A virtual aortic annular plane that is built using the three hinge points, known as the hinge point-based annular plane (HPAP), is routinely used during transcatheter aortic valve replacement (TAVR). Abnormal aortic cusps (AAC) with unequal length and size influence the relationship of the HPAP to the aortic root axis significantly and pose challenges to valve deployment, leading to paravalvular leak and valve embolisation. Obtaining a centreline-based aortic annular plane in addition may help to understand valve deployment behaviour in AAC better.
在经导管主动脉瓣置换术(TAVR)中,通常使用基于三个铰链点的虚拟主动脉瓣环平面(HPAP)。瓣叶异常(AAC),包括瓣叶长度和大小不等,会显著影响 HPAP 与主动脉根部轴的关系,对瓣膜展开造成挑战,导致瓣周漏和瓣膜栓塞。获得基于中心线的主动脉瓣环平面可能有助于更好地理解 AAC 中的瓣膜展开行为。
