Discrete subaortic stenosis: two-dimensional echocardiographic features with angiographic and surgical correlation
Abstract:
Clinical and M-mode echocardiographic features of discrete subaortic stenosis are indirect and nonspecific. Cardiac catheterization and angiography have invariably been necessary for substantiation of the diagnosis. Our experience with two-dimensional echocardiography in 10 patients with discrete subaortic stenosis indicates that this technique is more sensitive than angiography for the recognition and characterization of the obstruction. Although catheterization is superior in determining the severity of obstruction, two-dimensional echocardiography is at least as sensitivie in assessing ventricular hypertrophy and contractility and is a superior technique for appreciation of the morphologic spectrum of the lesion causing discrete subaortic stenosis.

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...
