Does ablation of the coronary sinus area alter ECG manifestations in a patient with typical counterclockwise atrial flutter?
Alterations of the interatrial connections may play a role in the genesis of atypical ECG manifestations of common type atrial flutter.

Case suggests interatrial connections may shape flutter ECG variants; leaves open mechanistic role and need for prospective studies.
Whether the conduction disturbances of the interatrial connections play a role in the genesis of ECG variants of atrial flutter is almost completely unknown. We present a patient with typical counterclockwise atrial flutter in whom the ablation of the coronary sinus (CS) area during ongoing atrial flutter produced significant ECG changes without alterations in the activation sequence within the right atrium (RA). This case highlights the possible role of alterations of the interatrial connections in the genesis of atypical ECG manifestations of common type atrial flutter.

Zrenner et al. (2000) conducted a case report in Typical counterclockwise atrial flutter (n=1). Ablation of the coronary sinus (CS) area was evaluated on ECG changes and activation sequence within the right atrium. Ablation of the coronary sinus area during ongoing typical counterclockwise atrial flutter produced significant ECG changes without altering the right atrial activation sequence.
