title: The operability of patient with pulmonary hypertension judged from hemodynamic changes before and after surgery.
abstract: 1) In congenital heart disease with pulmonary hypertension, the place for surgical correction still remains even with almost systemic PA pressure if R to L shunt ratio on lung scintigram is lower than 25%. 2) The patient with pulmonary hypertension in congenital heart disease younger than 3 years of age has wider acceptability for surgery compared to older patient. 3) In patients with mitral valvular disease, surgical correction seems to be indicated irrespective of PA pressure, if their preoperative U/L are lower than 2.4.
