Fatal outcome after self-expanding transcatheter aortic valve replacement of the bicuspid valve due to infolding: a case report

This case highlights the importance of comprehensive preoperative anatomical assessment and intraoperative decision making in high-risk patients, particularly those with bicuspid valves. Valve selection (considering the valve type and size) must be meticulously tailored to the anatomical features surrounding the annulus. In addition, upon its recognition, substantial infolding should be promptly addressed by recapturing the valve, adjusting the valve size, or redeploying the valve with additional balloon aortic valvuloplasty.
