Infradiaphragmatic total anomalous pulmonary venous connection.

studyof 4 cases of uncoplicated total anomalous pulmlonalry venous drainage, in connection with the systemic circuit is in the region of the porta hepatis, revealed similar clinical and radiologic findings, so that in the fourth case the diagnosis was suspected and confirmed by angiocardiographic study. Mainly due to the obstruction of pulmonary venous outflow, this form of total anomalous pulmonary venous drainage forms a distinct entity and the physiologie disturbance is quite different from those anomalies of the venous return in which the connection with the systemic (irculation is above the diaphragm.
