Comparison of LAA-Closure vs Oral Anticoagulation in Patients With NVAF and Status Post Intracranial Bleeding.

Within the current trial, two novel strategies are tested in a randomized fashion in patients with atrial fibrillation and status post intracranial bleeding. Patients with ICH were usually excluded from the large NOAC trials and were also not representatively included in the large Watchman device trials. On the other hand, registries show that there is a significant proportion of patients with status post ICH that were implanted with a LAA closure device in clinical routine, and also there are those patients treated with NOAC due to their high stroke risk, despite the risk of recurrent ICH.

Both therapies, NOAC and LAA closure are effective in preventing stroke in patients with AF at high risk for stroke. Also, for both therapies there is evidence for prevention of bleedings, especially intracranial bleeding events.

Patients within the LAA closure group will have the chance after successful closure of the LAA to quit oral anticoagulation medication and therefore reduce their lifetime risk for bleeding and recurrent bleeding. Patients in the NOAC group are provided with an excellent protection against stroke and a significant reduced bleeding risk compared to Vitamin K antagonist therapy.

The trial will help to develop data and hopefully guidelines for management of patients with AF and status post intracranial bleedings. It may help to give physicians data to therapy patients post ICH adequately and help to reduce mortality rates in those patients.
