Results: The operative mortality was 4 % (2 pts). 98 % of patients were free of AF upon discharge. Fifteen pts. experienced 32 events of intermittent AF (persistent or paroxysmal), all converted back to sinus rhythm with medications and/or cardioversion. 83% of the AF events were recorded during the first year of follow-up and none in patients with follow-up longer then 24 months (n=14). In a univariate model the only predictor for late AF was early postoperative AF. Atrial size, RHD, AF duration, did not predict late AF. Conclusions: The cryomaze procedure can be performed with high success rate in patients with RHD, enlarged atria, long standing AF and CHF. In our experience arrhythmic events thatwere recorded late in the follow-up but could be converted successfully. Therefore a close follow-up is required to enhance the success rate of the procedure.
