Drug-eluting stents (DES) have been introduced to counter the in-stent restenosis associated with bare metal stents. However, the mechanism of action of DES results in a counter-productive effect of coronary artery aneurysm (CAA) formation. Although CAA after the implantation of drug-eluting stents (DES) is a rare occurrence with an incidence rate of up to 0.5%, they are increasingly being detected due to the progressive rise in the usage of DES for the management of coronary artery disease (CAD). Due to the rarity of this condition, evidence and guidelines regarding the management strategies for this condition are still lacking. We present a series of 5 cases of CAA, post-DES implantation, who were all successfully managed with surgical intervention.
