Multi-center Trial of Percutaneous Pulmonary Valve Implantation With Venus-p (Venus-P)

October 28, 2015 updated by: Shanghai Zhongshan Hospital

Multi-center Trial of Percutaneous Pulmonary Valve Implantation Using Venus-P Valve for Patients With Severe Pulmonary Regurgitation and Native Right Ventricular Outflow Tract After Previous Surgical Repair

Venus-P Valve (Venus Medtech, Shanghai, China) is the first self-expandable interventional Pulmonary Valve, which is composed of a Nitinol multilevel support frame with a tri-leaflet porcine pericardial tissue valve, and a 14-22 Fr delivery catheter. The purpose of the multi-center trial is to evaluate the safety and efficacy of the Venus-P Valve for percutaneous pulmonary valve implantation (PPVI) in patients pulmonary regurgitation and native right ventricular outflow tract (RVOT) after surgical repair of RVOT.

Detailed Description

Clinical experience to date with transcatheter pulmonary valve replacement has been limited to two balloon expandable systems, namely the Melody Valve (Medtronic Inc, Minneapolis, MN) and the Sapien valve (Edwards Lifesciences, Irvine, CA). Both valves have undergone clinical trials with good medium-term valve durability. Although both the Melody and the Sapien valves have been used in native outflow tracts with good success , limitations to the extended application of these valves have generally centered on the maximum diameter of the RVOT. Indeed in the majority of patients requiring pulmonary valve replacement (PVR), these balloon expandable systems are not large enough to maintain stable valve position within the dilated native RVOT.Therefore more recent efforts have concentrated on a self-expanding system to provide valve competence despite significant dilation of the native RVOT.

Venus-P Valve (Venus Medtech, Shanghai, China) is the first self-expandable interventional Pulmonary Valve, which is composed of a Nitinol multilevel support frame with a tri-leaflet porcine pericardial tissue valve, and a 14-22 Fr delivery catheter. The purpose of the trial is to evaluate the safety and efficacy of the Venus-P Valve for PPVI in patients pulmonary regurgitation and native RVOT after surgical repair of RVOT.

Phase

Phase

The stage of a clinical trial studying a drug or biological product, based on definitions developed by the U.S. Food and Drug Administration (FDA). The phase is based on the study's objective, the number of participants, and other characteristics. There are five phases: Early Phase 1 (formerly listed as Phase 0), Phase 1, Phase 2, Phase 3, and Phase 4. Not Applicable is used to describe trials without FDA-defined phases, including trials of devices or behavioral interventions.

Participation Criteria

Researchers look for people who fit a certain description, called eligibility criteria. Some examples of these criteria are a person's general health condition or prior treatments.

Eligibility Criteria

Eligibility Criteria

The key requirements that people who want to participate in a clinical study must meet or the characteristics they must have. Eligibility criteria consist of both inclusion criteria (which are required for a person to participate in the study) and exclusion criteria (which prevent a person from participating). Types of eligibility criteria include whether a study accepts healthy volunteers, has age or age group requirements, or is limited by sex.
