Abstract

Atrial myxoma is the most common primary cardiac tumor, and surgical removal is the treatment of choice. Atrial flutter-fibrillation is common after the surgical excision of such tumors, whereas sinus node dysfunction is a rare complication. We detected postoperative sinus node dysfunction and atrial tachycardia after the excision of a left atrial myxoma in a 63-year-old woman. The patient underwent the implantation of a permanent pacemaker two weeks after the operation. The patient underwent successful catheter ablation of macroreentrant right atrial tachycardia 16 months after the operation with no recurrence of atrial tachycardia over the next four months.
