Background To evaluate myocardial injury in Atrial Fibrillation (AF) patients undergoing High Power Short Duration radiofrequency (HPSD) and visually guided Laser Balloon Ablation (LBA). Methods and results In this single center registry we prospectively enrolled 40 patients (67% male), mean age 63±9, with paroxysmal or persistent AF (see table I). The ablation target has been the pulmonary vein isolation (PVI) with LBA and wide area circumferential ablation (WACA) with HPSD. 6 and 18 hours post-procedure samples of high sensitive cardiac troponin I (cTnI) were collected. The results show not significant differences in target population and no significant differences in high sensitive cardiac troponin I (cTnI pg/ml) levels at 6h (HPSD cTnI =806±496 pg/ml vs laser cTnI = 664±339 pg/ml p=0.17) and 18 hours after ablation (HPSD cTnI =833±540 pg/ml vs laser cTnI = 1081±962 pg/ml p=0.07). Conclusion These results indicate that myocardial injury induced by HPSD and LBA at 6 and 18 hours after procedure are similar targeting WACA and PVI respectively. This registry is ongoing to evaluate freedom from AF at 12 months follow up. |
