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

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.

Introduction And Objectives: Multislice computed tomography coronary angiography (MSCT-CA) has been developed in the last years. One of the advantages is to supply information of the lumen and wall of the vessels. The aim was to assess the diagnostic accuracy of MSCT - CA to detect significant coronary stenoses taking as gold standard the invasive coronary angiography (ICA).
