Catheter-based closure of the left atrial appendage is an alternative to oral anticoagulation for stroke prevention in patients with atrial fibrillation. The effectiveness of this strategy, as compared with physician-directed best medical care, in patients at high risk for stroke and bleeding is unknown.

In the DZHK-funded CLOSURE-AF-DZHK16 study, it was shown that: Among patients with atrial fibrillation at high risk for stroke and bleeding, left atrial appendage closure was not noninferior to physician-directed best medical care with regard to a composite end point of stroke, systemic embolism, major bleeding, or cardiovascular or unexplained death.
