Ablation of Atrial Fibrillation

Atrial Fibrillation Ablation: Volume

2016 – 2020

Atrial fibrillation ablation, also called pulmonary vein antrum isolation (PVAI), is a treatment for patients with atrial fibrillation. The procedure essentially disconnects the pathway an abnormal heart rhythm follows through the heart and prevents atrial fibrillation. Cleveland Clinic performs a large number of atrial fibrillation ablations every year.

Atrial Fibrillation Ablation: Success Rates

Success of atrial fibrillation (AF) ablation is defined as a restored sinus rhythm without recurrence of AF after the patient has stopped taking antiarrhythmic medications for at least 12 months after the procedure. This is influenced by a number of factors, including the length of time the patient has been in AF and the presence or absence of underlying heart disease. In a recent study¹ of 831 patients who underwent AF ablation at Cleveland Clinic, 81% of patients with paroxysmal AF were arrhythmia-free while off antiarrhythmic drugs at 12 months postablation.

Atrial Fibrillation Ablation: Major Complications

2016 – 2020

The overall riskᵃ of major complications associated with atrial fibrillation ablation at Cleveland Clinic from 2016 to 2020 was 1.6%, which is lower than the benchmark rate of 4.5%.²

ᵃThe percentage of overall risk was calculated by dividing the total number of major complications (N = 88) by the total number of atrial fibrillation ablation procedures (N = 5454).
