Introduction The use of contemporary drug-eluting stents (DES) has significantly improved outcomes of patients with coronary artery disease (CAD) undergoing percutaneous coronary intervention (PCI). cases, the target lesion was in-stent restenosis (ISR). At 1 year, only two (0.5%) subjects presented ischemia-driven TLR.

The prospective, international, multicenter single-arm observational study evaluated the treatment of de novo, restenotic or occluded iliac lesions in 160 patients with Rutherford Class 2-6 peripheral artery disease using the Dynetic-35 cobalt chromium balloon-expandable stent system. At baseline, 12.5% stenosis in the target lesion.

No ischemia. This is a conundrum, because it is clear that the patient is having an acute MI, the ECG is dynamic, but the pain is very mild and there is no ECG evidence of active transmural ischemia. We already know that the ischemia is ongoing, though mild (because of the persistent pain). The culprit was opened and stented.
