Abstract

Background

Posteroseptal accessory pathways (APs) associated with coronary sinus (CS) diverticulum present a rare and challenge for ablation. This study aimed to compare the safety and efficacy of conventional approach and three-dimensional (3D) mapping system in the catheter ablation.

Methods and Results

This was a retrospective study of all patients (from January 2013 to July 2022) who underwent catheter ablation of posteroseptal AP associated with CS diverticula in our center. Patients who underwent catheter ablation using the traditional fluoroscopy method were included in the conventional method group (n = 13). Patients who underwent catheter ablation using the 3D mapping method were included in the 3D mapping group (n = 11). Clinical characteristics, ablation procedure, and outcomes were recorded and analyzed between the two groups. Out of 669 patients with posteroseptal APs, 24 of them (3.6%) were associated with CS diverticula. All patients in both groups successfully completed the electrophysiological study. In the conventional method group, two patients experienced complications (one patient with pericardial effusion and the other patient with femoral arterial hematoma), and two patients had recurrence. However, no patients suffered from complications or recurrence during follow-up. The procedure time and fluoroscopy time in the conventional method group were significantly longer than those in the 3D mapping method group.

Conclusions

The utilization of 3D mapping led to reduced fluoroscopy time, shorter procedure duration, enhanced acute success rates, and decreased incidence of complications.

冠状窦憩室相关附属通路导管消融术中传统方法与三维绘图系统的比较：单中心经验。

背景：与冠状动脉窦（CS）憩室相关的室后附件通路（AP）是一种罕见的消融难题。本研究旨在比较传统方法和三维（3D）绘图系统在导管消融中的安全性和有效性：这是一项回顾性研究，研究对象为在本中心接受导管消融术的所有伴有CS憩室的后外侧AP患者（2013年1月至2022年7月）。使用传统透视法进行导管消融的患者被纳入传统方法组（n = 13）。使用三维映射法进行导管消融的患者被纳入三维映射组（n = 11）。记录并分析两组患者的临床特征、消融过程和结果。在669例后外侧AP患者中，有24例（3.6%）伴有CS憩室。两组患者均顺利完成了电生理检查。在传统方法组中，两名患者出现并发症（一名患者心包积液，另一名患者股动脉血肿），两名患者复发。但在随访期间，没有患者出现并发症或复发。传统方法组的手术时间和透视时间明显长于三维绘图法组：结论：三维绘图法缩短了透视时间，缩短了手术时间，提高了急性期成功率，降低了并发症的发生率。

期刊介绍： The ANNALS OF NONINVASIVE ELECTROCARDIOLOGY (A.N.E) is an online only journal that incorporates ongoing advances in the clinical application and technology of traditional and new ECG-based techniques in the diagnosis and treatment of cardiac patients. ANE is the first journal in an evolving subspecialty that incorporates ongoing advances in the clinical application and technology of traditional and new ECG-based techniques in the diagnosis and treatment of cardiac patients. The publication includes topics related to 12-lead, exercise and high-resolution electrocardiography, arrhythmias, ischemia, repolarization phenomena, heart rate variability, circadian rhythms, bioengineering technology, signal-averaged ECGs, T-wave alternans and automatic external defibrillation. ANE publishes peer-reviewed articles of interest to clinicians and researchers in the field of noninvasive electrocardiology. Original research, clinical studies, state-of-the-art reviews, case reports, technical notes, and letters to the editors will be published to meet future demands in this field.
