| Abstract: | This case report is about an 85‐year‐old woman with bicuspid aortic stenosis (AS). Although preoperative multimodality imaging showed challenging anatomical aspects, transcatheter aortic valve replacement (TAVR) was selected to be performed as a less invasive alternative treatment approach, owing to her comorbidity. Postoperative transesophageal echocardiography and multidetector‐row computed tomography revealed the presence of “locked‐in leaflet” caused by stent distortion due to pinching by calcified native leaflets, with nodular calcification preventing the full expansion of the valve, which resulted in moderate perivalvular leakage. This is the first reported case of bicuspid AS treated with TAVR that eventually resulted in “locked‐in leaflet.” |
