Conclusion
Our analysis demonstrated that long-term bepridil administration after CA in patients with persistent AF with an enlarged left atrium did not significantly reduce the rate of recurrent AF after the discontinuation of bepridil. The evaluation of LA reverse remodeling at 6 months after CA by echocardiography may be useful for predicting outcomes after the discontinuation of antiarrhythmic drugs.
