| Popis: | We report the case of a rare anomaly of the right coronary artery originated from the middle third of the left anterior descending (LAD) coronary artery with a proximal atheromatous obstructive lesion immediately before the emergence of the right coronary artery (RCA). The patient underwent successful angioplasty with stent implantation in the left anterior descending coronary artery. Only 7 cases of this anomaly of distribution have been reported in the literature, but none of them was treated with percutaneous revascularization. Anomalies of the coronary arteries occur in 1 to 2% of the population, constituting a rare, but important, type of nonatherosclerotic coronary artery disease. These anomalies may cause sudden death on exertion and increase the risk of coronary arterial trauma during surgical procedures. In addition, certain types of anomaly may lead to myocardial ischemia 1 . The single coronary artery (SCA), described as an isolated coronary artery, has no gender predominance, being a rare entity with an incidence of 0.024% when isolated, and of 0.03 to 0.04% when associated with other cardiac abnormalities 2-4 . Its main characteristic is being originated from the aortic root through a single ostium, with no evidence of a second ostium, being then responsible for the irrigation of the entire heart, independently of its distribution 2 . In these cases, proximal atherosclerotic obstructions may have severe consequences for the patient 4 . We report the case of a patient who underwent percutaneous coronary intervention with stent implantation and whose RCA originated from the LAD. The cases of only 7 patients with that anomaly have so far been reported in the literature, but none of them was treated with coronary angioplasty 5 |
