Objective: This study aimed to report the efficacy and safety of 1-year outcome for single-procedure radiofrequency catheter ablation (RFCA) at Phramongkutklao Hospital.
Methods: Review of medical records was carried out on consecutive patients with symptomatic atrial fibrillation (AF) who had undergone first-time RFCA in Phramongkutklao Hospital between January 2009 and December 2018. The efficacy and safety of outcomes after 1 year of RFCA were collected, analyzed, and validated using descriptive data.
Results: 61 patients underwent RFCA for the first time. 77.05% were male, with a mean age of 58.31 ± 10.83 years. Paroxysmal AF presented in 65.57%. 49.18% had hypertension, 9.84% had a history of ischemic stroke or transient ischemic attack, 6.56% had diabetes, 6.56% had coronary artery disease, and 4.92% had heart failure. 96.72% of RFCA procedures were performed under local anesthesia and conscious sedation. Pulmonary vein isolation was performed in all patients. Roofline, mitral isthmus line, and posterior wall isolation were created in 27.87%, 13.11%, and 3.28%, respectively. Additional complex fractionated atrial electrograms (CFAEs) were targeted in 19.67%. After 12 months, 45.45% remained in sinus rhythm, with only one patient experiencing a procedure-related complication with cardiac tamponade.
Conclusion: The 1-year results of single-procedure RFCA for treating AF at our center, while not highly successful in our first decade, were comparable to other series. Notably, there was a relatively low rate of complications.
