  Figure 1. Baseline and ablation characteristics and freedom from atrial arrhythmias. (A) Table 1 shows baseline characteristics of the cohort categorized by paroxysmal vs. non- paroxysmal AF. Patients with non-paroxysmal AF has higher BMI, more CHF, larger LA, lower LVEF and higher CHA2DS2-VASc score. Table 2 shows ablation characteristics including procedure time, number of PFA lesions, fluoroscopy time and lesion set performed. (B) and (C) Kaplan-Meier survival curve for freedom of atrial arrhythmias for the overall cohort and categorized by paroxysmal vs. non-paroxysmal AF. AF, atrial fibrillation; BMI, body mass index; CAD, coronary artery disease; CHA2DS2-VA, congestive heart failure, hypertension, age ≥75 years, diabetes mellitus, prior stroke or transient ischaemic attack, vascular disease, and age 65–74 years; CHA2DS2-VASc, congestive heart failure, hypertension, age ≥75 years, diabetes mellitus, prior stroke or transient ischaemic attack, vascular disease, age 65–74 years, and sex category; CHF, congestive heart failure; CKD, chronic kidney disease; COPD, chronic obstructive pulmonary disease; CTI, cavotricuspid isthmus; ESRD, end-stage renal disease; HLD, hyperlipidaemia; HTN,…
