Abstract

OBJECTIVES: The goal of this study was to assess the applicability of a novel classification of patients with tricuspid regurgitation based on 5 stages and to evaluate outcomes following isolated surgical treatment.METHODS: All patients treated with isolated tricuspid valve repair or tricuspid valve replacement (TVR) from March 1997 to January 2020 at a single institution were retrospectively reviewed. Patients were divided according to a novel clinical-functional classification, based on the degree of regurgitation together with symptoms, right ventricular size and function and medical therapy. A total of 195 patients were treated; however, 23/195 were excluded due to lack of sufficient preoperative data.RESULTS: A total of 172 patients were considered; of these, 129 (75%) underwent TVR and 43 (25%) had tricuspid valve repair. The distribution of patients showed that 46.5% of patients who underwent tricuspid valve repair were in stage 2, whereas 51.9% who underwent TVR were in stage 3. TVR patients were in more advanced stages of the disease, with dilated right ventricles, more pronounced symptoms and development of organ damage. Hospital mortality was 5.8%, in particular 0% in stages 2 and 3 and 15.3% in stages 4 and 5 (P < 0.001). Both intensive care unit and hospital stays were significantly longer in more advanced stages (P < 0.001). Patients in stages 4 and 5 developed more postoperative complications, such as acute kidney injury (3.7-10% in stages 2 and 3 vs 44-100% in stages 4 and 5; P < 0.001) and low cardiac output syndrome (15-50% in stages 2 and 3 vs 71-100% in stages 4 and 5; P < 0.001).CONCLUSIONS: Patients in more advanced stages had higher hospital mortality and longer hospitalizations. Timely referral is associated with lower mortality, short postoperative course and mostly valve repair.
