[Percutaneous mitral commissurotomy associated to sinus venosus atrial septal defect and partially anomalous pulmonary venous connection: a case report].

Lutembacher's syndrome refers to the rare combination of congenital atrial septal defect and acquired mitral stenosis. It is rarely associated to partial anomalous pulmonary venous connection. This condition is treated surgically by mitral commissurotomy or mitral valve operation with concomitant closure of the atrial septal defect with correction of the abnormal pulmonary venous connection.
