Feasibility Study of the Tioga TMVR System

Evaluation of Safety and Feasibility of the Tioga TMVR System for Treatment of Mitral Regurgitation

The study is aimed to assess the safety and feasibility of the Tioga TMVR System in treating patients with symptomatic MR (MR>=3+)

Study Overview

• Status: Recruiting
• Conditions: Mitral Regurgitation
• Intervention / Treatment: Device: Tioga TMVR System

Detailed Description

The Tioga TMVR Feasibility Study is a prospective, single-arm, multi-center study with a planned enrollment of up to 30 patients. The Tioga TMVR System is designed to percutaneously replace a patient's diseased native mitral valve with a bioprosthetic valve. The investigational device is intended for transseptal replacement of the mitral valve in patients with symptomatic MR (MR>=3+).

Arms and Interventions

Participant Group / Arm	Intervention / Treatment
Experimental: Patients with Symptomatic MR (MR>=3+); Subjects treated with the Tioga TMVR System	Device: Tioga TMVR System; A bioprosthetic mitral valve, as part of the Tioga TMVR System, is implanted percutaneously in a patient with MR via transfemoral-transseptal access.

What is the study measuring?

Primary Outcome Measures

Outcome Measure	Measure Description	Time Frame
Primary Safety Endpoint	Number of subjects with all-cause mortality, cardiovascular-related hospitalizations, disabling stroke, and/or mitral valve reintervention or reoperation through 30 days post-procedure	From index procedure (Day 0) to 30 days post-procedure
Primary Performance Endpoint	Number of subjects achieving MVARC technical success - all of the following must be present at exit of catheterization lab: Absence of procedural mortality; Successful access, delivery, and retrieval of the device delivery system; Successful deployment and correct positioning of the first intended device; Freedom from emergency surgery or reintervention related to the device or access procedure	At completion of index procedure (Day 0)
