==Background==
[[File:Myxoma.jpg|thumb|A myxoma: a gelatinous tumor attached by a narrow pedicle to the atrial septum. The myxoma has an irregular surface and nearly fills the left atrium.]]
*Most common primary cardiac neoplasm
*~80% of myxomas originate in the left atrium, with the remainder in the right atrium<ref>Kuon E, Kreplin M, Weiss W, Dahm JB. The challenge presented by right atrial myxoma. Herz. 2004 Nov;29(7):702-9. doi: 10.1007/s00059-004-2571-7. PMID: 15580325.</ref>

==Clinical Features==
*Cardiovascular symptoms mimicking mitral valve obstruction (e.g., left atrial hypertrophy)
*Increased risk of systemic embolization
*Constitutional symptoms (e.g., fever, weight loss)

==Differential Diagnosis==


==Evaluation==
[[File:PMC4582919 amjcaserep-16-645-g001.png|thumb|(A) Cardiac MRI showing atrial myxoma during systole. (B) Cardiac MRI showing atrial myxoma during diastole. RA – right atrium; RV – right ventricle; LA – left atrium; LV – left ventricle; arrow – myxoma.]]

===Workup===
*Transthoracic echocardiogram
*Transesophageal echocardiogram
*Cardiac MRI 

===Diagnosis===
*Typical location of myxomas is amenable to visualization with TTE

==Management==
*Once presumptive diagnosis made, prompt resection is required due to elevated risk of embolization or cardiac complications<ref>Keeling IM, Oberwalder P, Anelli-Monti M, Schuchlenz H, Demel U, Tilz GP, Rehak P, Rigler B. Cardiac myxomas: 24 years of experience in 49 patients. Eur J Cardiothorac Surg. 2002 Dec;22(6):971-7. doi: 10.1016/s1010-7940(02)00592-4. PMID: 12467822.</ref>

==Disposition==
*Most often admit for further management including potential anticoagulation and resection
