What pathology can a left atrial myxoma mimic?

Atrial myxomas can lead to many complications and can also mimic mitral stenosis, infective endocarditis, and other vascular diseases associated with systemic embolization.

Can atrial myxomas mimic mitral valve disease?

Myxomas can cause a pulmonary or systematic embolism, depending on the position of the tumor in the heart [2]. It can cause obstruction in the blood flow, mimicking mitral stenosis like in our case or mitral regurgitation as a result of complete blockage of the valve [3, 4].

Why myxoma is common in left atrium?

A myxoma is a benign tumor in the heart most commonly found in the left atrium. About 75% of myxomas are in the left atrium, usually beginning in the wall that divides the lower chambers of the heart (ventricles) and growing into the atrium. Treatment is necessary to avoid metastasis and the formation of clots.

What is a rhabdomyoma?

A rhabdomyoma is a noncancerous (benign) tumor that typically grows in clusters in the heart. Rhabdomyomas are the most common type of cardiac tumors seen in infants and children. Cardiac rhabdomyomas usually grow in the muscles of the left and right ventricles (the lower chambers of the heart).

What is a Fibroelastoma?

ANSWER: Fibroelastomas are formally known as papillary fibroelastomas, or PFEs, and are sometimes called cardiac papillomas. These small, noncancerous tumors develop in the heart — most often on one of the valves located between the heart chambers.

What is a tumor plop?

Physical examination can reveal a “tumor plop” which is an early diastolic low pitched sound just after the S2 heart sound. This is in contrast to the opening snap of rheumatic mitral valve stenosis, which is high-pitched. A tumor plop may be followed by a low pitched diastolic murmur.

How common is left atrial myxoma?

Introduction. A left atrial myxoma is a benign tumor that is relatively rare; however, it can have significant clinical implications. A cardiac myxoma is the most common tumor originating from the heart, and a majority of the time the tumor is attached to the interatrial septum by a relatively thin stalk.

What is tuberous sclerosis?

Tuberous sclerosis, also known as tuberous sclerosis complex, is a rare genetic condition that causes mainly non-cancerous (benign) tumours to develop in different parts of the body. The tumours most often affect the brain, skin, kidneys, heart, eyes and lungs.
