHg.
