title: [Cor triatriatum with atrial fibrillation as initial symptom in adults].
abstract: Cor triatriatum is a rare congenital heart disease. In its classic form its consists of a fibromuscular perforated membrane which divides the left atrium and obstructs blood flow from pulmonary veins to mitral orifice. Clinical symptoms and signs resemble those of mitral stenosis. Traditionally cor triatriatum was encountered most often in infancy and childhood. We describe the case of a young man with cor triatriatum and atrial fibrillation, with syncope. He was operated on with total resection of the obstructing membrane. Modern echocardiography has made diagnosis more easy. Thus, an increasing number of cases of cor triatriatum are diagnosed in adults with few or no symptoms. Symptoms, diagnosis and treatment are discussed, with emphasis on these patients.
