Eligibility

Inclusion criteria

Inclusion criteria: Patients presenting with in-stent restenosis (ISR) in coronary arteries requiring revascularization for percutaneous coronary intervention (PCI).Patients or a legally authorized representative must provide written informed consent to participate in the study.Patients with angiographically confirmed ISR in a previously implanted coronary stent, Suitable for OCT imaging

Exclusion criteria

Exclusion criteria: Severe left ventricular dysfunction (ejection fraction less than 30%). History of a stroke or transient ischemic attack (TIA) within 7 days, or any prior intracranial haemorrhage. Anatomy where the device or OCT catheter are unlikely to be delivered due to tortuosity like CTO lesions. Concurrent participation in another clinical study.

Design outcomes

Primary

MeasureTime frame
Stent expansion ratio as assessed by OCT at the end of the procedure. Stent expansion will be calculated as the minimal stent area (MSA) achieved post-treatment, compared to the reference vessel diameter.Timepoint: At Baseline, 1 Month

Secondary

MeasureTime frame
Procedural Success. Procedural Complications. MACE Extra Modality Procedural Duration Timepoint: At baseline during the index procedure
