Percutaneous coronary intervention to anomalous right coronary artery and retained piece of guidewire in the coronary vasculature.

The incidence of anomalous origin of the coronary arteries varies between 0.2% and 1.2%; the anomalous right coronary artery accounting for 6--27% of all the cases. To date technical experience on angioplasty in patients with anomalous coronary arteries reported in the literature is limited. A major factor is the selection of the guiding catheter to access the anomalous origin and also to give good support during angioplasty. We report the details of angioplasty in a patient with a similar problem and the dilemma following a fractured segment of the guidewire retained in the coronary vasculature.
