右房峡部已被证实为典型心房扑动的关键传导部位,全程线性透壁消融右房峡部是临床介入治疗典型房扑的首选策略;但右房峡部内成分构成复杂,其解剖特点是影响消融结果与预后的重要因素。近年来,随着多维超声、高分辨率计算机体层成像和磁共振在心脏成像的广泛应用和大量相关临床研究的开展,右房峡部长度增加、存在欧氏嵴以及过深的隐窝和囊袋、与下腔静脉成角增加等解剖变异均可能增加导管消融的难度,对个体而言,舒张状态下的右房峡部长度是影响消融成功率的重要因素。现就此研究进展作出综述。
Right atrium isthmus has been confirmed as a typical atrial flutter of the key conduction site, the entire linear transmural ablation of the right atrium is the preferred strategy for clinical interventional treatment of atrial flutter; but the composition of the right atrium isthmus complex composition, the anatomical feature is the impact of ablation Results and prognosis of the important factors. In recent years, with the multi-dimensional ultrasound, high-resolution computer tomography and magnetic resonance imaging in a wide range of heart and the development of a large number of related clinical studies, the right atrial isthmus increases in length, the presence of Euclidean crest and deep crypt and sac Bag, and angulation of the inferior vena cava may cause an increase in the difficulty of catheter ablation. For individuals, the length of the right atrium isoforrhea is an important factor affecting the success rate of ablation. Now on the progress of this review.
