Fjörutíu og þriggja ára gömul kona með sögu um rauða úlfa og fosfólípíð-mótefnaheilkenni leitaði á bráðamóttöku vegna þvoglumælis og greindist með blóðþurrðarslag. Vélindahjartaómun sýndi fyrirferð á míturlokublaði. Eftir frekari uppvinnslu var hún greind með Libman-Sacks hjartaþelsbólgu sem orsakast af skaða á innanþeli samhliða aukinni storkutilhneigingu, og getur myndast af völdum rauðra úlfa eða fosfólípíð mótefnaheilkennis. Libman-Sacks hjartaþelsbólga er smitfrí hrúðurmyndun á hjartaloku og blóðsegarek af völdum þess er sjaldgæft. Slík hjartaþelsbólga er meðhöndluð með blóðþynningu. Einnig er mikilvægt að meðhöndla undirliggjandi grunnsjúkdóm hjartaþelsbólgunnar. Ischemic stroke is a common disease that can stem from multiple different causes, some of which are uncommon. A 43 year old woman with a history of systemic lupus erythematosus and antiphospholipid syndrome visited the emergency department due to dysarthria and was diagnosed with ischemic stroke. Transesophageal echocardiogram showed a mass on the mitral valve. After further workup, she was diagnosed with Libman-Sacks endocarditis, which is caused by endothelium damage along with hypercoagulability, and can form due to systemic lupus erythematosus or antiphospholipid syndrome. Libman-Sacks endocarditis is a nonbacterial thrombotic endocarditis and thromboembolism is rare. It is treated with anticoagulation. It is also important to treat the underlying cause of the endocarditis.3844523119-121isinfo:eu-repo/semantics/openAccessHumansFemaleAdultEchocardiography, TransesophagealAntiphospholipid Syndrome/complicationsMitral Valve/diagnostic imagingAnticoagulants/therapeutic useIschemic Stroke/etiologyTreatment OutcomeLupus Erythematosus, Systemic/complicationsEndocarditis, Non-Infective/etiologyAntiphospholipid syndromeLibman-Sacks endocarditisNonbacterial thrombotic endocarditisSystemic lupus erythematosusGeneral Medicine/dk/atira/pure/researchoutput/researchoutputtypes/contributiontojournal/article10.17992/lbl.2025.03.831
