About
Although the clinical impact of left atrial appendage (LAA) leaks still requires confirmation, the open pouch with residual flow resulting from incomplete LAA closure may promote blood stagnation and thrombus formation, and increase the risk of thromboembolic events. The main purpose of this trial is to evaluate the safety and efficacy of percutaneous leak closure with detachable vascular coils.
Full description
Therapies locally targeting the LAA via occlusion, exclusion, or excision have emerged as an alternative and effective approach for stroke prophylaxis in AF patients, especially those with OAC contra-indications. Despite mounting evidence of their safety and efficacy in comparison with standard oral therapy, device-related thrombus and incomplete LAA closure resulting in residual, significant leak may occur, potentially hindering an effective stroke prevention. To date, detachable coils have found a wide range of applications for transcatheter occlusion/embolization procedures (e.g., cerebral aneurysms, pulmonary, renal and cerebral arteriovenous malformations, patent ductus arteriosus, endoleaks). The main purpose of this trial is to evaluate the feasibility and efficacy of transcatheter leak closure with detachable coils in patients with evidence of incomplete percutaneous/epicardial LAA exclusion.
