Iatrogenic aorto-sinus of valsalva fistula: angiographic and cine computerized tomography delineation.
A patient is reported who underwent cardiac catheterization 4 years following coronary artery bypass grafting. Cardiac catheterization revealed the presence of a fistulous tract in the wall of the ascending aorta, originating at the site of aortic anastomosis of a saphenous vein bypass graft and ending in the superior aspect of the right sinus of Valsalva. This complication was felt to have resulted from a inadvertent localized dissection of the aorta during bypass surgery. The fistula was also imaged by ultrafast cine computerized tomography which proved a useful non-invasive method for follow-up examination.
