[Case reports of arteriovenous fistulas of coronary vessels in adulthood].
It is reported on the diagnosis and therapy of arteriovenous fistulae of coronary arteries. With the help of 5 casuistic instances external fistulae could be demonstrated by invasive diagnostic procedures. In three cases the fistulae drained from the left coronary into the pulmonary artery, at the second instance from the right coronary artery into the right ventricle, in the fifth instance from the right coronary artery into the right atrium. In addition to this there were coronary stenoses which needed a bypass. In all cases the tentative diagnoses were confirmed intraoperatively. The indication to operative ligatures of the congenital fistulae is discussed and supported depending upon the picture of the complaint.
