AF: Atrial fibrillation; ASD: atrial septal defect; LV EF: Left ventricular ejection fraction; NA: Not applicable; pRBBB: Partial right bundle branch block; RA: Right atrium; RBBB: Right bundle branch block; RV: Right ventricle; TAPSE: Tricuspid annular plane systolic excursion; TI: Tricuspid valve insufficiency; TIA: Transient ischemic attack; VF: Ventricular fibrillation; VT: Ventricular tachycardia.
Values are presented as mean (SD) for continuous variables or percentage (number of patients) for categorical variables.
