Evaluation of Risk Factors and Outcomes of Isolated Tricuspid Valve Replacement with a Conventional Surgical Approach: A Retrospective Cohort Study

Introduction. Tricuspid valve (TV) disease is substantially less common than mitral or aortic valve disease, and it is commonly missed due to the tolerability of stenosis or regurgitation. Adults seldom have primary tricuspid valve regurgitation, which is linked to rheumatic heart disease, infectious endocarditis, myxomatous valve disease, congenital heart disease, carcinoid syndrome, and/or infiltrative valvopathy. Materials and Methods. The authors examined the Valve Surgery Data Bank retrospectively to identify all patients who underwent TV replacement without concomitant surgeries between 2004 and 2014. In addition, the exclusion criteria suggested that all instances involving solitary valve repair were eliminated. Through visits or phone interviews, long-term follow-up was collected through the end of June 2022 in order to gather information on postoperative occurrences among the patients. The average follow-up time was 10.7 + 2.1 (5-15) years. Results. The overall survival rate was 90.9%. Survival rate was not significantly different between bioprostheses and mechanical ones (log rank p=0.05). The incidence of endocarditis and valvar thrombosis in short-term was higher in the mechanical group than in the biological group, but the frequency of valve malfunction and redo surgery was higher in the replacement group. We found a higher incidence of valvular thrombosis, GI bleeding, and myocardial infarction rate in mechanical valve complications compared to the bioprosthetic group regarding late complications.
