Abstract:
Five patients (four males and one female, aged 29 to 75 years) with subaortic stenoses were examined by transthoracal and transoesophageal echocardiography, including two-dimensional Doppler echocardiography. In only one patient could the obstruction of the left ventricular outflow tract be definitively evaluated by transthoracal echocardiography, whereas by transoesophageal echocardiography the presence of a subaortic membrane could be demonstrated in all patients. The latter method thus proved to be reliable in evaluating the extent of obstruction.

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...
