Transcatheter occlusion of coronary artery fistula in a child

in a male newborn a continuous systolic-diastolic murmur on the left sterna l border was caused by a large coronary artery fistula from the left corona ry artery to the right ventricle. Repeated echocardiographic evaluation rev ealed normal ventricular function and a slight increase in fistula diameter from 3,5 mm in the newborn period to 5 mm at the age of 18 months. Interve ntion of catheterization was carried out electively. Complete occlusion of the fistulas was achieved using a flexible coil delievered with a 4 french catheter without any complication. Echocardiographic follow-up confirmed th e postinterventional angiographic finding of complete occlusion of the fist ula and documented normal ventricular function. Conclusion: Transcatheter occlusion of coronary artery fistulas is safe and feasable even in young children.
