The effect of heart valve replacement in the same period of radiofrequency ablation on atrial fibrillation / 中国综合临床

ABSTRACT

Objective To investigate the effectiveness of heart valve replacement in the same period of radiofrequency ablation in the treatment of atrial fibrillation.Methods Eighty-six patients with atrial fibrillation underwent heart valve replacement in the same period of bipolar radiofrequency ablation system according to the maze heart valve replacement operation principle.And optimized the operation method.Results No death occurred during operation.The average ablation time was (23 ± 8) minutes with a range of 16-56 minutes.Sinus rhythm of the heart was restored after surgery in all patients (100％).The long-term success rate was 98.8％ (85/86).Conclusion Our optimization of heart valve replacement in the same period of radiofrequency ablation enhanced the success rate of the operation,simplified the procedures,meanwhile it might need widely application clinically.
