NCT ID: NCT05544864 Recruiting - Clinical trials for Coronary Artery Disease

Intracoronary Stenting and Restenosis - Randomized Trial of Drug-eluting Stent Implantation or Drug-coated Balloon Angioplasty According to Neointima Morphology in Drug-eluting Stent Restenosis 5

ISAR-DESIRE5
Start date: September 28, 2022
Phase: N/A
Study type: Interventional

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.

NCT ID: NCT04573660 Recruiting - Clinical trials for Acute Myocardial Infarction

Abbott Vascular Medical Device Registry

AV-MDR
Start date: October 25, 2020
Phase:
Study type: Observational

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.

NCT ID: NCT03600948 Terminated - Clinical trials for Restenoses, Coronary

BIOFLOW-SV All Comers Registry

BIOFLOW-SV
Start date: August 27, 2018
Phase:
Study type: Observational

Assessment of the clinical safety and performance of the Orsiro drug-eluting stent in a real world setting in patients with small vessels with reference vessel diameter ≤2.75 mm.

NCT ID: NCT03588962 Not yet recruiting - Clinical trials for Coronary Artery Disease

Metal Allergy In-Stent Restenosis Study

RESTALL
Start date: October 1, 2018
Phase: N/A
Study type: Interventional

In-stent restenosis remains one of the most challenging problems in patients after coronary artery angioplasty. Angiographically, it is discovered in 10% of the patients after drug-eluting stent (DES) implantation. There are multiple factors causing restenosis, which can be divided into two major groups: first vessel-dependent (based on the vessel's tortuosity, dimensions and lesion's calcification, all leading to suboptimal stent expansion), and second dependent on the inflammatory processes caused by the intervention. Study objectives is the analysis of the possible correlation between allergy to metals utilised during the stent manufacturing (nickel, cobalt, chromium, molybdenum, tungsten) and in-stent restenosis occurence. The angiographic results of stent implantation, and in-stent restenosis will be assessed independently by two skilled interventional cardiologists, and in case of their discrepant opinions, the decision will be made on the basis of the third cardiologist. The tests will be applicated during the hospitalisation, then read after 48 hours and 72 hours, and subsequently interpreted by the skilled dermatologist, during the hospital stay or afterwards.
