Zusammenfassung: | Long-Term Follow-Up After Cryothermic Ostial Pulmonary Vein Isolation in Paroxysmal Atrial Fibrillation Wendel Moreira, Randy Manusama, Carl Timmermans, Benoit Ghaye, Suzanne Philippens, Hein J. J. Wellens, Luz-Maria Rodriguez In patients presenting with early paroxysmal atrial fibrillation (PAF), a more localized ablation strategy (targeting triggers) might be enough to provide a successful outcome. Using cryothermy in PAF patients undergoing segmental pulmonary vein (PV) isolation, we were able to show that 49% achieved complete success (no atrial fibrillation [AF] and no antiarrhythmic drugs [AADs]), 22% were AF free with AADs and 11% reported >50% improvement with AADs (still having sporadic bursts of AF) during a mean follow-up of 33 ± 15 months. Overall, 82% of the patients benefited from the procedure. Also, if the arrhythmogenic PV was identified and isolated, no recurrences were observed, indicating no need to isolate all PV. |
