Discussion
This 3-center retrospective registry demonstrated 3 main findings: 1)
implantation depth - MS length and severe LVOT calcification were
independent predictors of new CD in BAV; 2) when comparing matched BAV
and TAV group, MS length was not different, but the incidence of new CD
was higher in the patients with BAV, 3) BAV anatomy resulted in a deeper
valve implantation, which may explain the increased incidence of CD
