Asymptomatic fistula from a giant aneurysmatic left anterior descending artery to the right ventricular outflow tract

Abstract

Coronary artery fistulas are unusual congenital or acquired coronary artery abnormalities in which blood is shunted into a cardiac chamber, great vessel or other structure, bypassing the myocardial capillary network (Jung et al. in Cardiovasc Ultrasound 5:10, 2007). We present a young adult patient with an asymptomatic fistula from a giant aneurysmatic left anterior descending artery to the right ventricular outflow tract, first diagnosed by echocardiography examination and further confirmed by 128-slice computed tomography coronary angiography.

Left main coronary artery atresia complicated by fistulae between the left anterior descending artery and the right ventricle

“…Management is directed by this evaluation, ranging from conservative to complex cardiac surgery. Previous cases have reported an isolated LMCA atresia4 9 or isolated fistula between the LAD and RV 10. However, to our knowledge this is the first reported case of a combination of two very rare anatomical anomalies, LMCA atresia and a fistula between the LAD and RV.…”
