Potts-shunt for the Treatment of Pediatric Patients With Severe Pulmonary Hypertension

This is a multi-center, perspective, and exploratory study aimed at evaluating the 3-years clinical outcome of Potts-shunt procedure for pediatric patients with severe pulmonary artery hypertension (PAH). The included criteria are as followed: 1)6 months \< age ≤ 18 years; 2) ESC 2022 Group I PAH; 3) Have received standardized drug therapy for at least 6-9 months and still remain at intermediate to high/high-risk status of the criteria of ESC2022; 4) Presenting with significant clinical manifestations (i.e., progressive symptoms/syncope history/growth and development restriction, etc); 5) Informed consent form signed by the patient and their guardian. The excluded criteria are as followed: 1) ESC 2022 Group II-V PAH; 2) Poor right ventricular function: RVEF \< 25% or RVFAC \< 20%; 3) Deteriorated general condition: requiring ICU resuscitation or ECMO assistance; 4) Pulmonary artery pressure/main arterial pressure ratio \< 0.7; 5) Six-minute walk distance \< 150 meters (only applicable to patients aged 8 and above); 6) No significant improvement in RVEF under triple drug therapy. All of the pediatric patients with severe PAH who attend to pediatric cardiac outpatient clinic and meet the designed included criteria and excluded criteria will be enrolled in this study. All of the participants will be divided into two groups (Potts-shunt combined with conventional drug therapy group and only conventional drug therapy group) according to their individual health status (i.e., some c…
