Abstract:
We present 2 cases of caseous mitral annulus calcification (MAC) in which one patient was asymptomatic whereas the second experienced left hemianopsia. Both patients underwent transthoracic and transesophageal echocardiography exams which revealed severe MAC with a mass consistent with caseous MAC. A mobile component of the caseous MAC was observed in the patient with left hemianopsia. Cardiac computerized tomography angiography confirmed the diagnosis. Considering the high surgical risk of caseous MAC debridement, both patients were treated conservatively with uneventful clinical follow-up.

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...

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...
