Selective SVG-RCA Angiogram: Complex Bypass Graft Anatomy

Deciphering complex coronary anatomy can be challenging, particularly in post-CABG patients. CABG surgery using conduits with multiple distal anastomoses has the potential to lead to graft failure, largely related to bypass graft flow dynamics. Recognizing conventional, as well as anomalous, coronary artery patterns in specific angiographic views is paramount in understand-ing elaborate graft anatomies. We present herein an interesting case of complex bypass graft angiography with multiple anastamoses supplying the entire myocardium.
