Atrial septal defects: the role in the development of cerebral circulation disorders caused by paradoxical embolism

Abstract

The article presents a case report of a patient with cardioembolic ischemic stroke (IS), which was the first clinical manifestation of congenital atrial septal defect (ASD), asymptomatic until adulthood. The issues of anatomical classification, restructuring of intracardiac hemodynamics depending on the size and localization of ASD, its role in the development of IS are discussed. The diagnostic algorithm in patients with IS caused by paradoxical embolism is described, the current possibilities of ASD treatment and prevention of related disorders of cerebral circulation are discussed.
