Abstract

A healthy 8 year old boy was referred to our hospital because of cardiomegaly on the chest X ray. No cardiac murmur was detected on chest examination and normal sinus rhythm was checked by electrocardiogram. The 2-D echocardiogram showed a huge dilated right atrium and a normal tricuspid valve and right ventricle. The findings of cardiac angiogram and MRI was compatible with the isolated giant right atrial aneurysm. For the prevention of atrial arrhythmia and thromboembolism, he underwent successful surgical reduction of the right atrium and cryoablation and the follow-up X ray showed no cardiomegaly.
