Abstract

BACKGROUND: Atrial fibrillation (AF) is the most common sustained cardiac arrhythmia, and the most common cause of cardioembolic stroke. The left atrial appendage (LAA) is the main source of thrombus formation in patients with AF. Therapies include use of percutaneous LAA closure devices, or surgical LAA occlusion (LAAO). Despite these options, complete closure of the LAA is not always achieved, and residual communication between the LAA and atrium may result in increased thrombus formation. Although studies have analysed the use of percutaneous measures such as coils, plugs, or second occluder device deployment in LAA with peri-device leak (PDL), use of percutaneous occlude devices in surgically occluded LAA is far less studied.

CASE SUMMARY: We present a case of a 79-year-old female patient who underwent LAAO device deployment within a surgically occluded LAA with PDL. She underwent 27 mm LAAO device (WATCHMANTM) deployment and all the P.A.S.S. (Position, Anchor, Size, and Seal) criteria were satisfied. Only 1.4 mm PDL was present. She was continued on apixaban and aspirin post-operatively. Post-operative transoesophageal echocardiogram at 6 weeks demonstrated trivial PDL measuring 1.49 mm. Patient was continued on aspirin and clopidogrel, with discontinuation of apixaban.

DISCUSSION: Percutaneous LAAO device deployment in previously surgically ligated LAA with incomplete exclusion is a potential therapeutic option for patients with AF and a high bleeding risk seeking a minimally invasive strategy, in an attempt to de-escalate anticoagulation therapy.
