Eisenmenger syndrome


Eisenmenger syndrome is a complication of an uncorrected high-flow, high-pressure congenital heart anomaly leading to chronic pulmonary arterial hypertension and shunt reversal.

The three lesions that account for most cases are:

  • ventricular septal defect (VSD)
  • atrioventricular septal defect (AVSD)
  • patent ductus arteriosus (PDA)

Cardiac imaging is useful in assessing for the presence of an intra-cardiac shunt.
