![]() Atypical atrial flutter may originate from left atrium on occasion however, it is less common. 93657 Additional linear or focal intracardiac catheter ablation of the left or right atrium for treatment of atrial fibrillation. *Less commonly, atrial fibrillation originates from the right atrium including the superior vena cava or coronary sinus. Non-invasive cardiac radioablation for the treatment of cardiac arrhythmias (e.g. If you have persistent atrial fibrillation (AFib), a type of abnormal heart rate, medications and repeated treatment may not control your symptoms. Success rate is high and complication risk is low.Ītrial flutter ablation can be utilized as an initial rhythm control strategy instead of antiarrhythmic drugs since this procedure is low risk with a high success rate, unlike that of atrial fibrillation where success rates vary and there is a higher complication risk. A CTI line - or cavo-tricuspid isthmus line - is placed to interrupt the reentrant circuit. A single ablation line is created between the inferior vena cava and the tricuspid valve (cavo-tricuspid isthmus ablation) to interrupt the flutter circuit. ![]() In 90 of the cases, it is an anti-clockwise circuit, and in 10 of the cases, a clockwise circuit in the right atrium. Catheter ablation is a minimally invasive technique that treats atrial fibrillation (Afib) by applying radiofrequency energy to the heart muscle to. Overview What is atrial flutter ablation Atrial flutter ablation is a procedure to destroy cells in your heart that are causing atrial flutter, an abnormal rhythm of the heart. ![]() Atrial flutter most commonly occurs in a reentrant circuit around the tricuspid valve - typical atrial flutter or type I.Īblation for this rhythm is easy since it requires only venous access to get to the right heart. Atrial flutter arises from the right atrium. ![]()
