Study of the Native Outflow Tract Transcatheter Pulmonary Valve (TPV)

Completed · Not applicable

Conditions studied: Congenital Heart Disease, Tetralogy of Fallot

In brief

The purpose of this early feasibility study is to determine how a new transcatheter pulmonary valve will move and perform once implanted in the right ventricular outflow tract.

Who can join

Age: any. Sex: any. Healthy volunteers: not accepted.

You may qualify if…

• Subject has pulmonary regurgitation as per one or more of the following criteria: Severe pulmonary regurgitation as measured by Doppler echocardiography, or Pulmonary regurgitant fraction ≥ 30% as measured by cardiac magnetic resonance imaging
• Clinical indication for surgical placement of a RVOT conduit or bioprosthetic pulmonary valve per one or more of the following criteria: Subject is symptomatic secondary to pulmonary insufficiency (e.g. exercise intolerance, fluid overload) as classified by the Investigator, or Right ventricular end diastolic volume (RVEDV) ≥ 150 ml/m2
• Subject is willing to consent to participate in the study and will commit to completion of all follow-up requirements

You may not qualify if…

• Anatomy unable to accommodate a 25 Fr delivery system
• Obstruction of the central veins
• Clinical or biological signs of infection including active endocarditis
• Indicated for intervention of stenosis of the branch pulmonary arteries at time of implant
• Positive pregnancy test at baseline (prior to CT angiography and again prior to implant procedure) in female subjects of child bearing potential
• Patients with right ventricular outflow tract obstruction (RVOTO) lesions surgically treated with a right ventricle-to-pulmonary artery conduit implant
• A major or progressive non-cardiac disease (e.g. liver failure, renal failure, cancer) that results in a life expectancy of less than one year
• Planned implantation of the Native Outflow Tract TPV in the left heart
• RVOT anatomy or morphology that is unfavorable for anchoring
• Known allergy to aspirin, heparin, or nickel
• Echocardiographic evidence of intracardiac mass, thrombus, or vegetation
• Pre-existing prosthetic heart valve or prosthetic ring in any position
• Patient is currently enrolled in another investigational device or drug trial that may influence the outcome of this trial.
