Background:
Functional tricuspid regurgitation (TR) develops in atrial fibrillation (AF), but its natural history after transcatheter aortic valve replacement (TAVR) remains unclear.
Methods And Results:
Of 981 patients from a single-center registry, AF/atrial flutter (AFL) was present in 169. Over 5 years, severe TR developed in 11.7% with AF/AFL vs. 0.8% without. AF/AFL independently predicted TR progression (sub-distribution hazard ratio 1.82, 95% confidence interval: 1.34-2.47).
Conclusions:
AF/AFL significantly increases TR progression risk post-TAVR, highlighting the importance of surveillance and preventive strategies.
