Pulsta® Transcatheter Pulmonary Valve Korean Multicenter Study

A Prospective, Multicenter, Single Arm Study to Evaluate the Safety and Effectiveness of Implantation of 'Transcatheter Pulmonary Valve (TPV)' for the Treatment of Congenital Heart Disease With Pulmonary Valve Disease

The purpose of this study is to evaluate the safety and effectiveness of the TPV in patients with pulmonary valve dysfunction.

The TPV is indicated for use in patients with previous undergone replacement of bioprosthetic valve or conduit due to either pulmonary valve atresia, stenosis, regurgitation or a combination of them and present with dysfunctional right ventricular ourflow tract (RVOT) requiring treatment for severe pulmonary regurgitation and/or RVOT conduit obstruction. Consecutive subject data should be collected at discharge, 1, 3, 6 month, and 1-5 years post TPV implantation.

Inclusion Criteria:

• Body weight greater than or equal to 30 kilograms
• Pulmonary regurgitation ≥moderate pulmonary regurgitation (PR) (≥3+) or RVOT conduit obstruction with mean gradient >35mmHg by echocardiography
• pulmonary artery annulus or in situ conduit size of ≥16 and ≤26mm
• Patient willing to provide written informed consent and comply with follow-up requirements

Exclusion Criteria:

• Pre-existing mechanical heart valve in any position
• Obstruction of the central veins (pulmonic bioprosthesis delivery system to the heart)
• Coronary artery compression
• A known hypersensitivity to Aspirin or Heparin
• Immunosuppressive disease
• Active infectious disease (e.g. endocarditis, meningitis)
• Estimated survival less than 6 months
• Female of child-bearing potential who are unable to take adequate contraceptive precautions, are known to be pregnant, or are currently breastfeeding an infant.
