Coronary artery anomalies may increase the risk of sudden death. Despite awareness of this association with certain congenital heart anomalies such as tetralogy of Fallot and transposition of the great arteries, it is thought to be an infrequent finding in cases of isolated patent ductus arteriosus (PDA). The authors report their experience with coronary anomalies in PDA patients. This study aimed to estimate the incidence of coronary artery anomalies in patients with PDA. The study reviewed 206 angiograms of PDA patients obtained between 1999 and 2011 to determine the origin of the coronary arteries. In 102 angiograms (49.5 %), the origin of the coronary arteries could be adequately visualized. An anomalous origin of coronary arteries was detected in 11 of the 102 patients (10.8 %). Seven of these patients had a single common coronary artery origin (6.8 %). One patient had an aberrant origin of the left coronary artery from the noncoronary sinus, and three patients had an aberrant origin of the right coronary artery: two from the left coronary sinus and one from the noncoronary sinus. These findings suggest that the incidence of coronary artery anomalies in association with an isolated PDA may be considerably higher than expected and previously reported. In view of the increased risk for sudden death with coronary anomalies, a reasonable approach is to determine the coronary artery origin and pathway after the diagnosis of an isolated PDA.
