Key result
Transcatheter embolization successfully resolves angina from a rare circumflex-to-intercostal artery fistula.
Why the study?
A rare form of coronary steal syndrome caused by an abnormal connection between the left circumflex coronary artery and intercostal arteries may be missed in patients with typical anginal pain and normal coronary arteries.

Embolization may be considered for rare coronary-intercostal steal syndrome; leaves open efficacy and safety in larger cohorts.
A 60-year-old female patient presented with typical anginal pain on exertion and relieved by rest for about one month. Percutaneous coronary angiography was done and showed an abnormal left circumflex coronary artery connecting to intercostal artery. Embolization of that abnormal connection was done successfully and the patient discharged from hospital after 24 hours. This case shows a new form of coronary steal syndrome. This cause could be missed if not put under the differential diagnosis of typical anginal pain with normal coronary arteries.

H et al. (2020) conducted a case report in Coronary-intercostal steal syndrome (n=1). Embolization of abnormal connection was evaluated on Successful occlusion of the abnormal connection and hospital discharge. Embolization of an abnormal connection between the left circumflex coronary artery and intercostal artery successfully treated a 60-year-old woman presenting with typical anginal pain.
