Surgical resection of left atrial myxomas located near the atrioventricular node carries a risk of postoperative complete atrioventricular block requiring pacemaker implantation.
Myxoma resection near the AV node risks persistent complete block requiring pacing; this case leaves open incidence and prevention.
An 80-year-old female was referred to our institution due to transient right upper limb weakness. Transthoracic and transesophageal echocardiography revealed a tumor in the left atrium. The tumor was attached to the posterior wall of the left atrium near the atrioventricular node. Intraoperative pathological examination revealed that the tumor was a myxoma, and complete resection was successfully performed. However, she experienced persistent complete atrioventricular block postoperatively and required pacemaker implantation.
