Abstract:
A 34-year-old man with sudden palpitations, dyspnea, and chest pain was found to have tachycardia and unilateral pulmonary congestion. Intravenous adenosine restored sinus rhythm. Imaging and pathology confirmed an atrial myxoma with severe mitral regurgitation, requiring surgical excision and mitral valve replacement. This case highlights the complex and rare presentations of cardiac myxomas.

Imbalances in Cardiac Output
CHF can occur due to the failure of either side of the heart. Left-side failure leads to pulmonary congestion—the right side continues to send...

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...
