Abstract

In this work are reported two cases of anomalous aortic origin of a coronary artery (AAOCA), with the left main coronary artery (LMCA) arising at the right sinus of Valsalva in a 77-year-old woman and in a 79-year-old man submitted to angiography after positive ischemic tests. The origin of the LMCA or the left descendant artery (LDA) from the right sinus of Valsalva has a prevalence of 0.2%, the origin of the circumflex artery (CXA) from the right sinus 0.5%, and the origin of the right coronary artery (RCA) from the left sinus of Valsalva has a prevalence of 0.3%. It is the subgroup of the coronary anomalies that has the greatest potential for clinical repercussions, especially the sudden cardiac death (SCD). We discuss the diagnostic methods and treatment options for this kind of coronary anomaly in symptomatic cases.
