Primary pulmonary vein stenosis (PVS) is a rare condition with high mortality. Early diagnosis, high pulmonary arterial pressure, and bilateral vessel involvement predict poor outcomes, suggesting early lung transplantation consideration.

Area of Science:

  • Pediatric Cardiology
  • Thoracic Surgery
  • Pulmonary Hypertension

Background:

  • Primary pulmonary vein stenosis (PVS) is a rare congenital heart defect with limited understanding of prognostic factors and optimal intervention timing.
  • The condition is associated with a high mortality rate, necessitating research into predictive indicators for patient outcomes.

Purpose of the Study:

  • To identify predictors of outcome in patients diagnosed with primary PVS.
  • To evaluate the impact of age at diagnosis, pulmonary arterial pressure, and vessel involvement on mortality and the need for lung transplantation.

Main Methods:

  • Retrospective analysis of the Pediatric Cardiac Care Consortium database (1982-2002) for 31 patients with primary PVS.
  • Exclusion of patients with other complex cardiac anomalies or prior lung transplantation.

  • Data collection through institutional questionnaires to gather additional clinical information.

    • Main Results:

    • Younger age at diagnosis (16.2 months), higher initial mean pulmonary arterial pressure (>33 mm Hg), and bilateral vessel involvement were significant univariate predictors of lung death (death or lung transplantation).
    • Patients diagnosed at 18 months or younger faced a 76% incidence of lung death.
    • Those with initial mean pulmonary arterial pressures >33 mm Hg had an 88% incidence of lung death.

    Conclusions:

    • Primary PVS has a high mortality rate, even with palliative interventions.
    • Early identification of high-risk factors (young age, elevated pulmonary arterial pressure, bilateral involvement) is crucial for patient management.
    • Lung transplantation should be considered early for high-risk PVS patients due to rapid disease progression and poor outcomes with other interventions.
