Does an Absent Left Main Lead to a Main Event?

This is a case report of a 29-year-old, male applicant for life insurance who was discovered to have an absence of the left main coronary artery (LMCA), with the left anterior descending coronary artery (LAD) and left circumflex coronary artery (LCX) each arising directly from the left sinus of Valsalva. A brief review of several types of coronary artery anatomic variants will be presented.

Left Sinus Of Valsalva

The congenital anomaly of an intramural left main coronary artery arising in the anatomically correct aortic sinus is very infrequent. Aneurysms involving the sinus of Valsalva rarely arise from the left aortic sinus. We present the clinical features and surgical correction of this rare anomaly along with a short discussion of these congenital malformations.

Left Sinus Of Valsalva

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.
