Recurrent atrial myxoma, right atriotomy, and sinus node dysfunction: A case of interdisciplinary care

Primary cardiac tumors are rare, and atrial myxomas represent about half of the benigntumors encountered. When found, definitive treatment is surgical resection. Followingresection 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 moredisruption 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 caseof a woman with a recurrent left atrial myxoma who developed sinus node dysfunction afterresection and discuss her clinical management.
