Abstract

       Introduction: Atrial myxomas are rare cardiac tumours. This case report illustrates a case of myxoma in the right atrium, which is a rare location for this condition.

       Case Presentation: A 55 year old Myanmar (Burmese) man had two syncopes within one week. Cardiac evaluation showed changing cardiac murmur. Right atrial enlargement was obvious on electrocardiogram. Transthoracic echocardiogram revealed an echogenic mass in the right atrium which prolapsed through tricuspid valve. The myxoma was successfully excised, the base of which was attached to the interatrial septum at the lower margin of fossa ovalis.

       Conclusion: In this case report, we emphasize the uncommon site of myxomas in the right atrium. Clinical suspicion will lead to early diagnosis by echocardiogram and surgical excision is the curative treatment.

Keywords: Myxoma, Syncope, Right atrial myxoma.
