Study Arms:
- CABG, AVR or CABG+AVR and PVI (Type: EXPERIMENTAL): Coronary artery bypass (CABG), aortic valve replacement for aortic stenosis (AVR) or combination (CABG+AVR) using cardio-pulmonary bypass (CBP) and occlusion. Concomitant pulmonary vein isolation (PVI) in CBP prior to occlusion and CABG
- CABG, AVR or CABG+AVR (Type: ACTIVE_COMPARATOR): Coronary artery bypass (CABG), aortic valve replacement for aortic stenosis(AVR) or combination(CABG+AVR) using cardio-pulmonary bypass (CBP) and occlusion. No operative procedures for the treatment of atrial fibrillation

Based on this trial design, predict the completion outcome and termination type (if applicable).
