Iatrogenic Aortocoronary Arteriovenous Fistula

Natural Coronary Bypass: A Rare Case of Aortocoronary Fistula in a Patient with Three-Vessel Disease

“…Likewise, aortocoronary fistula is an abnormal connection between one or both of the coronary arteries and any segment of aorta. A fistula between the aorta and the coronary artery is extremely rare and is most commonly seen after surgical interventions [4]. We here present a case of aortocoronary fistula in a patient with three-vessel disease.…”

Transcatheter coil embolization of iatrogenic coronary artery–left ventricle fistula after mitral valve replacement

“…While coronary artery fistulas are usually asymptomatic in younger patients, with increasing age, symptoms begin to appear and there may be a rise in the incidence of complications [3]. Acquired causes of coronary fistulas are rare disorders and may develop following coronary atherosclerosis, infection, or trauma (iatrogenic) [4], [5], [6], [7], [8]. Iatrogenic coronary fistulas may be acquired secondary to surgical or nonsurgical interventions [9].…”

Treatment of Iatrogenic Aortocoronary Arteriovenous Fistula with Coronary Covered Stent

“…Iatrogenic aortocoronary arteriovenous fistula resulting from placement of an arterial graft to a cardiac vein is a very rare complication of coronary artery bypass graft operation [ 1 , 2 ]. Most patients present postoperatively with angina as a result of residual ischemia that is due to either an unbypassed artery or a coronary steal syndrome [ 3 ]. We present a case involving grafting of the saphenous to the left posterolateral coronary vein and a new technique to closure fistula with covered stent implantation into saphenous vein graft.…”
