Abstract:
Objective To observe the bipolar radiofrequency ablation maze procedure (BRAMP) combined with heart valve replacement for rheumatic heart disease (RHD) complicated with atrial fibrillation (AF), and discuss the curative effect of the new operation method. Methods Fifteen patients with RHD complicated with AF were treated with heart valve replacement and BRAMP (treatment group). At the same time, 15 patients with RHD complicated with AF were only heart valve replacement without BR AMP(control group). Results Treatment group were all cured, and they had the sinoatrial rhythm after operation.Followed up 6 months, 14 patients maintained sinus rhythm,one had AF occasionally. In control group, 13 patients had AF after operation,2 patients had the sinoatrial rhythm after operation, but they tumed to AF one or two days later,and amiodarone hydrochloride had no effect to them. The two groups had obvious differences in the length of left atria, the length of left ventricle, the size of the heart, the function of the heart and LVEF before and after operation (P ＜ 0.01 or ＜ 0.05). But in treatment group, the length of left atria and the size of the heart had obvious difference after operation compared with control group [ (31.06 ± 2.28 ) mm vs. (36.16 ±2.23) mm,t = 11.645,P =0.002; (50 ±9)% vs. (56 ± 10)% ,t =8.052,P =0.008].Conclusion Compared with the operation that heart valve replacement without BRAMP,BRAMP is simple and little, should be promising.
