Transesophageal echocardiography: detection of an acquired left ventricular-right atrial shunt
1Division of Cardiovascular Diseases and Internal Medicine, Mayo Clinic, Rochester, MN 55905.
Abstract:
Communication between the left ventricle and right atrium has a reported prevalence of less than 1%. Acquired left ventricular--right atrial shunt is caused by chest trauma or valvular surgery. A case of acquired left ventricular--right atrial shunt after aortic valve surgery is reported. The detection was possible by use of echo-Doppler, color flow imaging, and transesophageal echocardiography. Combined use of these modalities and multiple transducer positions when transthoracic echocardiography is used are recommended to make the diagnosis.

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...
