Pre-existing scar in the left atrium (LA) can result in complex circuits, sometimes with narrow channels that can be detected with high-resolution mapping.
Ablation flutter atrial update#
2019 AHA/ACC/HRS focused update of the 2014 AHA/ACC/HRS guideline for the management of patients with atrial fibrillation. Left atrial tachycardias (ATs) most commonly occur after catheter or surgical ablation of atrial fibrillation and in patients with atrial myopathies. 2015 ACC/AHA/HRS guideline for the management of adult patients with supraventricular tachycardia. 2020 updated to the 2016 ACC/AHA clinical performance and quality measures for adults with atrial fibrillation or atrial flutter: A report of the American College of Cardiology/American Heart Association Task Force on Performance Measures. Heidenreich P, Estes III M, Fonarow G, et al. Atrial flutter is important not only because of its symptoms but because it can cause a stroke that may result in permanent disability or death. It occurs when a short circuit in the heart causes the upper chambers (atria) to pump very rapidly. In this review, we describe the anatomic basis for presently performed ablation procedures for atrial flutter, atrial fibrillation, and outflow tract ventricular tachycardia. 2019 ESC guidelines for the management of patients with supraventricular tachycardia. Atrial flutter is a type of abnormal heart rhythm, or arrhythmia. When performing procedures for complex arrhythmia and in high risk patient populations, anatomic knowledge becomes mandatory.
