Cardiac magnetic resonance imaging-derived right ventricular volume and function, and association with outcomes in isolated tricuspid regurgitation.
Background: In patients with significant tricuspid regurgitation, cardiac magnetic resonance imaging (CMR) is the preferred method for the evaluation of right ventricular function and volumes. However validated thresholds are lacking.
Aim: The aim of this study was to evaluate CMR assessment of right ventricular volumes in patients with significant (moderate or severe) tricuspid regurgitation, and to define its association with outcomes.
Methods: The PRONOVAL study is a retrospective multicentre study using the clinical data warehouse of Greater Paris University Hospitals (AP-HP). Patients were screened for CMR in the PMSI (Programme de médicalisation des systèmes d'information). Hospitalization reports were analysed by natural language processing to include patients with tricuspid regurgitation. Exclusion criteria were left heart valvular disease, heart transplantation and cardiac amyloidosis. Primary outcome was a combined criterion of death or tricuspid surgery.
Results: Between September 2017 and September 2021, 151 patients with isolated tricuspid regurgitation were screened. Right ventricular function and volumes were available in 86 (57.0%) CMR reports (the complete CMR group). In the complete CMR group, tricuspid regurgitation was severe in 62 patients (72.1%). Median age was 67.0 years (interquartile range 58.0-75.8). Median right ventricular indexed end-diastolic volume was 98.0 mL/m2 (interquartile range 66.8-118.5). At 2-year follow-up, six patients (9.2%) had undergone tricuspid valve surgery, and 12 patients (18.5%) had died. Right ventricular indexed end-diastolic volume was associated with death or surgery at 2years, with an area under the receiver operating characteristic curve of 0.76 (95% confidence interval 0.75-0.77) for a threshold of 119mL/m2.
Conclusion: Right ventricular indexed end-diastolic volume >119mL/m2 was found to be an independent indicator of death or surgery in patients with significant tricuspid regurgitation.
