Aneurisma del tabique interauricular asociado a ictus

El aneurisma del tabique interauricular es una deformacion de tipo sacular del tejido delgado situado en la zona del foramen oval, que se mueve libremente hacia la auricula derecha, hacia la izquierda o ambas inclusive, con una excursion mayor de 10 mm. Se trata de una enfermedad rara, que cuenta con una fuerte asociacion con el ictus. Se presento una paciente que ingreso al centro con diagnostico de ictus isquemico cardioembolico, en ausencia de factores de riesgo vascular relevantes y la ausencia de fibrilacion auricular. El ecocardiograma transtoracico y transesofagico confirmaron el aneurisma del tabique interauricular asociado a foramen oval permeable. Se reconocio la asociacion de esta entidad con el ictus cardioembolico, se explicaron los posibles mecanismos implicados en su genesis. Se recomienda tener en cuenta este diagnostico en todo ictus criptogenico por las opciones terapeuticas de las que se dispone.(AU) Atrial septal aneurysm is a sac-type deformation of thin tissue located in the area of the foramen ovale, which is free to move into the right atrium, left or inclusive, with greater excursion of 10 mm. It is a rare disease, which has a strong association with stroke. A patient who was admitted with a diagnosis of cardioembolic ischemic stroke, in the absence of relevant vascular risk factors and the absence of atrial fibrillation was presented. Transthoracic and transesophageal echocardiogram confirmed atrial septal aneurysm associated with patent foramen ovale. The association of this entity with cardioembolic stroke is recognized, the possible mechanisms involved in its genesis is explained. It is recommended to consider this diagnosis in all cryptogenic stroke by therapeutic options available.(AU)
