Catheter ablation increases life expectancy in subsets of patients with atrial fibrillation (AF) by reducing risk of stroke and heart failure. Various methods are being used worldwide with comparable success rate of restoring sinus rhythm. A risk of short-term sudden mortality after pulsed field ablations has been questioned recently.

To analyze long-term survival after AF ablation using radiofrequency, cryo, and pulsed field energy and to investigate potential risk of sudden death after ablations.

We analyzed the follow-up of total 8175 patients (63% men, age 66±11 years, BMI 30±6) after catheter ablation for paroxysmal (53%) or persistent AF between years 2017 and 2025. Three ablation catheters with different forms of ablation energy were used: Navistar SmartTouch, CryoCath Arctic Front Advance catheter, and FaraWave. Mortality data were extracted from national healthcare registry and combined with clinical follow-up. Overall mortality was 1.75% per year and did not differ between groups when adjusted to age. Cox analysis and log-rank test identified significant mortality variables as age >80 years (HR 1.04, CI 1.04-1.05), male sex (HR 1.27, CI 1.1-1.5), and persistent type of AF (HR 2.3, CI 2.0-2.7). On the contrary, the mortality was not affected by obesity and there was no unforeseen or short-term mortality observed in any of the three energy forms.

This large single-center cohort with 8 years of follow-up excluded differences in survival between radiofrequency, cryo, and pulsed field energy AF ablation. No early sudden mortality after catheter ablations was observed.
