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 Amulet™ device, using CT and Heart Navigator, imaging techniques that are becoming the gold standard in many international reference centers in interventional cardiology.
Key words: Atrial fibrillation, contraindications to anticoagulation, atrial appendage closure, Amulet™ device, cardiac CT, Heart NavigatorTM, 3D simulation.
Mural endocarditis is an uncommon form of intracardiac infection affecting the non valvular endocardium that can present with complications similar to valvular infective endocarditis. Echocardiography is recommended to confirm the diagnosis when there is a high index of suspicion. Regarding treatment, there is limited evidence about therapeutic strategies in mural endocarditis, however in most reported cases it is recommended to initiate targeted antibiotic therapy associated with early surgical intervention. The following is a clinical case of a 74-year-old male patient with systemic embolic phenomena, in whom a transesophageal echocardiogram documented mural endocarditis in the apex of the left ventricle associated with Staphylococcus aureus bacteremia. This case highlights the importance of a detailed echocardiographic assessment of the cardiac valves and chambers when infective endocarditis is suspected.
Key words: Mural infective endocarditis, transesophageal echocardiogram, Staphylococcus aureus.
