Isolated Coronary Artery Fistula in Fetal Heart: Case Reports and Literature Review.

We report two cases of prenatally diagnosed isolated coronary artery fistula. The first fetus had a fistulous communication between the left circumflex coronary artery and the right atrium. The second fetus had right coronary artery to left ventricle fistula. In addition, we have also reviewed previously published reports on prenatally diagnosed coronary artery fistulae, focusing on their clinical profiles, outcome and postnatal treatment.
