Intervention type: DRUG
Group type: EXPERIMENTAL
Intervention: Rivaroxaban
Description: Direct oral anticoagulants (DOAC) treatment will encompass any of the approved drugs: Rivaroxaban, Edoxaban, Dabigatranetexilat, and Apixaban (Table 1). The DOAC dosage will be adjusted according to kidney function (Table 1) and may be adjusted during the study period according to potential changes in guideline recommendations or if new-onset AF would occur in the follow-up period. The specific DOAC prescribed will be determined by the treating physician. If the patient has already been prescribed Marevan before the aortic valve intervention, the patient will continue this medication following the procedure as an oral anticoagulant treatment, which is administered according to current guidelines.

Group type: ACTIVE_COMPARATOR
Intervention: Acetylsalicylic acid
Description: Antiplatelets decrease platelet aggregation and inhibit thrombus formation. In NOTION-4 acetylsalicylic acid (75 mg once a day) is used as first line choice. For participants who are allergic to acetylsalicylic acid, clopidogrel (75 mg once a day) will be used. If the patient has already been prescribed Clopidogrel before the aortic valve intervention e.g. due to apoplexia, the patient will continue this medication following the procedure as an antiplatelet treatment, which is administered according to current guidelines.
