Outcome Measures

Primary Outcomes (2)

  • Success rate of auricular clip clipping

    Success rate of auricular clip clipping

    12 months

  • Clinical success rate of auricular clip

    Rate of patients without ischemic stroke, TIA, or systemic embolism 12 months after cardiac and auricular clipping

    12 months

Study Arms (2)

left atrial appendage clip

Cardiac valvular patients complicated with atrial fibrillation need cardiac valvular surgery, according to the patient's wishes, cardiac auricular clamp at the same time

Device: atrial appendage clip

Left atrial appendage treated with conventional methods

Valvular heart disease with atrial fibrillation requires valvular heart surgery and left atrial ligation

Device: atrial appendage clip

Interventions

During cardiac surgery, atrial fibrillation patients were treated with atrial appendage clipping
