Long-term Outcomes of Isolated Tricuspid Valve Surgery According to Preoperative Clinical and Functional Staging

Completed

• Conditions: Tricuspid Regurgitation

• Registration Number: NCT05721417
• Lead Sponsor: Michele De Bonis

Brief Summary

Tricuspid regurgitation (TR) was identified as an independent prognostic factor associated with excess mortality and morbidity, independent of left ventricular (LV) function and pulmonary hypertension. Isolated tricuspid surgery has been performed for a long time in a few selected cases, however in recent years several studies have underlined how the poor outcomes described for isolated tricuspid valve surgery seem to be related to the baseline characteristics of the patients and to late referral for surgical treatment rather than the intervention itself. To facilitate patient screening, a new clinical and functional TR staging system has recently been proposed. This classification, which evaluates the progression of morphological variations of the tricuspid valve and right ventricle (RV) in association with the onset of symptoms, identifies several parameters and factors that can be useful for a better stratification of surgical risk. Rather than simply assessing the degree of TR, this new staging mechanism also focuses on symptoms, RV remodeling and function, medical therapy, and right heart failure hospitalizations.

Investigators previously focused on the short-term (mainly hospital) outcomes of patients undergoing isolated surgery for severe TR, who were classified at baseline according to this clinical and functional staging system. Results showed that a more comprehensive classification reflects the population and hospital outcomes of surgically treated patients with isolated TR.

The purpose of this study is to ultimately evaluate long-term outcomes of this patients population and estimate the impact of baseline staging on long-term outcomes.
