Primary cardiac tumors are rare, and atrial myxomas represent about half of the benign tumors encountered. When found, definitive treatment is surgical resection. Following resection of these tumors, recurrence is possible, and these patients need regular follow-up. In the case of recurrence, repeat surgical intervention is feasible, but the potential for more disruption in atrial anatomy has to be considered. This could contribute to cardiac arrhythmias, and anticipation of these events is necessary to optimize patient care. We present the case of a woman with a recurrent left atrial myxoma who developed sinus node dysfunction after resection and discuss her clinical management.
