Abstract
BACKGROUND: Favorable 6-month outcomes from the CLASP IID Registry (Edwards PASCAL transcatheter valve repair system pivotal clinical trial) demonstrated that mitral valve transcatheter edge-to-edge repair with the PASCAL transcatheter valve repair system is safe and beneficial for treating prohibitive surgical risk degenerative mitral regurgitation (DMR) patients with complex mitral valve anatomy.
OBJECTIVES: The authors sought to assess 1-year safety, echocardiographic and clinical outcomes from the CLASP IID Registry.
METHODS: Patients with 3+ or 4+ DMR who were at prohibitive surgical risk, had complex mitral valve anatomy based on the MitraClip Instructions for Use, and deemed suitable for treatment with the PASCAL system were enrolled prospectively. Safety, clinical, echocardiographic, functional, and quality-of-life outcomes were assessed at 1 year. Study oversight included a central screening committee, echocardiographic core laboratory, and clinical events committee.
RESULTS: Ninety-eight patients were enrolled. One-year Kaplan-Meier (KM) estimates of freedom from composite major adverse events, all-cause mortality, and heart failure hospitalization were 83.5%, 89.3%, and 91.5%, respectively. Significant mitral regurgitation (MR) reduction was achieved at 1 year (P < 0.001 vs baseline) including 93.2% at MR ≤2+ and 57.6% at MR ≤1+ with improvements in related echocardiographic measures. NYHA functional class and Kansas City Cardiomyopathy Questionnaire score also improved significantly (P < 0.001 vs baseline).
CONCLUSIONS: At 1 year, treatment with the PASCAL system demonstrated safety and significant MR reduction, with continued improvement in clinical, echocardiographic, functional, and quality-of-life outcomes, illustrating the value of the PASCAL system in the treatment of prohibitive surgical risk patients with 3+ or 4+ DMR and complex mitral valve anatomy.
