Left atrial appendage occlusion in patients with spontaneous intracerebral hemorrhage : An observational study
Copyright © 2023. Published by Elsevier Inc..
BACKGROUND: Patients with atrial fibrillation (AF) and intracerebral hemorrhage (ICH) are at high risk of ischemic and recurrent bleeding events. Therefore, the decision of restarting or avoiding anticoagulation is challenging. Left atrial appendage occlusion (LAAO) is an alternative for these patients. However, few data are available about safety of early LAAO and factors associated with ischemic stroke and ICH recurrence.
METHODS: A unicentric, observational, retrospective study including all patients with AF and a previous ICH who underwent LAAO. We analyzed baseline clinical and neuroimaging characteristics, procedural outcomes, post-procedural therapies and long-term follow-up.
RESULTS: Forty patients were included, whose mean age was 76.6 ±7.6 years and 73 % were men. In patients in whom a Magnetic Resonance (MR) was performed (n=22, 55 %), cortical microbleeds were detected in 15 (68 %) and cortical superficial siderosis in one patient. The procedure was successful and safe in 100 % of the patients and it was performed within 30 days of the ICH in 37 % of them. After a median follow up of 46.2 months [26-69], intracranial hemorrhage (ICrH) recurrence occurred in 6 patients (5 ICH and 1 subdural hematoma -SDH-) and the index ICH was lobar in all of them. Ischemic events were significantly lower than expected according to the CHA2DS2-VASc score (7.5 % vs. 16.6 %, p=0.048) and bleeding events were similar to expected by the HAS-BLED score (20 % vs 23.4 %, p=0.63).
CONCLUSIONS: In patients with ICH and AF, early LAAO was found to be safe and associated with a reduction in ischemic stroke. However, recurrent ICH risk remains high, and it appears to be mainly driven by cerebral amyloid angiopathy.
