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

Marinakis S, Mircev D, Wauthy P - J Cardiothorac Surg (2013)

Bottom Line: 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.

Figure 2: Per-operative vision of the myxoma in close relationship with the tricuspid valve.

Mentions: The patient was urgently prepared for an excision of the myxoma and a coronary artery bypass grafting of the LAD artery with the left internal mammary artery (LIMA). The operation was performed through median sternotomy under cardiopulmonary bypass with bicaval cannulation and antegrade cold blood cardioplegia. After the coronary artery bypass graft anastomosis, a right atriotomy was performed. Following meticulous dissection of the myxoma, which was in close association with the anterior leaflet of the tricuspid valve, we noted that its stalk originated from the Koch’s triangle (Figure 2).
