Abstract:
We describe the echocardiographic features of 4 new cases of a rare atrial septal malformation consisting a double atrial septum with a midline chamber between the left and right atrium. Half of the cases had major left-sided obstructive lesions. Transthoracic, transesophageal, intracardiac, and fetal echocardiographic features of this anomaly are demonstrated. Previous descriptions, embryologic speculations, and clinical considerations are discussed.

Transthoracic Echocardiography (TTE)
TTE is the most common type of echocardiogram which involves placing a transducer on the patient's chest, emitting sound waves to create heart images. TTE is invaluable for evaluating the heart's size, structure, and motion, making it particularly useful for diagnosing...
