[Technical standards for performing radiofrequency catheter ablation for atrial fibrillation: a series of consortium standards].

Atrial fibrillation (AF) has emerged as a major global cardiovascular disease in the 21st century. In China, there are greater than 12 million patients with AF, and its incidence continues to rise. AF affects patients' quality of life and significantly increases the risks of mortality, stroke, heart failure, cognitive impairment, and dementia. In recent years, multiple clinical guidelines have expanded the indications for catheter ablation and raised its level of recommendation. Concurrently, there has been a rapid and sustained increase in the number of AF ablation procedures performed across China. Among these, radiofrequency catheter ablation remains the most used method. Consequently, the Chinese Heart Rhythm Society of the Chinese Society of Biomedical Engineering, in collaboration with 40 arrhythmia centers and 60 leading clinical experts specializing in AF catheter ablation, developed a comprehensive set of standards. These standards were developed based on extensive clinical experience accumulated in recent years and the latest national and international AF guidelines and consensus documents. They address five critical domains: periprocedural management, intra-atrial septal puncture, anatomical reconstruction and electroanatomic mapping, ablation, and complication identification and management. By providing a structured framework, these standards aim to guide AF catheter ablation practice, thereby enhancing procedural safety and efficacy.
