A Case of Right Coronary Artery to Left Ventricle Fistula with Progression to Spontaneous Closure: Echocardiographic Findings

ABSTRACT

Coronary artery fistula (CAF) is a rare congenital cardiac anomaly, which mainly drains to the right side heart. As the progression to spontaneous closure in CAF was rare, it needed surgery or catheteric embolization in asymptomatic patients due to the future risk of congestive heart failure, myocardiac infarction or sudden death. With the advent of high resolution two-dimensional and color doppler echocardiography during the past decade, more cases of CAF have been diagnosed and spontaneously closed cases have been increased. Here we report a healthy neonate except heart murmur, who showed a right coronary to left ventricle fistula with progression to spontaneous closure at 11months of age. As the natural course of CAF is still poorly defined and spontaneous closure is increasing, it will be desirable to be followed up regularly by echocardiography in asymptomatic cases, rather than to be corrected surgically.
