Abstract

We treated a 57-year-old female patient with an atrial tumor that was widely attached to the atrial septum. The tumor was diagnosed as a cystic tumor of the atrioventricular node (CTAVN). This type of tumor is rare, and its antemortem diagnosis is difficult because it is usually asymptomatic. This tumor may cause sudden death; thus surgical resection is recommended. We performed partial resection instead of total resection to avoid pacemaker implantation.
