title: Spontaneous complete closure of a congenital coronary artery fistula.
abstract: The first documentation is reported of spontaneous closure of a coronary artery to right ventricle fistula that was demonstrated initially in a 14 month old boy. Over a 4 year period after diagnosis, the characteristic continuous murmur gradually disappeared. When the patient was 5 1/2 years of age, selective coronary arteriography showed normal coronary vessels and circulation. Six other cases of coronary fistula observed during the past 10 years are also reviewed. This study supports the rationale for clinical follow-up rather than obligatory surgical intervention in asymptomatic patients with a small shunt who have no evidence of myocardial dysfunction.
