Asymptomatic Left Atrial Myxoma

Abstract

Primary tumors of the heart are extremely rare. The most common is the left atrial myxoma. This article presents a case of large asymptomatic left atrial myxoma in an 80-year-old woman. The patient was admitted to the hospital emergency department after a traffic accident. After a performed trauma scan and an echocardiographic examination, a diagnosis of asymptomatic left atrial myxoma was made. The patient was discharged from the hospital with a referral for a consultation at a cardiac surgery center, which the patient did not attend. The treatment of choice for myxomas is surgical removal. The detection of a myxoma usually is considered as an emergency however the tumor described here has the characteristics of myxoma in the complication-free phase. Given the patient's age, reluctance to undergo invasive surgery, and tumor characteristics, it seems that abandoning invasive management in favor of monitoring the patient's condition may be the preferred therapy.
