ABSTRACT: Background
Index transcatheter aortic valve (TAV) expansion during TAV-in-TAV is crucial as it changes the valve-to-aorta distances and may increase the intraprocedural risk.Case summary
A TAV-in-TAV procedure was planned for a 90-year-old woman with prior TAV replacement (23-mm SAPIEN XT) who presented with prosthetic valve stenosis. Second TAV sizing was assessed by averaging the stent areas of the index TAV and by drawing a virtual circle on preprocedural computed tomography (CT). CT imaging also revealed significant calcification of the index TAV leaflets. The team opted for a one-size-smaller 20-mm SAPIEN3 valve. During the procedure, the index TAV expanded by creating a gap between the 2 valve stents. Postprocedural CT confirmed index TAV expansion and the calcified l
