[Pulmonary hypertension and histological findings before and years after surgical treatment of congenital heart disease (author's transl)].

The coincidence of pulmonary hypertension and pulmonary vascular disease was investigated in 186 infants and children with congenital heart disease and left to right shunts. The correlation between pulmonary hypertension and pulmonary vasculopathy was highly significant. Hemodynamic pulmonary hypertension is completely suppressed by early pulmonary artery banding or total correction. Even pulmonary vascular alterations can be reversed by these measures.
