Cryoablation for a right atrial myxoma arising from the Koch's triangle: a case report.

A 78-year-old caucasian patient with compromised cardiac function presenting recurrent episodes of pulmonary embolism was referred to our center for resection of a voluminous right atrial myxoma arising from the Koch's triangle. To preserve the conduction system, we performed an excision of the myxoma associated with cryoablation of its stalk. This case is of special interest for discussing possibilities of preservation of the atrioventricular conduction system in such situations, provided that the contemporary literature does not propose concrete guidelines.
