Restenoses, Coronary

The AV-MDR is a prospective, non-randomized, open-label, multi-center registry. The purpose of the AV-MDR study is to proactively collect and evaluate clinical data on the usage of the devices in scope within their intended use with the aim of confirming safety and performance throughout their expected lifetime, ensuring the continued acceptability of identified risks, detecting emerging risks on the basis of factual evidence, ensuring the continued acceptability of the benefit-risk ratio, and identifying possible systematic misuse or off-label usage such that the intended use can be verified as appropriate.

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.
