Long-Term Outcomes After Surgical Pulmonary Arterioplasty and Risk Factors for Reintervention

Long-term reintervention for recurrent PA stenosis after patch arterioplasty is common. Patients with bilateral PA stenosis or age younger than 30 days at the time of the index pulmonary arterioplasty are at higher risk for reintervention. These patients may benefit from frequent monitoring or novel approaches to repair.
