Introduction: Tricuspid regurgitation (TR) is a common acquired valvular heart disease. Recently new transcatheter treatment options for severe TR have emerged that could change the management of this condition, which warrants better characterization of this specific patient group.
Objectives: The aim of the study was to describe the clinical and echocardiographic characteristics of patients with severe TR and to evaluate their short- and mid-term prognosis.
Patients and methods: This retrospective, observational single-center study enrolled consecutive patients with severe TR hospitalized between January 2016 and September 2021 in the 1st Chair and Department of Cardiology, Medical University of Warsaw, Poland. The severity of heart failure (HF) was evaluated using New York Heart Association (NYHA) classification. Echocardiographic assessment was performed by experienced sonographer. EuroSCORE II and TRI-SCORE were computed for each patient. 12- and 24-month clinical outcomes were reported.
Results: There were 172 patients [93 female (54.1%)] included. The mean age was 76.4 (± 10.5) years. The most common comorbidities included: atrial fibrillation (84.9%), hypertension (68.0%), chronic kidney disease (54.1%), coronary artery disease (45.3%), diabetes mellitus (30.9%). The median EuroSCORE II and TRI-SCORE values were 4.68% and 14.0%, respectively. The median follow-up was 24 months. The overall mortality was 29.7% at 1 year and 47.3% at 2 years. TR grade, TAPSE <17 mm, TAPSE/SPAP <0.26 and right atrial area were significant factors associated with mortality.
Conclusions: Patients presenting with severe TR are characterized by a large comorbidity burden and poor prognosis, despite intensive heart failure management.
