TAVR protocol computed tomography (CT) scans demonstrated no significant aortic annular calcification; however, the presence of a calcified nodule could be seen in the annulus shown in Figure 1 (left panel), which extende...
手术前,根据制造商的数据确定失败生物瓣膜的内径。这代表了经导管装置尺寸的关键参数。术中通过经食道超声心动图对内径进行额外评估,并在CT扫描前进行测量。最佳经导管心脏瓣膜的尺寸选择基于制造商的建议,并得到“ViV主动脉”应用程序的支持...
