The hypothesis of the study is, that there is a significant interaction in treatment effect between the OCT pattern of neointima (heterogeneous or homogeneous) and the type of percutaneous coronary intervention (drug-eluting stent or drug-coated balloon) in patients with in-stent restenosis.
Patients with ischemic symptoms and/or evidence of myocardial ischemia
Presence of ≥ 50% restenosis after prior implantation of drug-eluting stents in native coronary vessels.
Availability of an OCT-pullback of the target lesion
Written informed consent by the patient for participation in the study.
Cardiogenic shock
Acute ST-elevation myocardial infarction within 48 hours from symptom onset.
Target lesion located in left main trunk or bypass graft.
Additional coronary intervention planned within 30 days of the procedure.
