Late occurrence of incessant atrial tachycardia following the maze procedure.

We report a patient with incessant atrial tachycardia and AV nodal reentrant tachycardia tachycardia and AV nodal reentrant tachycardia beginning almost 18 months following a successful maze procedure. Both tachycardias were cured by radiofrequency ablation. We speculate that the right atrial tachycardia may have been related to the maze procedure. Finally, we believe this report should emphasize the importance of careful and long-term follow-up of all patients undergoing the maze procedure. Proper evaluation of the place of this therapy greatly depends on reporting of all short- and long-term complications of this new procedure.
