E-page Original Images: Cor triatriatum sinister with secundum atrial septal defect in a patient with recurrent pulmonary infections

A 25-year-old male patient was admitted to our department with effort-related dizziness and palpitation. In his medical history, he had been hospitalized several times due to recurrent pulmonary infections. A systolic murmur of grade 3/6 was heard on cardiac auscultation. Transthoracic echocardiography showed a membrane-like structure resembling a pouch dividing the left atrium into two compartments in 2-dimensional views (Fig. 1 and Video 1. See corresponding video/ movie images at www.anakarder.com). Color-Doppler study showed also a color-flow across the inter-atrial septum from the left to the right side.
