Key result
Catheter ablation of the mitral isthmus successfully terminated atypical left atrial flutter in a patient with a previous surgical Maze procedure, maintaining sinus rhythm at 9 months.

Catheter ablation using activation and entrainment mapping is an effective strategy for treating atypical left atrial flutter following surgical maze and mitral valve repair.
Extends anecdotal evidence for mitral isthmus ablation post-Maze; hypothesis-generating and requires prospective validation.
Hereby we describe a case of LAF developed after a surgical Maze procedure that demonstrates the importance of a systematic approach to mapping and ablating atypical atrial flutter to prevent a recurrence of symptomatic arrhythmia. In patients with previous cardiac surgery procedures, and in particular after a surgical maze, there are many different potential LA reentry circuits that involve various pathways. Both activation mapping and entrainment mapping were performed in order to identify the critical isthmus of the circuit and to effectively terminate the arrhythmia.

Conti et al. (2017) conducted a case report in Atypical atrial flutter (Left Atrial Flutter) (n=1). Catheter ablation was evaluated on Termination of atrial flutter and maintenance of sinus rhythm. Catheter ablation of the mitral isthmus successfully terminated atypical left atrial flutter in a patient with a previous surgical Maze procedure, maintaining sinus rhythm at 9 months.
