Abstract
Hereditary hemorrhagic telangiectasia, also known as Osler–Weber–Rendu syndrome, is
an autosomal dominant genetic disorder that leads to epistaxis, gastrointestinal bleeding,
iron deficiency anemia, and arteriovenous malformations at the lungs, the liver, and
the brain. However, due to its rarity and its unspecific findings on routine examinations,
diagnosis is not easy unless suspected due to hypoxemia or paradoxical embolism. We
present a case of a 46-year-old-woman with hereditary hemorrhagic telangiectasia and
hypoxemia who presented a myocardial infarction secondary to paradoxical embolism
through pulmonary arteriovenous malformations.
