Successful implantation of left atrial appendage occlusion devices in
two patients with failed surgical left atrial appendage closure
Abstract
Atrial fibrillation (AF) is the common heart rhythm abnormality, with
about 12.1 million US cases and 1.2 million new cases predicted by
2030[1](#ref-0001). AF doubles mortality and raises stroke risk by
2.4 time[2](#ref-0002). Guidelines recommend oral anticoagulation
for non-valvular AF with intermediate or higher thromboembolic risk. If
OAC is contraindicated, percutaneous left atrial appendage closure
(LAAC) is considered. Surgical occlusion is done if patients are already
undergoing cardiac surgery, though outcomes vary.[3](#ref-0003)
. We present two high-stroke-risk AF patients who underwent
surgical LAAC but had incomplete closure, resulting in cerebral ischemic
events. Subsequently, they underwent successful percutaneous LAAC device
closure with complete occlusion.
