Safety of left atrial appendage closure in heart failure patients

Left atrial appendage closure (LAAC) is an intervention aimed at stroke prevention in nonvalvular atrial fibrillation (AF). There is a three‐fold increased risk of stroke in patients with concomitant presence of AF and heart failure (HF). While anticoagulation is effective, only 60% receive it. We aimed at studying the safety of LAAC in HF patients using a national all‐payer database.
