  • Major bleeding

    The incidence of major bleeding in the participants will be reported.

    long-term after the procedure.

  • Death

    all-cause death

    long-term after the procedure.

Secondary Outcomes (3)

  • maintenance of sinus rhythm

    after the procedure outside the 3-month blanking period

  • procedure-related complications

    after the procedure.

  • Heart failure rehospitalization

    after the procedure.

Other Outcomes (1)

  • Atrial fibrillation effects on quality-of-life (AFEQT) scores

    at baseline and after the procedure

Study Arms (1)

LAAC plus Catheter ablation

Patients will receive both left atrial appendage closure and catheter ablation of atrial fibrillation for treatment.

Procedure: left atrial appendage closure and catheter ablation

Interventions

Left atrial appendage closure (LAAC) is a treatment strategy to reduce the risk of left atrial appendage blood clots from entering the bloodstream and causing a stroke in patients with non-valvular atrial fibrillation (AF). Catheter ablation is a procedure used to remove or terminate a faulty electrical pathway or pathological sites from sections of the hearts of those who are prone to developing cardiac arrhythmias such as atrial fibrillation, atrial flutter, supraventricular tachycardias (SVT) and Wolff-Parkinson-White syndrome (WPW syndrome). The ablation procedure can be classified by energy source: radiofrequency ablation and cryoablation.

Also known as: left atrial appendage occlusion; radiofrequency ablation
LAAC plus Catheter ablation
