Right atrial remodelling and prognosis in patients with severe atrial functional tricuspid regurgitation.

ABSTRACT:

Aims

Atrial functional tricuspid regurgitation (AFTR) is increasingly recognized as a distinct cause of tricuspid regurgitation, yet data on outcomes and their determinants are limited. This study examines the prognostic role of right atrial (RA) remodelling in patients with severe AFTR.

Methods and results

This retrospective study included consecutive patients with severe AFTR. The primary outcome was all-cause mortality. Cutoff values for RA and right ventricular (RV) sizes related to mortality were identified using receiver operating characteristic curves and maximally selected rank statistics. The cohort included 155 patients with severe AFTR, 96.1% of whom had atrial fibrillation. Of these, 121 received medical treatment, and 34 underwent surgery during follow-up. In th
