Abstract Aims  This study aims to provide a contemporary overview of outcomes after tricuspid valve (TV) surgery for functional tricuspid regurgitation (TR). Methods and results  The literature was systematically searched for papers published between January 2005 and December 2017 reporting on clinical/echocardiographic outcomes after TV surgery for functional TR. A random effects meta-analysis was conducted for outcome variables, and late outcomes are visualized by pooled Kaplan–Meier curves. Subgroup analyses were performed for studies with a within-study comparison of suture vs. ring repair and flexible vs. rigid ring repair. Eighty-seven publications were included, encompassing 13 184 patients (mean age: 62.1 ± 11.8 years, 55% females). A mitral valve procedure was performed in 92% of patients. Pooled mean follow-up was 4.0 ± 2.8 years. Pooled early mortality was 3.9% (95% CI: 3.2–4.6), and late mortality rate was 2.7%/year (95% CI: 2.0–3.5), of which approximately half was cardiac-related 1.2%/year (95% CI: 0.8–1.9). Pooled risk of early moderate-to-severe TR at discharge was 9.4% (95% CI: 7.0–12.1). Late moderate-to-severe TR rate after discharge was 1.9%/year (95% CI: 1.0–3.5). Late reintervention rate was 0.3%/year (95% CI: 0.2–0.4). Mortality and overall (early and late) TR rate were comparable between suture vs. ring annuloplasty (14 studies), whereas overall TR rate was higher after flexible ring vs. rigid ring annuloplasty (6 studies) (7.5%/year vs. 3.9%/year, P = 0.002). Conclusion  This study shows that patients undergoing surgery for functional tricuspid regurgitation (FTR) have an acceptable early and late mortality. However, TR remains prevalent after surgery. The results of this study can be used to inform patients and clinicians about the expected outcome after surgery for FTR and can results serve as a benchmark for the performance of emerging transcatheter TV interventions.

Introduction: Surgical repair of functional tricuspid regurgitation (FTR) is increasingly performed, and the techniques are evolving. Annuloplasty is currently the technique of choice, with different techniques yielding varied results, and thus require optimization. Objective: In this study, we sought to compare tricuspid valve function and kinematics after ring annuloplasty and Hetzer’s double orifice repair in an ex vivo model of FTR. Methods: Ten pig hearts were mounted into a right heart simulator, and studied at 70 bpm while maintaining the total volume of working fluid. FTR was created by increasing afterload, which caused acute right ventricular dilation and TV tethering. Tricuspid valve annuloplasty (TVA) was performed with a 26mm MC 3 ring. Hetzer procedure was performed with pledgeted sutures that approximated the anteroposterior and septal annular segments. Flow probes were used to measure FTR, and leaflet kinematics with echocardiography. Results: FTR of 17.7±9.2mL(p<0.0001) after RV dilation. Repair with TVA and Hetzer reduced FTR to 8.8±6.8ml(p=0.7142) and 7.8±6.9ml(p=0.0919), respectively, but did not eliminate it. Septal leaflet excursion angle decreased by 48.1% with FTR (p=0.04 vs. baseline ) . Repair with TVA and Hetzer increased the angle to 17.3±6.7°(p=0.0312) and 21.5±8.3°(vs FTR, p=0.0034), respectively. The Hetzer improved septal leaflet mobility better than TVA (p=0.0145). The posterior leaflet excursion angle decreased by 49.2% compared to baseline to 18.4±10.5° (p=0.0060) and both TVA and Hetzer significantly improved mobility to 33.6±8.4° (p=0.0081) and 31.6±15.6° (p=0.0256), respectively. Anterior leaflet mobility decreased after FTR by 60.7% to 18.1±8.2°. The effect of these repairs on the sub-valvular apparatus was negligible. Conclusion: TVA and Hetzer both reduced regurgitation but did not eliminate it. Septal and posterior leaflet mobility was improved, while the anterior leaflet remained tethered.
