Trombofilia hereditaria y trombo intracardíaco

Thrombophilia is a haematological condition that predisposes to venous and arterial thromboembolic events. It is also a predisposing factor in intracardiac thrombi in paediatrics, and must be suspected if there are no other factors that predispose to thrombosis. The case is presented on a patient with a history cerebral venous thrombosis, who was diagnosed with thrombophilia due to a homozygote G202010A mutation of the prothrombin gene. She developed a right atrial thrombus, which was treated with anticoagulation and echocardiography monitoring. The importance of performing an echocardiography evaluation is highlighted in patients with thrombophilia.
