Among women undergoing contemporary transcatheter aortic valve implantation (TAVI), the presence of atrial fibrillation (AF) as baseline was associated with significantly increased 12-month mortality, a recent study found. Patients from the Women’s International Transcatheter Aortic Valve Implantation (Win-TAVI) registry with available electrocardiogram (ECG) at baseline were compared according to the presence of AF. Researchers found:
- Of 993 women with available baseline ECG included in the study, 200 (20.1%) presented with AF.
- Patients with AF at baseline had higher Euroscore I score values and more frequently had chronic kidney disease or prior stroke; those without AF more frequently had coronary artery disease (CAD).
- In multivariate analysis, AF at baseline was associated with an increase of all-cause and cardiovascular death at 12 months.
- Patients with AF had longer length of hospital stay.
