Efficiency, Safety, and Efficacy of High-Power Short-Duration Radiofrequency Ablation in Patients with Atrial Fibrillation

Abstract: Pulmonary vein isolation (PVI) is the cornerstone therapy of atrial fibrillation (AF). Radiofrequency catheter ablation (RFCA) is performed using a point-by-point method to achieve durable PVI. However, this procedure remains complex and time-consuming, and the long-term clinical outcomes are still not satisfactory. Recently, there has been increasing interest in the clinical application of high-power short-duration (HPSD) approaches in the field of RFCA. HPSD ablation, distinguishing it from the conventional … Show more

“…FPI was achieved in 35.0% in the “5–6 mm” group and 90.9% in the “3–4 mm” group ( p < 0.0001) ( 19 ). In our present study, we used ILD < 6 mm both in LPLD and HPSD (50 W) groups, and according to our findings, HPSD ablation improves the chance of creating a contiguous lesion set, probably due to wider RF ablation lesions, which seem to increase the FPI rate by boosting the continuity of the circumferential lesions ( 33 ). Of note, lesion size might be smaller in case of vHPSD ( 34 ).…”

“…While conventional settings during RF ablation involve applying low power for long times, a new setting based on high power and short duration has recently been suggested as safer and more effective 33–36 . Overall, high‐power short‐duration lesions were significantly wider, and of slightly lower or similar depth compared to standard settings 33 .…”

“…Although HPSD ablation is increasing in epidemic management strategies for patients with AF, the narrow efficacy and safety window of HPSD ablation should be recognized. 9 LSI is calculated by integrating the power, CF, impedance, and time, which can accurately predict lesion dimensions in an experimental study and is commonly used as a real-time surrogate to guide RF duration and predict lesion size. 11,14,15 Compared with LP ablation, HP ablation requires a shorter RF duration to achieve a prespecified LSI.…”

“…2,3 Although a series of clinical studies have revealed that HPSD ablation is feasible and effective for achieving a high rate of first-pass PVI and reducing procedure complications, [4][5][6][7][8] the longterm efficacy of this strategy remains undefined. 9 Moreover, a novel proprietary index, the lesion size index (LSI), incorporating power, contact force (CF), impedance, and time, has been used as a real-time surrogate to guide RF duration and has been found to be highly predictive of RF lesion dimension, and lower LSI values are associated with a higher risk of AF recurrence. [10][11][12][13] Although recently published data have revealed that LSI-guided HP ablation for PVI could help manage RF duration and improve durable and transmural lesions, 14,15 the long-term impact of LSI-guided HP ablation for PVI in patients is still unclear.…”
