Clinical Trial Summary

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

Description:

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.

• Age group: 10 Years and older

Eligibility

Inclusion Criteria:

• Body weight greater than or equal to 30 kilograms

Outcome

Type	Measure	Description	Time frame	Safety issue
Primary	Hemodynamic functional improvement at 6month	Hemodynamic functional improvement is defined as mean RVOT gradient =30 mmHg by continuous wave doppler, and a pulmonary regurgitant fraction <20% by cardiac magnetic resonance (MR).	6 months
Primary	Procedural / Device related serious adverse events at 6month		6 months
Secondary	Procedural success	Procedural success is defined as the TPV implant within desired position, Right ventricle-Pulmonary artery (RV-PA) peak systolic pressure gradient <35mmHg by catheter, less mild pulmonary regurgitation by angiography, and freedom from explantation of the TPV at 24 hours post-implant.	5 days
Secondary	Hemodynamic function	Hemodynamic function will be measured including peak RVOT pressure gradient, mean RVOT pressure gradient, RV-PA pressure gradient, RV pressure, cardiac output, cardiac index, RV end-diastolic volume by echocardiography, cardiac MR, or catheterization.	5 years
Secondary	Severity of pulmonary regurgitation		5 years
Secondary	New York Heart Association (NYHA) functional classification		5 years
Secondary	Stent fracture	Stent fracture will be assessed by the investigator through radiography (X-ray, Fluoroscopy).	5 years
Secondary	Catheter reintervention on TPV		5 years
Secondary	Reoperation		5 years
Secondary	Procedural / Device related serious adverse events		5 years
Secondary	Death (all cause / procedural / device-related)		5 years
Secondary	Other adverse events		5 years
Secondary	Pulmonary regurgitant fraction	Pulmonary regurgitant fraction will be measured by cardiac MRI.	6 months
