Why the study?
Does the incidence of new-onset atrial fibrillation differ between TAVI and AVR in patients undergoing aortic valve replacement?
Does the incidence of new-onset atrial fibrillation differ between TAVI and AVR in patients undergoing aortic valve replacement?
New-onset atrial fibrillation is a significant complication following aortic valve replacement, occurring more frequently after surgical AVR compared to TAVI.
Suggests TAVI may lower new-onset AF risk versus AVR; observational data leave open confounding and require RCT confirmation.
In this large nationwide study, a substantial burden of new-onset atrial fibrillation was observed after TAVI and AVR. The incidence of new-onset atrial fibrillation was higher after AVR than after TAVI in a patient-level state inpatient database.
