Paravalvular leak can complicate transcatheter aortic valve replacement with important prognostic implications. Correction of defects requires complex planning and execution. Multiple or irregular lesions, calcified annulus, and high sealing skirts on self-expandable devices are especially challenging. Such defects may be approximated using malleable vascular closure devices. ().
瓣周漏会使经导管主动脉瓣置换术复杂化，并具有重要的预后意义。纠正缺陷需要复杂的规划和执行。多个或不规则病变、钙化瓣环以及自膨胀装置上的高密封裙边尤其具有挑战性。此类缺陷可使用可塑形血管闭合装置进行修复。（）
