Repair of the Common Type of Bicuspid Aortic Valve with Insufficiency

Monday, July 8, 2013

Presented at the STS 2011 Annual Meeting

Surgical techniques for repair of insufficient bicuspid aortic valves are now quite reproducible. Outcome analyses have shown low late valve-related complication and failure rates. This video illustrates bicuspid repair techniques emphasizing inter-patient variability and operative decision-making.

Videos and operative echocardiograms from 4 patients are shown to illustrate the anatomic spectrum of bicuspid valves with fusion of left/right coronary cusps. Anatomic variability is categorized into 3 areas: 1) annular size, 2) degree and type of leaflet prolapse, and 3) magnitude of fused cusp clefting. The defects are corrected by varying degrees of 1) commissural annuloplasty, 2) leaflet plication to correct prolapse, and 3) cleft closure.

Each of the 4 patients had variable application of repair techniques, depending on the individual anatomy. All obtained excellent anatomic and hemodynamic results, with negligible residual leak, good leaflet effective height (> 8 mm), and adequate leaflet coaptation area. Individual decision-making is discussed.

We conclude that common type of bicuspid aortic valve with insufficiency can be repaired reproducibly with good anatomic and clinical results. Repair techniques should be individualized to each patient’s anatomy. Surgical reconstruction now might be considered the primary procedure for this disorder.
