We reported 3 years ago the use of cryoablation in the treatment of a right atrium myxoma arising from the Koch’s triangle. The atrioventricular conduction was successfully preserved. Today, after 3 years follow-up, the patient remains with a conducted sinus rhythm and is free of recurrence. Even if extensive resection of the stack of the myxoma remains the first choice attitude, cryoablation could be considered as a serious second choice alternative.
KeywordsMyxoma Cardiac tumors Koch’s triangle Cryoablation
In the literature, only one case of cryoablation in complement to surgical resection is reported . This case involved a left ventricular myxoma recurrence 2 years after initial surgical resection and the use of cryoablation in complement to surgical resection. Unfortunately, the follow-up of this patient is limited to 1 year. Wang et al.  reported recently in an important series an overall rate of recurrence of 5%. Recurrences of cardiac myxomas after resection have been for a long time mainly attributed to incomplete resection of the myxoma’s pedicle [4, 5]. Nowadays, even if this consideration remains relevant, multicentric myxomas growth is considered as the principal risk factor for recurrence . Shinfeld et al. analyzed the reported cases of recurrent myxomas and observed that up to 57% of them were diagnosed within the first 3 years following initial treatment . Finally, Gerbode et al. reported that myxomas recurrence occurs preferably in men than in women . After all these considerations, we can reasonably state that this 81 years old women will not likely present a local recurrence of the initial myxoma. Though we conclude that even if extensive stack resection remains the golden standard attitude, cryoablation may be considered as a valuable secondary alternative to extensive myxomas stalk resection when this excision is hazardous.
