With the aging population, significant valvular heart disease is increasingly identified in patients too frail to undergo surgery. Transcatheter therapies for structural heart disease represent an alternative therapeutic approach for these patients. During these procedures, direct visualization of the surgical field is replaced by image guidance for intraprocedural decision making. Advances in percutaneous devices and delivery systems, coupled with enhancements in 3-dimensional imaging with multiplanar reformatting, have allowed these procedures to be performed safely and with excellent results. This article describes the role of cross-sectional imaging for detailed assessment and preprocedural planning of aortic, mitral, and pulmonic valve interventions.
随着人口老龄化,越来越多体弱不能接受手术的患者被发现患有严重的瓣膜性心脏病。结构性心脏病的经导管治疗为这些患者提供了一种替代的治疗方法。在这些手术中,手术区域的直接可视化被图像引导替代,以用于术中决策。经皮器械和输送系统的进步,以及多平面重建的三维成像增强,使这些手术能够安全地进行,并取得了极好的效果。本文描述了横断面成像在主动脉瓣、二尖瓣和肺动脉瓣介入治疗的详细评估和术前规划中的作用。
