Abstract:
Because of its greater sensitivity, transesophageal echocardiography (TEE) is often misused as a screening tool for the exclusion of infective endocarditis (IE) in patients with small clinical probability of the disease. This study examined the role of using TEE exclusively at a Canadian tertiary care center for the diagnosis of IE and determined which clinical variables are most often associated with positive or negative echocardiographic results supporting or refuting the diagnosis.

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...
