[The roentgenologic diagnosis of cor triatriatum sinistrum].

Varied in compliance with the presence and size of the septal foramen, existence and location of the atrial shunt and abnormal pulmonary venous connection, the haemodynamic status of the reported 10 cases of cor triatriatum sinistrum might be classified into four types: Pulmonary venous hypertensive, polyemic, cyanotic polyemic and normal. Accordingly, the roentgenologic features of this anomaly manifested differently and mimicked mitral stenosis or atrial septal defect.
