Abstract

Background

Paroxysmal atrial fibrillation (AF) and epicardial ventricular tachycardia (VT) are complex arrhythmias requiring precise, safe ablation. Zero-fluoroscopy radiofrequency ablation (RFA) minimizes radiation exposure while maintaining procedural accuracy.

FIH/Early Reports Summary

A 56-year-old male with diabetes, hypertrophic cardiomyopathy, AF, and VT underwent zero-fluoroscopy, single-stage RFA for both AF and epicardial VT. Integration of intracardiac echocardiography (ICE) and CARTO 3D mapping enabled effective ablation and restored sinus rhythm with symptom relief.

Discussion

This case highlights the utility of ICE and CARTO 3D in enhancing procedural precision and safety. Eliminating fluoroscopy reduces radiation risks, particularly in complex cases.

Novelty

This is the first report of single-stage, zero-fluoroscopy RFA for both AF and epicardial VT using ICE and 3D mapping.

阵发性心房颤动和心外膜室性心动过速的零透视射频消融

背景：阵发性心房颤动（AF）和心外膜室性心动过速（VT）是复杂的心律失常，需要精确、安全的消融。零透视射频消融（RFA）最大限度地减少辐射暴露，同时保持程序的准确性。FIH/早期报告总结：一名56岁男性糖尿病、肥厚性心肌病、房颤和室性心动过速患者接受了零透视、单期射频消融术治疗房颤和心外膜室性心动过速。心内超声心动图（ICE）和CARTO 3D制图的结合使消融有效，窦性心律恢复，症状缓解。本案例强调了ICE和CARTO 3D在提高手术精度和安全性方面的应用。取消透视检查可减少辐射风险，特别是在复杂病例中。这是首次使用ICE和3D定位技术对房颤和心外膜VT进行单期、无透视RFA的报道。
