Noninvasive diagnosis of congenital left coronary artery to right ventricle fistula by nuclear magnetic resonance imaging

In two children with left coronary artery to right ventricle fistula, nuclear magnetic resonance imaging provided high-quality images of the course of the dilated coronary artery and its termination in the right ventricular apex. The advantages of this noninvasive multiplanar imaging technique for visualization of coronary fistulae and dilated coronary arteries are described. This report represents the first description of coronary artery fistula by nuclear magnetic resonance imaging.
