Registry for patients with severe tricuspid regurgitation after TricValve implantation

Cardiovascular, Renal and haemodynamIc Outcomes in Patients With Severe TrIcuspid Regurgitation After triCvALve System Implantation: an International Registry - CRITICAL INTERNATIONAL REGISTRY

Observational Azienda Ospedaliero, Universitaria Pisana · NCT05820516

This study is collecting information from patients with severe tricuspid regurgitation who are getting a TricValve implant to see how the procedure affects their heart health and overall quality of life.

What this trial studies

This observational study aims to collect data from patients with severe tricuspid regurgitation who are undergoing TricValve implantation across multiple centers in Italy and Europe. It will assess the impact of the procedure on cardiovascular and all-cause mortality, heart failure rehospitalization, renal function, functional capacity, and quality of life. The study will involve a cohort of 100 patients, with evaluations conducted at baseline, discharge, and 30-day follow-up, including clinical, biohumoral, echocardiographic, and hemodynamic data collection.

Who should consider this trial

Good fit: Ideal candidates are adults aged 18 and older with symptomatic severe tricuspid regurgitation and specific hemodynamic criteria.

Not a fit: Patients with mild or asymptomatic tricuspid regurgitation or those not suitable for TricValve implantation will not benefit from this study.

Why it matters

Potential benefit: If successful, this study could improve treatment outcomes and quality of life for patients with severe tricuspid regurgitation.

How similar studies have performed: While this approach is observational, similar studies have shown promise in assessing the outcomes of transcatheter valve interventions.
