Detection of a small left atrial myxoma: value and limitations of four imaging modalities
Abstract:
Coronary angiography in a 52-year-old woman with angina-type chest pain showed tumor circulation with feeding arteries arising from the circumflex artery. Transthoracic echocardiography and magnetic resonance imaging both failed to show any intracardiac masses. A sessile mass measuring 1.5 cm in diameter attached to the atrial septum was readily detected by transesophageal echocardiography. Histologic analysis confirmed the tumor to be a myxoma. Coronary angiography may provide the first clue to the presence of a small myxoma. Transesophageal echocardiography is the imaging modality of choice for further evaluation.

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...
Imaging Studies for Cardiovascular System III: X-Ray
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...
