简要总结
The MASA Valve Early Feasibility Study (MVEFS) multi-site interventional clinical trial within the United States of America with each center following a common protocol.The objective of the trial is to evaluate the safety and probable benefit of MASA Valve in the indicated subset of patients requiring Right Ventricular Outflow Tract Reconstruction (RVOTR). As an early feasibility study, the purpose is determine the feasibility of success of the device in order to gather early data towards a future pivotal study and/or regulatory clearance submission.
详细描述
The MASA Valve is a bi-leaflet pulmonary valved conduit. The MASA Valve has an ePTFE conduit and ePTFE leaflets fixtured to the conduit with polypropylene suture. The device has a pad-printed design on the outer conduit surface indicating the valve position and direction of flow. .
The MASA Valve is intended to be used to reconstruction the Right Ventricular Outflow Tract (RVOT) and provide a functional pulmonary valve. Once implanted, the MASA Valve provides a pathway for blood from the Right Ventricle (RV) to the Pulmonary Arteries (PAs), while the integrated valve helps to prevent backflow into the RV. The MASA Valve Indications for Use are:
The MASA Valve pulmonary valved conduit is indicated for correction or reconstruction of the right ventricular outflow tract (RVOT) in patients aged less than 22 years with any of the following congenital cardiac malformations:
- Pulmonary Stenosis
- Tetralogy of Fallot
- Truncus Arteriosus
- Transposition of Great Vessels
- Pulmonary Atresia
In addition, the MASA Valve is indicated for the replacement of previously implanted, but dysfunctional, pulmonary valves, valved conduits or conduits, as well as for use in the Ross Procedure when the native RVOT is being used to reconstruct the Aorta.
