Rare coronary artery reactions after implantation of drug eluting stents

Coronary artery stent fractures are well known and more often described complications of percutane- ous revascularisation1, 2. Coronary artery aneurysms (CAA) after coronary intervention are rare, with a reported incidence of 0.3% to 6.0%, and the most “aneurysms” are in fact pseudoaneurysms. Drug- eluting stents (DES), which locally elute antiproliferative drugs, can dramatically inhibit neointimal growth, thereby suppressing restenosis, but at the same time potentially causing coronary aneurysms. In this presentation our goal is to discuss our already published case of stent fracture and one case of CAA after implantation of DES. First case is a 62-year-old female who was admitted for cardiac catheterization due to positive stress test consistent with anteroseptal ischemia. One year earlier she had undergone percutaneous coro- nary intervention (PCI) with placement of two sirolimus eluting stents to left anterior descent artery. Coronary angiography showing complete stent fracture in the mid-LAD with lateral dislocation of dis- tal fragment, significant focal in-stent restenosis and saccular coronary aneurysm below the fracture level. We decided to place graft stent covering the site of the stent fracture and in-stent restenosis. After the procedure coronary artery aneurysm was completely excluded. Second case is a 70-year-old female who had gone to PCI due to acute myocardial infarction of anterior wall. Everolimus eluting stent (EES) was implanted in LAD. Another EES was implanted in right coro- nary artery (RCA) due to suboclusion. Six months after patient was admitted because of reinfarction in anterior wall. Coronary angiography was performed showing two large CAA of LAD (bifurcation LAD/ first diagonal) and RCA at the site of previously implanted EES and thrombotic occlusion of LAD at the distal portion of EES. Intervention was performed with implantation of bare metal stent distally to EES in LAD. Patient is scheduled for next intervention with intention to exclude aneurysm of RCA with implantation of graft stent and coil embolization to LAD. In conclusion coronary interventions are valid treatment options, but further investigation is neces- sary to determine natural history, and best therapies for DES-associated CAA and stent fractures.
