The incidence of primary cardiac tumors is very rare. However, the number of reported cases has recently increased due to the widespread use of echocardiography. This patient was a 67-year-old male whose main complaint was dizziness on standing. Right atrial myxoma was diagnosed by two-dimensional echocardiogram. Because of persistent right heart failure, open heart surgery was performed as a sub-emergency procedure. The myxoma was removed successfully and its weight was 93 g. The site of origin of the tumor was the lateral wall of the right atrium close to the entrance of the inferior vena cava.
