Better Outcomes in High-Power Short-Duration Compared to Low-Power Long-Duration Atrial Fibrillation Ablation in One-Year Follow-Up: OAJBS Publishers

Better Outcomes in High-Power Short-Duration Compared to Low-Power Long-Duration Atrial Fibrillation Ablation in One-Year Follow-Up by Fabricio Vassallo in Open Access Journal of Biomedical Science

Introduction: Different results are described after atrial fibrillation ablation and multiples predictors of recurrence are well established. Objective: Evaluate and analyze if patients submitted to first time atrial fibrillation (AF) ablation with high-power short-duration (HPSD) have better outcomes compared to low-power long-duration (LPLD). Methods: Observational, retrospective study, 144 patients submitted to HPSD and LPLD ablation. HPSD: 71 patients, 50(70.42%) males, mean age 59.73 years, 52(73.24%) hypertension, 44(61.97%) obstructive apnea, 23(32.39%) arterial disease, 20(28.17%) Diabetes, and 10(14.08%) strokes. CHADS2VASC2 2.57. CT: 73 patients, 50(68.49%) males, mean age 60.7 years, 53(72.60%) hypertension, 41(56.16%) obstructive apnea, 28(38.36%) arterial disease, 14(19.17%) Diabetes and 8 (10.96%) strokes. CHAD2SVASC2 2.22. Results: Recurrence occurred in 33 patients (22.92%) at 12 months follow-up, of these, HPSD with 9 patients and LPLD with 24 patients. At the end of study 62 (87.32%) of 71 HPSD patients were in sinus rhythm comparing to 49 (67.12%) of 73 patients in LPLD (P of .0039). Conclusion: HPSD compared to LPLD showed a superiority in maintaining sinus rhythm at 12 months and a significant lower recurrence rate. Also, lower procedure time, esophageal heating and radiofrequency time was significant lower in HPSD technique.
