In an era of frequent catheter ablation it is essential to understand the mechanism of this arrhythmia and to recognize such atypical flutters.Īblação percutânea de fibrilhação auricular Atypical atrial flutter Catheter ablation of atrial fibrillation Flutter auricular atípico Re-ablation Re-ablação.Ĭopyright © 2016 Sociedade Portuguesa de Cardiologia. What are the risks This procedure is generally safe.
This vein was again ablated successfully and there has been no arrhythmia recurrence to date. Catheter ablation is also used to help control other heart rhythm problems such as atrial flutter and atrial fibrillation. Catheter ablation for atrial flutter This is an invasive procedure performed under local anaesthetic and strong sedatives. Atrial flutter is also associated with a risk of stroke so you may be on a blood thinning medication as a consequence of this. The electrophysiology study confirmed the diagnosis of atypical left flutter and reappearance of electrical activity in the right inferior pulmonary vein. Atrial flutter can occur intermittently or the patient can permanently be in this rhythm. Three years later he again suffered palpitations and atypical atrial flutter was documented. After failure of antiarrhythmic therapy, he underwent catheter ablation, with criteria of acute success.
The authors describe the case of a 51-year-old man, with no relevant medical history, referred for a cardiology consultation in 2009 for paroxysmal atrial fibrillation. It restores the normal regular rhythm of the heart by scarring the tissue in the heart that triggers the abnormal rhythm. This type of flutter is particularly common after pulmonary vein isolation, especially after extensive atrial ablation including linear lesions and/or defragmentation. Ablation for Atrial Flutter What is an ‘ablation’ Ablation (sounds like ah-blay-shun) is a medical procedure used to correct certain heart rhythm problems, such as atrial flutter. Cardiac surgery for structural heart disease (often involving the left atrium) and radiofrequency catheter ablation of atrial fibrillation have led to an increased incidence of regular atrial tachycardias, often presenting as atypical flutters.
