Abstract
Background: Cerebral amyloid angiopathy (CAA) is a common cause of intracerebral haemorrhage (ICH) with a high recurrence risk. Left atrial appendage occlusion (LAAO) is a method for ischaemic stroke prevention in patients with atrial fibrillation (AF), potentially reducing the risk of intracranial bleeding in CAA-associated ICH. We aimed to determine the outcomes of patients with AF with CAA-associated ICH undergoing LAAO.
Methods: We conducted a multicentre study of patients with CAA-associated ICH who underwent LAAO for stroke prevention. We pooled our findings with data from a systematic review of relevant published studies of LAAO for AF in ICH survivors reporting CAA diagnosis.
Results: We included data from two published studies (n=65) with CAA-specific data and our cohort study (n=37), providing a total of 102 participants (mean age 76.2±8.0 years, 74.6% male) with CAA-related symptomatic ICH and AF treated with LAAO. The median follow-up period was 9.4 months (IQR 4.2-20.6). Postprocedural antithrombotic regimens varied between single (73.0%) or dual antiplatelet therapy (16.2%), or direct oral anticoagulant (DOAC) (10.8%), with a median duration of 42 days (IQR 35-74). Postprocedural complications were uncommon, but included transient arrhythmias (2.1%) and non-life-threatening tamponade (2.1%). Pooled incidence rates of ischaemic stroke and ICH during follow-up were 5.16 (95% CI 1.36 to 17.48) and 2.73 (95% CI 0.41 to 13.94) per 100 patient years, respectively.
Conclusions: LAAO followed by short-term antithrombotic therapy might be a safe and effective ischaemic stroke preventive strategy in people with CAA-associated ICH and AF. However, randomised controlled trials are needed to determine how LAAO compares with long-term DOAC in this population.
