Determining the Natural and "Unnatural" History of Anomalous Aortic Origin of a Coronary Artery with an Interarterial or Intraconal or Intermural Course (AAOCA): Establishing a Multi-Institutional Registry


About this study

The purpose of the study is to determine the outcome of surgical intervention versus observation in children and young adults with AAOCA. To do this the plan is to create a registry of AAOCA subjects that will enable us to develop a risk stratification model utilizing a large multi-institutional registry under the auspices of the Congenital Heart Surgeons’ Society (CHSS).
