Edwards PASCAL Transcatheter Valve Repair System Pivotal Clinical Trial (CLASP II TR)

March 13, 2024 updated by: Edwards Lifesciences

A Prospective, Multicenter, Randomized, Controlled Pivotal Trial to Evaluate the Safety and Effectiveness of Transcatheter Tricuspid Valve Repair With the Edwards PASCAL Transcatheter Valve Repair System and Optimal Medical Therapy (OMT) Compared to OMT Alone in Patients With Tricuspid Regurgitation

To establish the safety and effectiveness of the Edwards PASCAL Transcatheter Repair System in patients with symptomatic severe tricuspid regurgitation who have been determined to be at an intermediate or greater estimated risk of mortality with tricuspid valve surgery by the cardiac surgeon with concurrence by the local Heart Team

Study Overview

Detailed Description

A Prospective, multicenter, randomized, controlled pivotal trial to evaluate the safety and effectiveness of transcatheter tricuspid valve repair with the Edwards PASCAL Transcatheter Valve Repair System and optimal medical therapy (OMT) compared to OMT alone in patients with tricuspid regurgitation. Patients will be seen for follow-up visits at discharge, 30 days, 3 months, 6 months, and annually through 5 years.
