摘要
An anomalous origin of a coronary artery (AOCA) is the second most common cause of non-traumatic sudden cardiac death in young athletes. Patients with a malignant course of an AOCA of the right coronary artery only need surgical correction when myocardial ischaemia is detected. An AOCA and its malignant or benign course can be detected by coronary angiography, coronary computed tomography or cardiac magnetic resonance imaging. Detection of ischaemia can be more difficult since even a negative maximal-effort stress ECG does not exclude a potential lethal coronary anomaly. Also, there are no case series or trials showing sensitivity or specificity for any form of ischaemia detection for AOCA in the literature. Although not described previously in adults, dobutamine stress echocardiography was previously described in a paediatric population with AOCA. We are the first to describe ischaemia detection by dobutamine stress echocardiography in three adult patients with an AOCA of the right coronary artery who were subsequently referred for surgery.
