Trans-catheter mitral valve replacement (TMVR) procedures had emerged as an alternative solution for patients who are at high risk for mitral valve surgery. Although cardiac computed tomography (CT) remains the standard method for procedural planning, there is no full agreement on the best systolic phase for quantitation of the neoLVOT. Furthermore, a new three-dimensional trans-esophageal echocardiography (3DTEE) based software was developed to serve as filter and or an alternative for patients who cannot have CT due to any contraindication.

经导管二尖瓣置换术前使用三维经食管超声心动图进行 neoLVOT 评估的标准化和验证

经导管二尖瓣置换术 (TMVR) 手术已成为二尖瓣手术高风险患者的替代解决方案。尽管心脏计算机断层扫描 (CT) 仍然是程序规划的标准方法，但对于 neoLVOT 定量的最佳收缩期尚未达成完全一致。此外，还开发了一种新的基于三维经食管超声心动图 (3DTEE) 的软件，作为因任何禁忌症而无法进行 CT 检查的患者的过滤器和/或替代方案。
