Coronary artery findings. Coronary angiography at diagnosis (A,B) showed an in-stent total occlusion of the bare metal stent implanted to the left anterior descending artery (LAD). There was no visible coronary artery dissection, either in the intravascular ultrasound catheter findings (C) or the final shot of angiography after revascularization (D,E) showing thrombolysis in myocardial infarction flow grade 3. Histological examination of the LAD [(F) (Elastica Van Gieson 40×)] revealed a microscopic coronary artery dissection limited to part of the stent segment. RAO: right anterior oblique, CAU: caudal, and CRA: cranial.
