Coronary Artery Ectasia Associated With Hereditary Hemorrhagic Telangiectasia

Hereditary hemorrhagic telangiectasia (Osler-Weber-Rendu disease) is characterized by a variety of cutaneous, mucosal, and visceral vascular anomalies. A patient with classic hereditary hemorrhagic telangiectasia was shown to have three-vessel coronary artery ectasia without evident atherosclerosis, and association not previously demonstrated. The possibility that coronary artery ectasia may be a manifestation of hereditary hemorrhagic telangiectasia is discussed.
