Coronary recanalization due to presumed thrombosis following surgical ligation of a large right coronary artery to right ventricle fistula.
We report angiographic findings in an infant with congestive heart failure due to a large right coronary artery to right ventricular fistula who underwent surgical ligation. Repeat catheterization 2 years later unexpectedly showed extensive thrombosis of the right coronary artery with multiple recanalized channels supplying the right coronary distribution. Review of the literature showed that this may not be an uncommon finding.
