![]() In patients with chronic or recurrent forms of atrial flutter RF ablation should be considered as a first line therapeutic option. RF ablation is a highly effective and safe procedure for cure of atrial flutter. There were no procedural complications and all patients had normal AV conduction at the completion of the ablation. Supraventricular tachycardia (SVT): If you have SVT, your heart still pumps blood normally. Atrial flutter results in a heartbeat that’s faster than normal and like Afib, increases your risk for blood clots and stroke. Of eight patients with documented clinical atrial fibrillation (in addition to atrial flutter) prior to the procedure, five continued to have atrial fibrillation following the ablation. Ablation, also known as catheter ablation, is a treatment that aims to correct certain types of abnormal heart rhythms by blocking electrical pathways in. Atrial flutter: With this condition, the atria contract to pump blood, but they do it too quickly. This patient underwent a successful repeat ablation procedure. Of the 26 patients with successful ablation, there has been one recurrence of typical flutter (4%) during a mean follow-up period of 5.5 +/- 2.7 months. In one patient with a grossly enlarged right atrium, isthmus block could not be achieved. Successful ablation was achieved in 26/27 patients (96%). In order to demonstrate successful ablation, mapping techniques were employed to show that bi-directional conduction block was present in the low right atrial isthmus. ![]() After confirmation of the arrhythmia mechanism with these techniques, an anatomic approach was used to create a linear lesion between the inferior tricuspid annulus and the eustachian ridge at the anterior margin of the inferior vena cava. To evaluate the success rate, recurrence rate and safety of radiofrequency, (RF) ablation for atrial flutter in a consecutive series of patients with drug refractory chronic or paroxysmal forms of the arrhythmia.Įlectrophysiologic evaluation of atrial flutter included activation mapping with a 20 electrode halo catheter placed around the tricuspid annulus and entrainment mapping from within the low right atrial isthmus. Atrial flutter is a common arrhythmia which frequently recurs after cardioversion and is relatively difficult to control with antiarrhythmic agents.
