Atrial myxomas are uncommon in the pediatric population but are very important due to pursuant atrioventricular valve obstruction and systemic embolic events. Concerning multiple symptoms ranging from congestive heart failure to neurological deficits, the diagnosis of this disease is complicated. This paper reports a case of left atrium myxoma in a child treated with a surgical excision of the tumor. Surgical excision appears to be curative, as shown in postoperative echocardiogram of this patient. To be precise, an immediate and timely diagnosis of myxoma by echocardiography, allowed the immediate surgical treatment of this rare, benign but potentially lethal cardiac tumor.
