CTICasesLeft Atrial Myxoma
Imaging findings
CT and echocardiography demonstrate a large, mobile, lobulated left atrial mass attached to the interatrial septum that prolapses through the mitral valve into the left ventricle during diastole.
Key takeaways
Left atrial myxomas are the most common primary cardiac tumors. They are typically pedunculated, attach to the fossa ovalis, and can prolapse across the mitral valve, causing functional mitral stenosis.
