Single-Incision Thoracoscopic Left Atrial Appendage Ligation: First Reported Experience

Atrial fibrillation is an increasingly prevalent entity faced by cardiac surgeons. While oral anticoagulation therapy aims to reduce the risk of thromboembolic events patients may desire to discontinue these medications or develop contraindications to their use. Left atrial appendage ligation permits stoppage of oral anticoagulation while also reducing the risk of cerebrovascular events. This manuscript describes the techniques employed in the first reported successful uniportal/single-incision, thoracoscopic epicardial left atrial appendage ligation.
