Transcatheter aortic valve replacement (TAVR) for patients with a bicuspid aortic valve (BAV) is challenging as the extent and location of valve calcification as well as bulky leaflets and an enlarged root may increase the risk of transcatheter heart valve (THV) displacement, distortion, or malfunctioning. We report successful TAVR for an 84-year-old man with a BAV. The THV was implanted closer to the aorta than usual to avoid spreading of the bulky leaflets over the THV outflow. Following implantation, there was trivial paravalvular leakage, with no distortion or malfunction detected.
对于患有二叶式主动脉瓣（BAV）的患者，经导管主动脉瓣置换术（TAVR）具有挑战性，因为瓣膜钙化的程度和位置以及增厚的瓣叶和扩大的根部可能会增加经导管心脏瓣膜（THV）移位、变形或功能障碍的风险。我们报告了一例成功为一名84岁患有BAV的男性实施TAVR的病例。THV的植入位置比通常更靠近主动脉，以避免增厚的瓣叶在THV流出道扩散。植入后，瓣周漏轻微，未检测到变形或功能障碍。
