A 74-year-old male patient was scheduled to undergo transcatheter aortic valve replacement (TAVR) due to symptomatic severe aortic stenosis. Ultrasound measurement of aortic orifice area was 0.88 cm2. Preoperative computed tomography (CT) evaluation revealed a tricuspid aortic valve (AV). The right and noncoronary sinuses exhibited heavy calcification, with a total calcification score of 1018 mm3 (Fig. 1A). The height of the left coronary opening measured 10.6 mm, the perimeter-derived annular diameter was 26.7 mm, and the mean sinus diameter was 32.1 mm. The procedure was planned to involve the implantation of a 26-mm Taurus (Peijia Medical Technology, Suzhou, China) self-expanding valve.
