Arterio-Venous Fistulae of the Coronary Arteries:A Report of Six Cases

Abstract
Coronary anomalous communications to the heart chambers or its great vessels are a rare disorder, which have become of increasing importance, because many of them can be corrected by surgery. Six cases arc presented where the origin and termination of the fistulous communication have been visualized by selective coronary angiography. The diagnosis is discussed on the basis of clinical and haemodynamic investigations and it is stressed that the conclusive diagnosis can only be reached with selective coronary angiography. Anginal pain is a common symptom of this disorder due to a coronary steal effect. The latter is often compensated until adult age. In the aetiology of angina pectoris coronary arteriovenous fistula is therefore of significance.
