PULSTA Transcatheter Pulmonary Valve Pre-Approval Study
March 17, 2024 updated by: Taewoong Medical Co., Ltd.
The PULSTA Transcatheter Pulmonary Valve (TPV) Pre-Approval Study
The purpose of the study is to evaluate the safety and effectiveness of the PULSTA Transcatheter Pulmonary Valve (TPV) System for the treatment of congenital or acquired pulmonary valve stenosis and/or regurgitation who require pulmonary valve replacement.
Study Overview
Status
Active, not recruiting
Conditions
Intervention / Treatment
Detailed Description
The PULSTA TPV is a self-expandable valve with flared-ends to adapt to the larger native right ventricular outflow tract (RVOT) and is using a relatively low profile delivery catheter from knitted nitinol wire backbone and trileaflets made from treated porcine pericardial tissue, and a delivery system, which provides access to the right ventricular outflow tract through blood vessels.
Consecutive subject data should be collected at discharge, 1, 6 months, and 1-5 years post PULSTA TPV implantation.

Procedural Success
Time Frame: 7 days
|
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.
|
7 days
|
Hemodynamic Function
Time Frame: 5 years
|
Hemodynamic function will be assessed including peak RVOT pressure gradient, mean RVOT pressure gradient, right ventricle (RV) end-diastolic volume index by echocardiography or cardiac MR.
|
5 years
|
Pulmonary Regurgitant Fraction
Time Frame: 6months
|
Pulmonary regurgitant fraction (PRF) will be assessed via cardiac MRI at 6 months after the PULSTA TPV implantation.
|
6months
|
Severity of Pulmonary Regurgitation
Time Frame: 5 years
|
Severity of pulmonary regurgitation will be assessed via Doppler echocardiography.
|
5 years
|
NYHA functional classification
Time Frame: 5 years
|
Clinical outcome will be assessed as per the New York Heart Association (NYHA) functional classification t all follow-up visits and will be compared to baseline values.
|

|
Catheter reintervention on TPV
Time Frame: 5 years
|
Catheter re-intervention on PULSTA TPV is defined as any interventional catheter procedure (e.g.
balloon angioplasty) that alters or adjusts, or replaces a previously implanted PULSTA TPV during a 5-year follow-up period, and the frequency will be evaluated.
|

Time Frame: 5 years
|
Reoperation is defined as open surgery that alters or adjusts, or replaces a previously implanted PULSTA TPV during a 5-year follow-up period, and the frequency will be evaluated.
