Key result
Diagnostic angiography can result in rare catheter-induced left internal mammary artery dissections, a complication likely to increase as more bypass patients require repeat imaging.
Highlights catheter-induced LIMA dissection as a rare complication of diagnostic angiography in patients with prior CABG.
Alerts to rare LIMA dissection risk in post-CABG angiography; leaves open incidence and prevention strategies.
Coronary artery dissection is a well-described but rare complication of diagnostic angiography. With increased numbers of patients undergoing coronary artery bypass grafting, the number of patients undergoing repeat angiography for chest pain should likewise increase. The authors report two cases of catheter-induced left internal mammary (LIMA) dissection and review the existing literature.
