Angioplasty with stent of the left main coronary artery with abnormal origin in the right anterior sinus and with a retro-aortic trajectory.

The authors report a case of angioplasty with implantation of a stent in an anomalous left main coronary artery arising from the right anterior sinus of Valsalva with a retro-aortic trajectory. The introduction of stenting has made angioplasty of anomalous coronary art eries a possible alternative to surgery with the reserve of a high risk of restenosis when the lesion is distal and situated at a bifurcation.
