VANEGAS JARQUIN, Mauricio José et al. Primera colocación del dispositivo AMPLATZER™ AmuletTM para cierre de orejuela en Costa Rica utilizando Heart Navigator. Rev. costarric. cardiol [online]. 2023, vol.25, n.2, pp.6-10. ISSN 1409-4142.

Closure of the left atrial appendage with a device facilitates the prevention of stroke in patients with a history of nonvalvular atrial fibrillation and a contraindication to the use of anticoagulant medications. This article presents two cases of patients with a history of atrial fibrillation at the Calderón Guardia Hospital, both with a history of digestive bleeding and contraindication to anticoagulation, in whom closure of the left atrial appendage was achieved through successful placement of the AmuletTM device, using CT and Heart Navigator, imaging techniques that are becoming the gold standard in many international reference centers in interventional cardiology.

Palavras-chave : Atrial fibrillation; contraindications to anticoagulation; atrial appendage closure; AmuletTM device; cardiac CT; Heart NavigatorTM; 3D simulation.
