Knowledge of the coronary sinus (CS) anatomy is crucial for implantation of cardiac resynchronization therapy (CRT). Obstacles to CS entry, such as the Eustachian ridge and Thebesian valve, as well as within the CS, such as Vieussen's valve and the vein of Marshall, are important to understand and differentiate during implantation or to identify earlier by imaging. Anatomic knowledge is mandatory to select the most suitable side branch for lead implantation. Modern tools and techniques almost always enable other anatomic problems, such as tortuous, small, short, or overly straight side branches, to also be overcome.
了解冠状窦(CS)解剖结构对于心脏再同步治疗(CRT)的植入至关重要。在植入过程中,需要了解和区分 CS 内的障碍物,如耳咽管嵴和 Thebesian 瓣,以及 CS 内的障碍物,如 Vieussen 瓣和 Marshall 静脉,以便在植入时进入 CS 或通过影像学更早地识别。解剖学知识对于选择最适合的侧支进行导线植入至关重要。现代工具和技术几乎总是能够克服其他解剖问题,如扭曲、细小、短或过于直的侧支。
