Key result
Catheter ablation guided by three-dimensional electroanatomical mapping is an effective treatment for incisional atrial tachycardia, achieving success rates over 90%.
This review highlights the growing problem of incisional atrial tachycardias following open-heart surgery and discusses the evolving role of mapping and catheter ablation technologies in their management.
Supports 3D mapping-guided ablation for incisional atrial tachycardia; leaves open need for prospective trials on durability.
Tachycardias after atrial incisions represent frequent and serious problem. The majority of them are based on a re-entry electrical activation around a combination of anatomic and surgically created obstacles. Considering significant progress of cardiovascular surgery during the last decade along with potential large amount of open-heart procedures in the near future the number of incisional tachycardias has a tendency to increase. The aim of this work was to quantify the magnitude of the problem, characterize the tachycardias after different surgical operations and to analyze possible interventional treatment strategies. Nowadays evolution of mapping and ablation technologies may contribute to radically treatment of this type of arrhythmias while there are still a lot of issues that should be solved to improve the results of interventional treatment of incisional tachycardias.
