A Pilot Study on the Prevention of the Vascular RISK Related to Atrial Fibrillation After Intracranial Hemorrhage by Closing the Left Auricle

Atrial fibrillation (AF) is a frequent heart rhythm disorder, responsible for the formation of cardiac thrombi, which can embolize in the systemic circulation, responsible for strokes (Cerebrovascular accidents). AF increases the risk of stroke and stroke-related disability. Preventing the thromboembolic risk associated with FMD is therefore a public health issue. The reference treatment is oral anticoagulation but this treatment is contraindicated in patients with a history of intracranial hemorrhage. The percutaneous closure of the auricle is a recent technique which makes it possible to exclude this appendix from the left atrium where the majority of thrombi are formed in the framework of the AF. Comparative studies have shown the effectiveness of this technique, appearing to be similar to that of anticoagulation. However, in view of the per-procedural risk, the indication of closure was retained by the health authorities only in the event of a contraindication to oral anticoagulants in patients with non-valvular AF with a high thromboembolic risk. Patients with a history of intracranial hemorrhage are therefore candidates for this technique, but there are few studies where these patients were included. The risk-benefit must be demonstrated over the long term, in terms of ischemic, hemorrhagic recurrence and becoming functional and cognitive.
