Orthoterminally corrective operation in the presence of severe hypoplasia of a pulmonary artery.

ABSTRACT

Hypoplasia of the pulmonary arteries has been cited as a contraindication to right vertricular bypass operations. We have successfully corrected a lesion in which the left pulmonary artery was severely hypoplastic and have documented a good hemodynamic result postoperatively. Size of pulmonary arteries is less important than pulmonary vascular resistance as a criterion for orthoterminal correction.
