[A patient with coronaro-pulmonary fistula and acute coronary syndrome - clinical and diagnostic problem].

Coronary fistula is a rare congenital heart disease. Usually it is diagnosed because of mild clinical event and sometimes detected by coronary angiography performed during acute phase of myocardial infarction. When the coronary fistula have an aneurysmatic form, it should be closed due to the risk of rupture and sudden death, especially when volumetric and pressure overload or coronary steal syndrome are present. The closure may be performed invasively or non-invasively; the latter method is prefered in asymptomatic patients.
