Current Management of Anomalous Aortic Origin of a Coronary Artery: A Pan-Canadian Survey.

We found a divergence between current practices and expert consensus guidelines regarding the treatment of asymptomatic left AAOCA with high-risk features. Our survey also revealed a lack of consensus among clinicians regarding the management of asymptomatic patients, very young patients, and those with right-sided AAOCA. Evidence-based criteria derived from sufficiently powered studies remain to be established to standardize AAOCA treatment.
