Brief Summary:
The purpose of this study is to assess the safety and performance of the Caisson Interventional Transcatheter MitralValve Replacement (TMVR) system for the treatment of severe symptomatic MitralValve Regurgitation (MR).

Condition or disease Intervention/treatment Phase
Mitral Valve Regurgitation Device: Caisson TMVR System Not Applicable

Detailed Description:
The treatment guidelines for valvular heart disease indicate that surgical correction of primary mitral valve regurgitation (MR) is a Class I recommendation. Further, recent evidence indicates that valve replacement is at least as effective as repair in both primary and secondary MR patients. However, many patients are not referred for surgery as they are considered to be too high of a risk to undergo on pump, open-heart procedures. Percutaneous aortic valve replacement has made treatment of stenosed aortic valves available to high-risk surgical patients who would have otherwise been medically managed. Percutaneous mitral valve (MV) replacement offers similar advantages. Currently, the only approved percutaneous treatment for MR is MitraClip. MitraClip is limited to a specific population of high risk surgical patients with valvular prolapses that are amenable to repair by the edge to edge technique. The feasibility of percutaneous MV replacement has been shown in animal studies, the implantation of aortic valves at the mitral position, and early evaluations of purpose made transcatheter MVs in humans. To meet this medical need, Caisson Interventional has developed a percutaneous delivery system for a bioprosthetic mitral valve. As with patients with aortic valve (AV) deficiencies, this device can be used to provide needed therapy to patients who might not otherwise receive treatment beyond medical therapy. This study will provide initial information on the safety and performance of this system.

Arm Intervention/treatment
Experimental: Treatment Arm
All eligible patients will be in the treatment arm for the 'Caisson TMVR System' (transcatheter mitral valve replacement) procedure. No control or comparator in this study.
Device: Caisson TMVR System
Transcatheter mitral valve replacement is a percutaneous procedure used to treat mitral valve regurgitation with a prosthetic valve implantation.

Primary Outcome Measures :
  1. Number of patients without Major Adverse Events (MAEs) [ Time Frame: 30 days ]
    Freedom from major adverse events including death, stroke, myocardial infarction and surgical reintervention through 30 days

Secondary Outcome Measures :
  1. Number of patients with successful delivery and implantation of the prosthetic valve (technical success) [ Time Frame: Intraoperative ]
    Successful delivery and retrieval of the transcatheter mitral valve delivery system; deployment and correct positioning (via intraoperative imaging) in the appropriate anatomic location of prosthetic valve with no requirement for additional surgery

  2. Number of living, stroke-free patients with prosthetic valve in place (device success) [ Time Frame: 30 days ]
    Patient is alive, stroke-free, original intended device in place (echo), no mitral valve surgical re-intervention required
