Potts-shunt procedure for children with severe pulmonary hypertension

Multicenter, Prospective, and Exploratory Study of Potts-shunt for the Treatment of Pediatric Patients With Severe Pulmonary Hypertension

Not applicable Interventional China National Center for Cardiovascular Diseases · NCT06429579

This study tests if adding the Potts-shunt procedure to standard drug treatment can help children with severe pulmonary hypertension feel better compared to just using the medication alone.

What this trial studies

This multi-center, prospective study evaluates the clinical outcomes of the Potts-shunt procedure in pediatric patients aged 6 months to 18 years suffering from severe pulmonary artery hypertension (PAH). Participants must have undergone standardized drug therapy for at least 6-9 months and still exhibit significant clinical symptoms. The study aims to assess the effectiveness of combining the Potts-shunt procedure with conventional drug therapy compared to drug therapy alone over a three-year period.

Who should consider this trial

Good fit: Ideal candidates are pediatric patients aged 6 months to 18 years with ESC 2022 Group I PAH who have not responded adequately to drug therapy.

Not a fit: Patients with ESC 2022 Group II-V PAH or those with severely compromised right ventricular function may not benefit from this study.

Why it matters

Potential benefit: If successful, this approach could significantly improve the quality of life and clinical outcomes for children with severe pulmonary hypertension.

How similar studies have performed: While the Potts-shunt procedure is a recognized intervention, this specific application in pediatric patients with severe PAH is relatively novel and has not been extensively tested in prior studies.
