Catheter ablation is an effective curative treatment for predominantly macro-reentrant atrial tachycardias occurring late after open heart surgery.
Catheter ablation is an effective treatment for late postoperative atrial tachycardias, which are predominantly macro-reentrant and highly dependent on the specific surgical anatomy and incisions.
Supports ablation for late post-surgical macro-reentrant tachycardias; leaves open randomized confirmation before practice change.
Atrial tachycardias are common after open heart surgery. Most commonly these are macro-reentrant including cavotricuspid isthmus dependent atrial flutter, incisional right atrial flutter and left atrial flutter. Focal atrial tachycardias occur less frequently. The specific type of atrial tachycardia highly depends on the type of surgical incision. Catheter ablation can be very effective, however requires a thorough understanding of anatomy and surgical technique.

Kohári et al. (2014) conducted a review in Atrial tachycardias after open heart surgery. Catheter ablation vs. Pharmacological therapy was evaluated. Catheter ablation is an effective curative treatment for predominantly macro-reentrant atrial tachycardias occurring late after open heart surgery.
