Um raro defeito congênito do miocárdio, conhecido como hipertrabeculação/não-compactação do ventrículo esquerdo (HTVE/NCVE) tem sido ocasionalmente descrito em associação com a formação de trombos com um potencial risco embólico sistêmico, mas sua associação com derrames isquêmicos permanece controversa. Reportamos o caso de um derrame isquêmico em paciente com grave (HTVE/NCVE) e disfunção ventricular como uma possível associação sinérgica etiológica. Na ausência de outras fontes embólicas, uma grave HTVE/NCVE associada com disfunção ventricular poderia constituir uma fonte potencial de embolismo cerebral, especialmente em pacientes com alta suspeita de um mecanismo embólico de derrame sistêmico.

A rare congenital myocardial defect, known as left ventricular hypertrabeculation/non-compaction (LVHT), has been occasionally described associated with thrombus formation with a potential systemic embolic risk, but its association with ischemic strokes remains controversial. We report a case of ischemic stroke in a patient with severe LVHT and ventricular dysfunction as a possible etiologic synergistic association. In absence of other embolic sources, a severe LVTH associated with ventricular dysfunction could constitute a potential source of brain embolism, especially in patients with high suspicion of an embolic mechanism of ischemic stroke.

Most studies evaluating the usefulness of intravenous thrombolysis for acute stroke have excluded subjects aged over 80 years. Therefore there is no evidence to support or contraindícate this therapy in this age group. We report a 93 year-old female subjected to intravenous thrombolysis using tissue plasminogen activator (r-tPA), according to the National Institute of Neurological Disorders protocol. The treatment was successful, there were no hemorrhagic complications and three months later, the patient was practically without any disability. Therefore age is not an absolute contraindication for intravenous thrombolysis in elderly subjects
