El foramen oval permeable es un defecto estructural cardíaco frecuente en la población general. Su importancia clínica radica principalmente en su asociación con el ictus criptogénico, que ha sido descrita en varios estudios. La evidencia es controvertida y para definir el mejor tratamiento en cada caso es necesario individualizar su rol en el ictus criptogénico y el riesgo de recurrencia del mismo.
SummaryThe patent foramen ovale is a common structural heart defect in the general population. Its clinical magnitude lies in its association with cryptogenic stroke, which has been described in several studies. The evidence is controversial and to define the best treatment choice in each case, it is necessary to identify its role in the cryptogenic stroke and the risk of its recurrence.
Forame oval patente e acidente vascular cerebral criptogênicoResumo O forame oval patente é um defeito cardíaco estrutural comum na população geral. A magnitude clínica deste achado reside na sua associação com o acidente vascular cerebral criptogênico, que tem sido descrito em vários estudos. A evidência é controversa e para definir a melhor escolha de tratamento em cada caso, é necessário identificar o seu papel no acidente vascular cerebral criptogênico e o risco de sua recorrência.
The diagnosis of Brugada syndrome is usually made with a typical ECG pattern. However, different disorders can emulate this pattern (Brugada phenocopies). Pathophysiologic mechanisms underlying this phenomenon remain controversial. We describe the development of type‐1 Brugada ECG pattern associated with extensive coronary steal effect during myocardial perfusion scintigraphy. Proximal occlusion of the right coronary artery and severe proximal stenosis in distally occluded left circumflex artery were confirmed by coronary angiogram. Brugada ECG pattern can be a reversible sign associated with inferior left ventricular and right ventricular ischemia. Its presence during acute ischemia deserves appropriate risk stratification.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
