Key result
Moderate tricuspid regurgitation, present in 7% of the study population, was associated with a sicker clinical profile including higher rates of atrial fibrillation and heart failure.
Why the study?
Does unaddressed preoperative moderate tricuspid regurgitation affect long-term survival in patients undergoing mitral valve repair for severe degenerative mitral regurgitation?
Does unaddressed preoperative moderate tricuspid regurgitation affect long-term survival in patients undergoing mitral valve repair for severe degenerative mitral regurgitation?
Moderate tricuspid regurgitation in patients undergoing mitral valve repair marks a sicker patient population and should not be ignored given its potential impact on outcomes.
Long has been the debate on when to repair the tricuspid valve (TVr) during mitral surgery. Hage and colleagues1 retrospectively reviewed 5467 patients with severe degenerative mitral regurgitation undergoing mitral valve repair (MVr) without concomitant TVr, to evaluate the correlation of unaddressed preoperative moderate tricuspid regurgitation (TR) on long-term survival. Patients with moderate TR, which represented 7% of the study population, were sicker than those with mild or trace TR, exhibiting higher rates of preoperative atrial fibrillation, congestive heart failure, advanced age, larger left atrial diameters, and higher right ventricular systolic pressures.

Kazaleh et al. (2025) conducted an editorial in Severe degenerative mitral regurgitation (n=5,467). Preoperative moderate tricuspid regurgitation vs. Mild or trace tricuspid regurgitation was evaluated on Long-term survival. Moderate tricuspid regurgitation, present in 7% of the study population, was associated with a sicker clinical profile including higher rates of atrial fibrillation and heart failure.
