Novel Observations and Approaches for Left Main Coronary Artery Atresia: How Do We Learn to Manage an Incredibly Rare Condition?

Congenital coronary anomalies are rare enough, and left main coronary artery atresia (LMCOA) is thought to account for 0.1%-0.4% of these—so it really is a very uncommon disease. There are a total of 50 recorded cases of the condition in children in the world literature, 1 Alsalehi M. Jeewa A. Wan A. Contreras J. Yoo S.J. Laks J.A.
