Percutaneous left atrial appendage closure is an invasive option for cardioembolic event prevention and it is indicated for patients presenting non-valvular atrial fibrillation and oral anticoagulation therapy failure or contraindication. There is limited data addressing the technical success of percutaneous left atrial appendage closure in patients with complex anatomy and history of previous atrial septal defect repair surgery. We report a case of left atrial appendage closure performed with the LAmbre™ device (LifeTech Scientific, Shenzhen, China) in a patient with a left atrial appendage of complex anatomy, and history of previous surgery for atrial septal defect repair.
