Active clinical trials for "Coronary Stenosis"

The HYUMC registry is a two-center, real-world registry of percutaneous coronary intervention in patients with coronary artery disease. From January 2012, PCI-treated patients from Hanyang University Seoul Hospitals and Hanyang University Guri Hospitals were enrolled in this registry. The aim of this registry is to examine the long-term clinical outcomes and identify predictors of adverse outcomes following percutaneous coronary intervention conducted at academic hospitals.

This is a randomized, non-inferiority, crossover investigation comparing the Direct Wire Pacing (DWP) versus standard method to measure Fractional Flow Reserve (FFR) in subjects with FFR indications. All subjects requiring on a clinical basis a pressure wire assessment of coronary artery stenosis(es) will be eligible to take part in the study.

Coronary-related myocardial ischemia can result from obstructive epicardial stenosis or non-obstructive causes including coronary microcirculatory dysfunction and vasomotor disorders. This prospective study has been created in order to provide knowledge in the field of non-obstructive coronary artery disease.

The objective of this study is to evaluate safety and effectiveness of the SINOMED CBC coronary dilatation catheter during PCI in subjects with stenotic coronary arteries.

Multidisciplinary team-approach in order to offer personalized treatments represents the emerging mainstream in cardiovascular medicine. "Hybrid operative rooms" allow to offer selected heart-disease patients truly "tailored" operations. This study wants to evaluate the effectiveness and safety of Hybrid Procedures in cardiac patients in three subgroups of patients: Hybrid coronary revascularization strategy (coronary by-pass + PCI); Hybrid valve and coronary disease correction (combination of surgical valve replacement and PCI); Hybrid coronary and carotid artery disease treatment (combination of coronary by-pass and carotid stenting). The investigators hypothesize that morbidity might be reduced by 50% in hybrid procedures group as compared with predicted Society of Thoracic Surgery (STS) score.

This study aims to evaluate procedural and clinical outcomes of acute coronay syndrome (ACS) patients with aneurysmatic culprit right coronary artery (RCA).

The investigators aimed to identify the value of concordance between the diastolic hyperemia-free ratio (DFR) and fractional flow reserve (FFR) during pre-interventional and post-interventional period using a 0.014" COMET II Pressure Guidewire

The objective of this study is to evaluate effectiveness and safety of BIOFREEDOM™ FAMILY stent in the "real world" daily practice as compared with other drug-eluting stents.

This study evaluates effectiveness and safety of DESyne X2 in Routine Clinical Practice.

The objective of this randomized study was to compare outcomes of imaging-and physiology-guided state-of-the-art Percutaneous coronary intervention (PCI) to coronary artery bypass grafting (CABG) in patients with diabetes and multivessel coronary artery disease(CAD) with left anterior descending(LAD) involvement.
