Aortic Dissection After Previous Aortic Valve Replacement for Bicuspid Aortic Valve Disease

The effect of bicuspid aortic valve (BAV) phenotype on the future risk of type A aortic dissection is unknown. On the basis of previous data [(1)][1], we hypothesized that the risk of post–aortic valve replacement (AVR) aortic dissection might be different in BAV insufficiency versus BAV stenosis
