Abstract:
We describe an adult patient in whom live three-dimensional transthoracic echocardiography illustrated the exact site and full extent of the subaortic membrane as well as the narrow opening within the membrane, indicative of severe stenosis. To our knowledge this has not been reported previously.

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...
