Case report: echocardiographic detection of rare single coronary artery anomaly in a child with an atrial septal defect.

ABSTRACT:

Background

A single right coronary artery (RCA) with the left anterior descending (LAD) and circumflex coronary arteries located in the usual anatomic position and supplied by collaterals is the rarest variant of single RCA.

Case summary

We report a paediatric patient with an incidental finding of single RCA Lipton type RI pattern during assessment for transcatheter device closure of an ostium secundum atrial septal defect (secASD). Transthoracic echocardiography (TTE) revealed a dilated RCA, abnormal flow in the LAD, and no identifiable left main coronary artery. Diagnosis of a single RCA was confirmed with angiography. Dobutamine stress echocardiography revealed no inducible ischaemia. Transcatheter device closure of the secASD was subsequently successfully performed.
