title: [Chronic cor pulmonale from the echocardiographic viewpoint].
abstract: The morphologic changes of the right heart occurring in chronic cor pulmonale can be detected by means of twodimensional echocardiography. Chronic cor pulmonale can be classified according to semiquantitative echocardiographic criteria using a subcostal window: Stage I: enddiastolic free right ventricular anterior wall greater than 5 mm, the right heart smaller than the left, vena cava inferior less than 10 mm/m2 body surface area, inspiratory collapse greater than or equal to 50%. Stage II: enddiastolic free right ventricular anterior wall greater than 5 mm, the right ventricle in comparison with the left eccentrically enlarged, vena cava inferior like Stage I. Stage III: free right ventricular anterior wall cannot be measured, the right heart in comparison with the left markedly enlarged, vena cava inferior greater than 10 mm/m2 body surface area, inspiratory collapse less than 50%.
