Outcome Measures

Primary Outcomes (1)

  • Survival rate without any recurrence of atrial tachyarrhythmias in the absence of antiarrhythmic drugs

    Without detections of atrial fibrillation, atrial flutter, or other atrial tachyarrhythmias with a duration of greater than 30 seconds documented by 3-day Holter monitoring in the absence of antiarrhythmic drugs.

    At 12-month after intervention

Secondary Outcomes (5)

  • Survival rate without permanent pacemaker implantation (Key secondary outcome)

    At 12-month after intervention

  • Survival rate without any recurrence of atrial tachyarrhythmias with antiarrhythmic drugs

    At 12-month after intervention

  • Burden of atrial fibrillation

    At 12-month after intervention

  • Major adverse events

    At 12-month after intervention

  • Cardiac function

    At 12-month after intervention

Study Arms (2)

Bi-atrial ablation group

EXPERIMENTAL

Participants in this group will receive mitral valve surgery concomitant with bi-atrial ablation procedure.

Procedure: Bi-atrial ablation

Left atrial ablation group

ACTIVE COMPARATOR

Participants in this group will receive mitral valve surgery concomitant with left atrial ablation procedure.

Procedure: Left atrial ablation

Interventions

This intervention includes mitral valve surgery concomitant with left atrial ablation and right atrial ablation.

Bi-atrial ablation group

This intervention includes mitral valve surgery concomitant with left atrial ablation alone.

Left atrial ablation group

Eligibility Criteria

Age18 Years+
Sexall
Healthy VolunteersNo
Age GroupsAdult (18-64), Older Adult (65+)

You may qualify if:

  • Age ≥ 18 years
  • Diagnosis of persistent atrial fibrillation(AF) or long-standing persistent AF by medical history and Holter monitoring (persistent AF lasting more than 7 days; long-standing persistent AF lasting more than 1 year).
  • Rheumatic mitral valve disease(RMVD) requires mitral valve surgery( RMVD was determined by history of acute rheumatic fever, valve morphology, echocardiographic findings and pathological diagnosis).
  • Consent to surgical ablation of AF

You may not qualify if:

  • Paroxysmal AF
  • Degenerative or ischemic mitral valve disease
  • Evidence of active infection
  • Previous catheter ablation or surgical ablation for AF
  • Surgical management of hypertrophic obstructive cardiomyopathy
  • Absolute contraindications for anticoagulation therapy
  • Left atrial thrombosis (not including left atrial appendage thrombosis alone)
  • Chronic obstructive pulmonary disease(Forced expiratory volume in 1 second (FEV1)\<30% anticipated value)
  • Uncontrolled hypo- or hyperthyroidism
  • Mental impairment or other conditions that may not allow participants to understand the nature, significance, and scope of study
  • Left atrial diameter\>70mm
  • Right ventricular dysfunction (TAPSE\<16) or moderate to severe tricuspid regurgitation or pulmonary artery pressure (estimated by echocardiography) \>60mmHg
  • Coronary artery bypass grafting is required for participants with coronary heart disease
  • Previous cardiac surgery
  • Refuse to participate in this study
