OBJECTIVE: We evaluated the prevalence, trends, outcomes and the general experience of physicians performing atrial fibrillation ablation (AF-ABL) in the United States (US). BACKGROUND: AF-ABL is a non-pharmacological and potentially curative therapy for AF. Success rates for AF-ABL have been reported to be between 80 and 90%. Although there are numerous clinical trial addressing this therapy little is known about the general status of AF-ABL in clinical practice. METHODS: We administered a mailed survey to the physician members of a professional arrhythmia society (Heart Rhythm Society, formerly known as the North American Society of Pacing and Electrophysiology) who practiced in the US (n = 1843). RESULTS: There were 304 responses, 66% (n = 204) performed ABL and 30% (n = 92) performed AF-ABL. The study group performed a total of 5,592 AF-ABL from 2000 to 2003, out of 72,575 total ABL procedures during the same time period. There was a four-fold increase in the number of AF-ABL between 2000 and 2003 (2000: 628 vs. 2003: 2,575). In the same period, the self-reported short and long-term success rates of AF-ABL improved an average of 18 +/- 4% (p < or = 0.001). In 2003 the average self-reported one-month, one-year, and two-year success rates were: 71 +/- 4%, 66 +/- 5%, 63 +/- 6% respectively. The predicted five-year success was 60 +/- 4%. The average procedure took 4.5 +/- 0.4 hours. Physicians reported that approximately 29 +/- 4% of their patents were potential candidates for AF-ABL. CONCLUSIONS: AF-ABL is becoming a much more common procedure in the US. Over the last four years the perceived short and long term success rates of AF-ABL have improved. Success rates in this survey are 10 to 20% lower than those reported in the recent clinical trials.
