Tricuspid regurgitation in acute heart failure: is there any incremental risk?

Aim: Significant tricuspid regurgitation (TR) is common in heart failure (HF) and portends poor prognosis. We sought to determine whether the poor outcome results from the TR itself, or whether the TR is a surrogate marker of advanced left-sided myocardial or valvular heart disease.

Methods And Results: We studied 639 patients admitted for acute HF.
