Transcatheter Aortic Valve Replacement for Bicuspid Aortic Valve: Challenges and Pitfalls
1Interventional Cardiology, Cedars-Sinai Heart Institute, 8700 Beverly Boulevard, Los Angeles, CA 90048, USA.
Abstract:
Because of the unfavorable anatomic features of bicuspid aortic stenosis (AS), the outcomes of transcatheter aortic valve replacement (TAVR) in bicuspid AS were suboptimal, particularly when using the first-generation transcatheter valves. However, the newer-generation transcatheter valves significantly improved the outcomes of TAVR in bicuspid AS. Nonetheless, long-term durability of transcatheter valves and concomitant aortopathy should be taken into account. Considering the expanding indication of TAVR to lower the surgical risk and a younger population, these issues should be evaluated in future studies.

Heart Valves
The AV valves prevent the backflow of blood from the ventricles to the atria during ventricular contraction. These valves function with the assistance of the chordae tendineae and papillary muscles. When the ventricles are relaxed, the chordae tendineae are slack, allowing blood to flow from the atria into the...
