Three-decade follow-up in pulmonary artery ectasia: risk assessment strategy.

We present a 29-year follow-up in a patient with ectasia of the pulmonary trunk and mild valvular stenosis. There was no progression from the first presentation at the age of 15 months until the actual age of 30 years, the z-value of the diameter of the pulmonary trunk remaining almost constant (z-value 22). This indicates that pulmonary dilatation with normal pressure may be a benign disease.
