title: [Coronary arteriovenous fistula. Considerations on differential diagnosis].
abstract: Review is made of the literature of coronary arteriovenous fistula, since its first description up to 1975; we mention the most important points treated by each author. Two cases are studied clinically, by entheterization and coronariography. We take into consideration the differential diagnosis with patent ductus arteriosus, ventricular septal defect with aortic insufficiency, and rupture of congenital aneurysm sinus of valsalva to right cavities. The result of these studies is that, if an atypical continous murmur for an arterial duct is present, we may suspect a coronary fistula as a first possibility, since an aneurysm of valsalva's sinus is a rare entity.
