Brief Summary

The recurrence rate of atrial fibrillation (AF) after bipolar radiofrequency ablation was about 30%. Besides the factors, left atrium diameter, the duration of AF, NT-proBNP, and ejection fraction(EF), some studies demonstrated that the specific microRNA expression (miRNA1, miRNA19,miRNA23, miRNA409 ) showed the significant change in AF patients compared with normal sinus patients, who underwent catheter ablation. Therefore, the correlation of atrial fibrillation recurrence and above-mentioned microRNA after bipolar radiofrequency ablation remained unclear, although bipolar radiofrequency ablation had high rate of sinus.

Eligibility Criteria

Age14 Years - 70 Years
Sexall
Age GroupsChild (0-17), Adult (18-64), Older Adult (65+)
Sampling MethodProbability Sample
Study Population

Study Population include persistent atrial fibrillation with mitral valve stenosis or regurgitation alone. Surgery procedure is mitral valve repair or replacement. Left atrium appendage was harvested for later tissue miRNA study. Six-month follow-up was performed by holter and echocardiography.

You may qualify if:

  • persistent atrial fibrillation, with alone mitral valve stenosis or regurgitation

You may not qualify if:

  • left atrium more than 60mm ejection fraction less than 30% complicated with other valve disease of aortic valve stenosis or regurgitation
