XIENCE V/PROMUS Everolimus-Eluting Stent System Post-marketing Surveillance Protocol for Japan
AnginaChronic Coronary Occlusion7 moreThe objectives of this post-marketing surveillance, conducted in Japan, is to know the frequency, type and degree of device malfunction, to assure the safety of the medical device, and to collect information on evaluation of the efficacy and safety.
EXecutive Registry: Evaluating XIENCE V® in a Multi Vessel Disease
Coronary DiseaseCoronary Artery Disease2 moreThe purpose of this two part study is the assessment of the performance of the XIENCE V® Everolimus Eluting Coronary Stent System (XIENCE V® EECSS) in the treatment of the specific setting of patients with Multi-Vessel Coronary Artery Disease (MVD).
Chronic Total Occlusion Registry
Coronary OcclusionCoronary Artery Stenosis1 moreThis study evaluated the long-term outcome of patients with chronic total occlusion treated with percutaneous coronary intervention, medical treatment or coronary artery bypass grafting.
Detection of Coronary Stenosis With Intravenous Microbubbles
Coronary StenosisCarotid Stenosis1 moreTo detect coronary artery disease by both coronary and carotid artery imaging and myocardial perfusion imaging using a new low mechanical index real time system.
Use of Magnetocardiography in Evaluation of Patients Going for Cardiac Catheterization
Acute Coronary SyndromeCoronary Artery Stenosis1 moreThis is a multicenter, prospective trial to measure the test performance characteristics of the Magnetocardiography (MCG) CardioFlux cardiac diagnostic system in detecting clinically significant coronary artery obstruction in patients with symptoms of suspected acute coronary syndrome or who present with a failed stress test with the intention of treat with cardiac catheterization.
IRIS-Firehawk® Cohort in the IRIS-DES Registry
Coronary StenosisCoronary DiseaseThe objective of this study is to evaluate effectiveness and safety of Firehawk® stent in the "real world" daily practice as compared with other drug-eluting stents.
Relationship Between Pressure and Flow Velocity on Coronary Physiology
Coronary StenosisSubjects are patients who are planned to do percutaneous coronary intervention for coronary stenosis in the left circumflex artery without other stenosis in the left ascending artery and the right coronary artery, or a patient with normal coronary artery. Immediately after coronary angiography or percutaneous coronary intervention, the investigators will evaluate for coronary hemodynamics by distribution of wave intensity which is calcurated by coronary pressure and flow velocity with Combowire in each coronary segment. Also, they will assess coronary morphology by View It in each coronary segment.
Contrast Volume Reduction During PCI With the Use of a New Assisting Software Package
Coronary StenosisCoronary OcclusionThe new software package is intended to assist the physician in imaging the coronaries during percutaneous coronary interventions. This study investigates the amount of contrast used during percutaneous coronary interventions with the aid of the new software package. The results of the study will be compared with control group data (before the new software package was installed or after it was removed) to define a possible contrast reduction.
Physiologic Assessment of Coronary Stenosis Following PCI
Coronary Artery DiseaseCoronary Stenosis4 moreThis is a pilot study designed to assess the relationship between iFR (instantaneous wave-free ratio) pullback and the distribution of coronary atheroma/stenoses as assessed by Quantitative Coronary Angiography (QCA) post angiographically successful PCI (Percutaneous Coronary Intervention).
Thrombin Generation Values and Percutaneous Coronary Intervention Results.
Coagulation DisorderIschemic Heart Disease1 moreCardiovascular diseases are the most common cause of death in the western world. Myocardial infarction pathogenesis usually involves the development of an atherosclerotic plaque and thrombus. Past research has shown a correlation between thrombin generation values and ischemic heart disease, however, to our knowledge no investigation has been done into the correlation of thrombin generation and cardiac catheterization results in ischemic heart disease patients. In the current research the investigator will investigate the correlation of thrombin generation values using calibrated automated thrombogram and cardiac catheterization results in active ischemic heart disease patients.
