Cor Triatriatum

Cor triatriatum is defined as a membrane within the left atrium, which might lead to restricted pulmonary venous return. Diagnosis is usually achieved by echocardiography, therapy of choice is excision of the membrane. Upon ten new cases, the association with other congenital heart diseases (CHDs), clinical symptoms and the surgical approach are discussed. Eight of ten patients were children, six of them aged<1 year. Additional CHDs included atrial and ventricular septal defects, partial anomalous pulmonary venous return and complex CHD. Surgery was performed in all cases. Prognosis is related to associated CHD.
