What are the indications of atrial flutter ablation?
Radiofrequency catheter ablation is a reasonable alternative for patients with atrial flutter in whom medical therapy is undesired, unsuccessful, or poorly tolerated. Given its extremely high sucess rate (95-99%) and very favourable risk profile, it is often considered the treatment of choice in the US.
Can I have atrial fibrillation after flutter abaltion?
Some patients with atrial flutter may have atrial fibrillation before or after flutter ablation. Rates ranging from 11% to 36% have been reported. ablation can terminate atrial fibrillation that is a degenerative rhythm of primary atrial flutter. However, the procedure usually does not cure concomitant atrial fibrillation. In some patients bursts of atrial fibrillation initiates atrial flutter. After flutter ablation these patients may continue to experience short bursts of atrial fibrillation even though they are cured of their atrial flutter. Patients with no history of documented atrial fibrillation are generally informed that they may have atrial fibrillation diagnosed after flutter ablation.
How is common atrial flutter cured?
Advances in catheter ablation therapy have led to a widespread increase in its use in management of arrhythmias. ablation procedure is highly sucessful in treating common atrial flutter and often leads to long term cure. In common (typical) atrial flutter, the narrowest passageway is the low right atrial isthmus. The aim of ablation in this area is to make a complete lesion from the tricuspid valve to the inferior vena cava or eustachian ridge. The sucess rate for atrial flutter ablation is approximately 95-99% (among experienced operators). The risk of complications is extremely rare. Some patients may experience recurrence after initial procedure and may need repeat ablation.
what are the types of atrial flutter?
atrial flutter is the most common reentrant atrial tachycardia and can be classified on the basis of reentry around established anatomic landmarks. Typical, or type I, atrial flutter can occur in either a clockwise or counterclockwise direction. However, both tachycardias have the same anatomic boundaries (The anterior boundary is the tricuspid annulus and the posterior barriers are the crista terminalis and eustachian ridge). In counterclockwise typical atrial flutter, the P waves in the inferior leads have the classic “sawtooth” pattern. In clockwise typical atrial flutter, the P waves in the inferior leads are upright. Because these tachycardias use the same anatomic path, they are grouped together for classification purposes. Atypical atrial flutter is poorly understood at present and may represent a heterogeneous group of atrial arrhythmias. It may mimic typical atrial flutter. However, the anatomic boundaries are undefined. Therefore, attempts at ablation are more difficult, and the success rates are lower than those achieved in common atrial flutter.
