Coronary anomalies are rare congenital malformations that are associated with an increased risk of arrhythmias, ischemic events and sudden death. Many remain asymptomatic throughout the patient’s life, and are diagnosed incidentally by imaging tests. The treatment is necessary when ischemia is confirmed or in the presence of symptoms, and surgical intervention is the method of choice. However, some studies allow percutaneous treatment to be used as an alternative, especially in anomalies of the right coronary artery. In view of this, the objective of this study was to report three cases of congenital malformation of the right coronary artery treated by percutaneous coronary intervention.
