Device: VDyne Transcatheter Tricuspid Valve Replacement System
The study investigational device is the VDyne Transcatheter Tricuspid Valve Replacement System which consists of a bioprosthetic implantable tricuspid valve, the VDyne Delivery System, Drop Tether, accessories that facilitate the placement of the valve and the VDyne Retrieval System. The VDyne Valve is deployed by transfemoral implantation within the native tricuspid valve and is implanted under fluoroscopic and transesophageal echocardiography (TEE) guidance, while the heart remains beating, without the use of CPB. The valve is repositionable and fully retrievable intraoperatively. Repositioning allows optimization of the valve position following deployment, and retrieval, with the VDyne Retrieval System, allows use of an alternative valve size or removal of the index VDyne Valve in the event of suboptimal valve delivery or other intraoperative complication.

CLINICAL EXCLUSION CRITERIA (assessed by pre-procedural imaging)
-

CONCOMITANT PROCEDURES
-
Significant coronary artery disease requiring treatment such as symptomatic, unresolved multi-vessel or unprotected left main coronary artery disease.
-
Any planned surgery or interventional procedure within the period of 30 days prior to 30 days following the implant procedure. This includes any planned concomitant cardiovascular procedure such as CABG, PCI, pulmonary vein ablation, left atrial appendage occlusion, septal defect repair, etc
-
Unresolved severe symptomatic carotid stenosis (> 70% by ultrasound)
-
Cardiac resynchronization therapy device or implantable pulse generator implanted within 60 days of planned implant procedure.
-
Permanent pacing leads that will interfere with delivery or implantation of the VDyne Valve.
-
Cardiogenic shock or hemodynamic instability requiring inotropes or mechanical support devices at the time of planned implant procedure
-
Prior tricuspid valve surgery or catheter-based therapy with permanent residual devices implanted that would preclude delivery or implantation of the VDyne Valve (e.g. valve replacement, edge to edge repair.)
-
Severe valvular heart disease requiring intervention other than the tricuspid valve
-
Known significant intracardiac shunt (e.g. septal defect) (PFO's without significant shunts are allowed)
COMORBIDITIES
-
Cerebrovascular accident (stroke, TIA) within 6 months of treatment procedure
-
