Abstract:
A 32-year-old woman was admitted to our institution for further evaluation of aortic stenosis. Diagnosis of severe aortic stenosis was made by transthoracic echocardiography. Transesophageal echocardiography, live three-dimensional echocardiography and cardiovascular MRI allowed precise evaluation of valve morphology. Interestingly, valve morphology was unicuspid unicommissural with a posterior funnel-shaped valve opening. Surgical inspection during valve replacement confirmed the diagnosis of an unicuspid aortic valve. This case report highlights the use of different imaging modalities in characterizing aortic valve morphology.

Types of Echocardiography
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...

Definition and Purpose
An X-ray, or radiograph, is a non-invasive method that uses ionizing radiation to take images of internal structures. It is mainly used in cardiac imaging to examine the heart, lungs, and major blood vessels, aiming to identify abnormalities in the heart's size, shape, and position, such as heart failure, congenital defects, and vascular...
