[Pulmonary hypertension in patients with congenital and acquired heart diseases].

Pathophysiology of pulmonary hypertension in patients with congenital and acquired heart diseases are described. The broken down of the pulmonary hypertension is left ventricular dysfunction and/or left atrial overloading, and high blood flow in pulmonary circuit with intra-cardiac or intra-vascular shunt. There are pulmonary venous, reactive, and arterial hypertension, related with the mechanism. The worsening of pulmonary venous hypertension induces acute hemodynamic pulmonary edema. The high blood flow in the pulmonary circulation due to large shunt develops Eisenmenger syndrome related with aging.
