Why the study?
Studying AAOCA behavior with intravascular ultrasound during the cardiac cycle may help evaluate and quantify dynamic compression severity.
Does intravascular ultrasound (IVUS) help evaluate and quantify the severity of narrowing in anomalous coronary arteries from the aorta during the cardiac cycle?

IVUS may quantify resting systolic compression in AAOCA; hypothesis-generating for risk stratification before prospective validation.
Does intravascular ultrasound (IVUS) help evaluate and quantify the severity of narrowing in anomalous coronary arteries from the aorta during the cardiac cycle?
IVUS can identify and quantify pathological systolic dynamic compression in AAOCA with an intramural segment under resting conditions.
