The Churg-Strauss syndrome (CSS) is a rare systemic disease characteri
sed by vasculitis and peripheral eosinophilia in patients with an atop
ic constitution. Cardiac involvement is an important cause of morbidit
y and mortality yet coronary involvement is very rarely documented. We
report the case of a 38 year old man presenting with fulminant heart
failure. Coronary arteriography demonstrated extensive focal vasculopa
thy consistent with vasculitis. The diagnosis of CSS was established b
ased upon the classical diagnostic criteria and corticosteroid treatme
nt resulted in a spectacular remission of disease activity.
