RESUMO
RESUMEN El cierre de la orejuela izquierda mediante un dispositivo facilita la prevención de un accidente cerebrovascular en pacientes con antecedente de fibrilación auricular no valvular y contraindicación para el uso de medicamentos anticoagulantes. Este artículo presenta dos casos de pacientes con historia de fibrilación auricular en el Hospital Calderón Guardia, ambos con el antecedente de sangrado digestivo y contraindicación para la anticoagulación, en los que se logró el cierre de la orejuela izquierda mediante la colocación exitosa del dispositivo AmuletTM, utilizando TAC y Heart Navigator, técnicas de imagen que se están convirtiendo en el estándar de oro de muchos centros internacionales de referencia en cardiología intervencionista.
ABSTRACT 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.

Percutaneous procedures through femoral access in patients with inferior vena cava (IVC) filter may be at risk of complications. We evaluated the feasibility and safety of left atrial appendage closure (LAAC) through femoral access in patients previously implanted with IVC filter. We described the WatchmanTM device implantation in two patients with formal contraindication for oral anticoagulation. First patient had a GreenfieldTM filter and the second one an OpteaseTM filter, and in this patient an attempt to withdrawal the filter immediately before the LAAC procedure failed. A femoral approach was performed in both patients using a 14 Fr sheath. Before crossing IVC filters, venographies did not detect any thrombus. All steps of IVC filter crossing were performed under fluoroscopic guidance. No immediate or intrahospital complications related to the procedure occurred. Herein, we presented two cases of successful LAAC closure with Watchman device in patients with two different kinds of IVC filters.

OBJECTIVE: This registry aimed to describe the safety and feasibility of a single trans-septal (TS) access technique for left intracardiac echocardiography (ICE) guidance of left-atrial appendage (LAA) closure procedure. BACKGROUND: LAA closure is currently accepted as an alternative to oral anticoagulation (OAC) in patients with non-valvular atrial fibrillation (NVAF) who are at high-risk for bleeding. Currently, LAA closure procedure is typically performed under trans-esophageal echocardiogram (TEE) guidance. Although, ICE has the advantage of not requiring profound sedation/anesthesia, ICE-LAA imaging quality is often limited from the right atrium requiring double TS access. METHODS: Twenty-two patients with NVAF underwent LAA closure using the Amplatzer Amulet™ device (St Jude Medical) under ICE guidance from the left atrium. The ICE AcuNav catheter (Biosense Webster) and the Amulet delivery sheath were advanced into the LA through single TS puncture technique. RESULTS: The population was predominately male (59.1%) with a mean age of 74 ± 9.3 years, at high-risk for stroke (mean CHADS2 score of 3.8 ± 1.1) and bleeding (mean HAS BLED score of 3.5 ± 1.3). The Amplatzer AmuletTM device was successfully implanted in all patients. No procedural related complications including device embolization were noted. No major cardiovascular events occurred and all patients were discharged alive. At 30-day follow-up all patients remained alive, free of ischemic stroke and with no residual leak or device thrombus on TEE. CONCLUSIONS: This initial experience suggests that LAA occlusion with the Amplatzer Amulet device using ICE guidance from the left atrium via a single trans-septal technique is feasible and safe.
