Primary Pulmonary Vein Stenosis: Outcomes, Risk Factors, and Severity Score in a Multicentric Study

Kalfa and colleagues retrospectively evaluated restenosis, pulmonary vein (PV) reoperation, and mortality in patients undergoing operations for primary pulmonary vein stenosis (PPVS). Pulmonary hypertension one month after surgery and the severity of PV stenosis were risk factors for negative outcomes. Additionally, the authors found that outcomes were not different between patients receiving a sutureless repair compared to endovenectomy or patch venoplasty, underscoring the poor prognosis for patients with PPVS regardless of surgical technique.
