PURPOSE: Use of oral anticoagulation (OAC) in patients with a history of intracranial hemorrhage (ICH) is often considered high risk as OAC-related ICH is associated with high mortality rates. Left atrial appendage closure with a WATCHMAN device is an alternative management strategy to OAC to decrease thrombotic risk in atrial fibrillation patients; however use of OAC followed by dual antiplatelet therapy (DAPT) or DAPT therapy alone is required for 6 months post-procedurally. In this study, we examined the safety of WATCHMAN implantation followed by 6 months of anti-thrombotic therapy in patients with a history of ICH.
METHODS: This is a retrospective analysis of 63 patients with a history of ICH prior to WATCHMAN implantation (Group I) and 95 patients without a history of ICH who underwent WATCHMAN placement (Group II). The primary outcome was death, stroke, or major bleeding within 6 months of WATCHMAN placement.
RESULTS: The average CHA2DS2-VASc of Group I was 4.9 ± 1.7 vs 4.7 ± 1.4 for Group II (p = 0.34). The most common type of ICH in Group I was an intracerebral hemorrhage (57%). The median time between ICH and WATCHMAN implantation in Group I patients was 212 days. A total of 19% of Group I patients were managed with DAPT alone post-procedurally vs. 3% in Group II (p < 0.001). Similar to 89% of Group II (p = 0.19), 95% of Group I patients were free of the primary outcome at 6 months. No Group I patients had recurrent ICH within 6 months after WATCHMAN implantation.
CONCLUSION: In a retrospective, multicenter series of patients with a history of ICH prior to WATCHMAN implantation, WATCHMAN placement was performed safely with 6-month outcomes that were similar to patients without a history of ICH, encompassing the time during which a patient with a history of ICH would need antithrombotic therapy to facilitate WATCHMAN placement.
