Transaortic septal myectomy is a procedure that involves a learning curve for surgeons because the bulging interventricular septum usually interferes with the visualization of the deep parts of the left ventricular chamber. In this case report, we demonstrate computed tomography virtual endoscopy for preoperative simulation, which enabled us to clearly image the relationship among the bulging septum, the expected myectomy area, and the structures deep in the left ventricle, such as the papillary muscle and abnormal muscular bundles, which are hidden by the hypertrophic septum, thus preventing visualization. This approach could make minimally invasive transaortic septal myectomy safe and easy.
经主动脉间隔心肌切除术是一种外科医生需要经历学习曲线的手术，因为肥厚的室间隔通常会干扰左心室深部结构的可视化。在本病例报告中，我们展示了计算机断层扫描虚拟内镜用于术前模拟，这使我们能够清晰地成像肥厚间隔、预期的心肌切除区域以及左心室深部结构（如乳头肌和异常肌束）之间的关系，这些结构被肥厚的间隔遮挡，从而无法可视化。这种方法可以使微创经主动脉间隔心肌切除术变得安全且容易。
