Pulsed field ablation and cryoballoon ablation for pulmonary vein isolation: insights on efficacy, safety and cardiac function.
Background: Pulmonary vein isolation (PVI) has become the cornerstone treatment of atrial fibrillation (AF). While in cryoablation cell damage is caused by thermal effects, lately, pulsed field ablation (PFA) has been established as a novel non-thermal tissue-specific ablation modality for PVI. However, data comparing outcomes of patients undergoing either PFA or cryoballoon ablation (CBA) for primary PVI are sparse.
Methods: Consecutive patients with AF undergoing PVI by either CBA or PFA were included in the analysis. The primary outcome was the time to AF/AT recurrence. For secondary outcomes, clinical and periprocedural parameters were compared.
Results: In total, outcomes of 141 AF patients treated by PFA (94 patients) or CBA (47 patients) were compared. After 365 days, 70% of patients in the PFA group and 61% of patients in the CBA group were free from AF/AT (HR 1.35, 95% CI 0.60-3.00; p = 0.470). No deaths occurred. While symptoms alleviated in both groups, only after PFA, we observed significant improvement of left atrial volume index (PFA group baseline: 40 [31;62] ml/m2, PFA group follow-up: 35 [29;49] ml/m2; p = 0.015), NT-pro BNP levels (PFA group baseline: 1106 ± 2479 pg/ml, PFA group follow-up: 1033 ± 1742 pg/ml; p = 0.048), and left ventricular ejection fraction (LVEF) (PFA group baseline: 55 [48;60] %, PFA group follow-up: 58 [54;63] %; p = 0.006). PVI by PFA was the only independent predictor of LVEF improvement.
Conclusion: In our study, we show that CBA and PFA for PVI are of similar efficacy when it comes to AF recurrence. However, our findings suggest that PFA rather than CBA might induce left atrial reverse remodeling thereby contributing to left ventricular systolic function.
期刊介绍:
The Journal of Interventional Cardiac Electrophysiology is an international publication devoted to fostering research in and development of interventional techniques and therapies for the management of cardiac arrhythmias. It is designed primarily to present original research studies and scholarly scientific reviews of basic and applied science and clinical research in this field. The Journal will adopt a multidisciplinary approach to link physical, experimental, and clinical sciences as applied to the development of and practice in interventional electrophysiology. The Journal will examine techniques ranging from molecular, chemical and pharmacologic therapies to device and ablation technology. Accordingly, original research in clinical, epidemiologic and basic science arenas will be considered for publication. Applied engineering or physical science studies pertaining to interventional electrophysiology will be encouraged. The Journal is committed to providing comprehensive and detailed treatment of major interventional therapies and innovative techniques in a structured and clinically relevant manner. It is directed at clinical practitioners and investigators in the rapidly growing field of interventional electrophysiology. The editorial staff and board reflect this bias and include noted international experts in this area with a wealth of expertise in basic and clinical investigation. Peer review of all submissions, conflict of interest guidelines and periodic editorial board review of all Journal policies have been established.
