The superiority of high‐power short‐duration radiofrequency catheter ablation strategy for atrial fibrillation treatment: A systematic review and meta‐analysis study

“…In this step, we excluded 12 studies because of: (i) substudy of the included studies (n = 2), (ii) AI guided catheter ablation (n = 2), (iii) outcomes of interest were not reported (n = 3), and (iv) incomparable treatment and control. In the end, we had 13 studies to be included in qualitative and quantitative data synthesis 25‐37 . Figure 1 represents the study selection process.…”

“…In minimizing the risk of bias, we only included high‐quality studies. We had 2 RCTs and 11 cohort studies in this systematic review and meta‐analysis study 25‐37 . Most of them were single‐center studies 25‐31,34‐37 .…”

“…We had 2 RCTs and 11 cohort studies in this systematic review and meta‐analysis study 25‐37 . Most of them were single‐center studies 25‐31,34‐37 . Four studies only included paroxysmal AF patients, while 9 studies include paroxysmal AF and nonparoxysmal AF patients 25‐27,30,31,33,34,36,37 .…”

“…Most of them were single‐center studies 25‐31,34‐37 . Four studies only included paroxysmal AF patients, while 9 studies include paroxysmal AF and nonparoxysmal AF patients 25‐27,30,31,33,34,36,37 . Only two studies used PVI only ablation, 29,32 whereas other studies used the combination of linear ablation, box isolation, superior vena cava isolation, cavotricuspid isthmus ablation, and/or another non‐pulmonary vein (non‐PV) foci ablation in addition to PVI 25‐28,30,31,33‐37 .…”

The follow‐up period duration of the study from Castrejón‐Castrejón et al was 3 days because they assessed the safety and feasibility of the HPSD ablation strategy 27 .…”
