Key result
Percutaneous BMS re-implantation successfully treats late in-stent coronary aneurysm without recurrence at 10 months.
Why the study?
Coronary arterial aneurysm is a rare complication after stent implantation, especially after bare metal stents, and optimal treatment strategies are unclear.
Case Report (n=1)
Percutaneous re-implantation of a bare metal stent can be a successful treatment strategy for late in-stent coronary arterial aneurysms.

May support bare metal stent re-implantation for select late in-stent aneurysms; hypothesis-generating case report leaves broader adoption open.
Development of coronary arterial aneurysm (CAA) is a rare complication after stent implantation, and even more uncommon after bare metal stents (BMS) compared with drug eluting stents. The case is here presented of a 55-year-old male with in-stent CAA, which developed 8 months after BMS implantation. The patient was treated with percutaneous re-implantation of BMS and at the clinical follow-up examination, 10 months after this treatment, there were no problems on the coronary angiography and the patient had no complaints. The treatment strategy is not clear for CAAs, so must be decided after consultation between the cardiologist and cardiac surgeon. BMS re-implantation can be a successful treatment.

Emre Özdemir (2019) conducted a case report in Late coronary arterial aneurysm after bare metal stent implantation (n=1). Percutaneous re-implantation of bare metal stent was evaluated on Resolution of coronary aneurysm and absence of symptoms. Percutaneous re-implantation of a bare metal stent successfully treated a late in-stent coronary aneurysm, with no recurrence or symptoms observed at 10-month follow-up.
