Clinical Studies

PARADIGM: PARAvalvular Leak Closure With the Amplatzer Valvular Plug occluDer for Interventional Transcatheter Closure for PVL With Surgical bioloGical and Mechanical Heart Valve (PARADIGM) Rochester, Minn.
The purpose of this study is to demonstrate the safety and effectiveness of the AVP III as a treatment for clinically significant PVLs following surgical implant of a mechanical or biological heart valve implanted in the aortic or mitral position.
SAPIEN M3 System TransCatheter MItral Valve ReplaCement via TransseptaL AccEss (ENCIRCLE) Rochester, Minn.
The purpose of this study is to establish the safety and effectiveness of the SAPIEN M3 System in subjects with mitral regurgitation (MR) who are at high surgical risk.

Evaluation of Perivalvular Leak Repair Rochester, Minn.
The aim of this study is to determine that percutaneous repair of paravavular defect has improved clinical outcomes, survival, reduced the incidence of hemolysis related to the paravalvular leak, and that percutaneous intervention has reduced the overall need for surgical intervention.
Prospective, Single-arm, Early Feasibility Study (EFS) for the Treatment of Subjects with Moderate-Severe or Severe Symptomatic Mitral Valve Regurgitation Using the Innovalve Transseptal Mitral Valve Replacement (TMVR) System (TWIST-EFS) Rochester, Minn.
The purpose of this study is to assess the technical and procedural success of the Innovalve TMVR system when used to treat adult patients with symptomatic moderate-severe and severe mitral regurgitation who are at elevated risk for surgical mitral valve repair or replacement and who are anatomically eligible for a transfemoral catheterization with transseptal approach to the left atrium.
