Atrial Myxoma Differential Diagnoses

Updated: Dec 07, 2015

Diagnostic Considerations

Clinicians should recognize associated valvular damage and be able to differentiate an atrial thrombus from myxoma.

Suggest screening of family members in cases of familial myxoma syndrome. Note that there is a risk of recurrence in the familial myxoma syndrome; therefore, there is a need for family screening with transthoracic echocardiography.

Other conditions to consider in patients with suspected atrial myxoma include the following:

  • Carcinoid heart disease
  • Cerebrovascular accident
  • Collagen vascular disease
  • Left atrial thrombus
