PULSTA Transcatheter Pulmonary Valve Pre-Approval Study

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: Heart Diseases; Tetralogy of Fallot; Pulmonary Valve Stenosis; Pulmonary Valve Regurgitation
• Intervention / Treatment: Device: PULSTA TPV System

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.

What is the study measuring?

Primary Outcome Measures

Outcome Measure	Measure Description	Time Frame
Procedural/Device related serious adverse events at 6 months		6 months
Hemodynamic functional improvement at 6 months	Hemodynamic functional improvement is a composite of mean RVOT gradient ≤30 mmHg by continuous wave Doppler and a pulmonary regurgitant fraction <20% by cardiac magnetic resonance (MR)	6 months

Secondary Outcome Measures

Outcome Measure	Measure Description	Time Frame
Procedural / Device related serious adverse events		5 years
Other adverse events		5 years
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.	7 days
Hemodynamic Function	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	Pulmonary regurgitant fraction (PRF) will be assessed via cardiac MRI at 6 months after the PULSTA TPV implantation.	6months
Severity of Pulmonary Regurgitation	Severity of pulmonary regurgitation will be assessed via Doppler echocardiography.	5 years
NYHA functional classification	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.	5 years
Catheter reintervention on TPV	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.	5 years
Reoperation	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.	5 years
Death (All cause / procedural/device-related)		5 years
