Spontaneous closure of congestional coronary fistula.

Coronary fistula is a rare congenital anomaly. In the pediatric population they are usually asymptomatic and this entity is suspected from the presence of a continuous murmur. They usually have a favorable course, although rarely they can complicate or occlude spontaneously. Early treatment is generally advised. The authors describe a case of spontaneous closure of congenital right coronary fistula draining into the right ventricle in a twelve-year-old boy and they comment on the therapeutic management of this anomaly.
