Primary percutaneous coronary intervention of anomalous origin of a high take-off of right coronary artery arising from ascending aorta with percutaneous cardiopulmonary support in acute myocardial infarction.

Coronary angiography of high take-off right coronary artery (RCA) arising from ascending aorta under percutaneous cardiopulmonary support may be more effective at the site distal to RCA ostium rather than proximal. Guide extension catheters (GECs) may be useful to strengthen backup of percutaneous coronary interventions (PCI) system and to contrast coronary lesions clearly during PCI of these RCAs.
