Spontaneous Closure of a Symptomatic Coronary Artery Fistula Just within a Few Days of Newborn Period. (22nd April 2013) - Yilmazer, Murat Muhtar
Abstract We present a rare case of spontaneous closure of a fistula between the left coronary artery and the right ventricle (RV) within a few days of newborn period. A 14‐day‐old male newborn was referred to our clinic for investigation of tachypnea and cardiac murmur. A color flow Doppler echocardiography revealed turbulent flow of a large coronary artery fistula (CAF) between the left coronary artery and the RV. Tachypnea was regressed and repeat echocardiogram showed no CAF related to cardiac chambers after 4 days of admission. The spontaneous closure of CAF was found to be more likely in cases younger than 2 years with small‐sized fistulas opening into the right‐sided structures, especially into the RV. Nevertheless, the spontaneous closure is very rare in cases with significant shunt. To the best of our knowledge, this is the first case with documented spontaneous closure of CAF just within the newborn period.
