Filter by:In study-1, the purpose of this study is to compare the long-term outcome of provisional stenting between EES and SES deployment. In study-2, it is to prove the following hypothesis " Asymmetrical expansion in the bifurcation lesion leads to frequent inhomogeneous intimal growth on the strut and thrombus attachment."
To evaluate the safety of a new bioresorbable (non-permanent) stent platform in native coronary arteries.
This randomized, controlled, diagnostic, multicenter trial will compare two diagnostic imaging pathways--coronary computed tomography angiography (CCTA) and single photon emission tomography (SPECT) myocardial perfusion imaging (MPI)--to determine the incidence of major adverse coronary events (MACE), defined as myocardial infarction (MI) or cardiac-related death, and cross-over to revascularization. CCTA may be used to direct patients with symptoms of stable angina or angina equivalent to optimal medical therapy (OMT). The use of CCTA as a diagnostic tool for angina symptoms will be associated with no increase in MACE or revascularization, decreased cost, reduced risks (e.g., less radiation exposure), additional insights into alternate explanations of chest pain, and increased cost-effectiveness in comparison with use of SPECT MPI/invasive coronary angiography (ICA).
Title Prospective, single-arm, multi-centre, observational registry to further validate safety and efficacy of the Nobori® DES in real-world patients. Objective Primary objective The primary objective of e-NOBORI registry is to further validate the safety and efficacy of Nobori® DES system in unselected patients representing everyday clinical practice. Primary Endpoint: Freedom from Target Lesion Failure (TLF) defined as a composite of cardiac death, target vessel related myocardial infarction (MI) and clinically driven target lesion revascularization (TLR) at 1 year
This study is being conducted to determine if smoking will influence the platelet aggregation inhibition ability of clopidogrel and prasugrel. It will also determine if smoking has any effect on the plasma concentrations of the active metabolite of prasugrel and the active and inactive metabolites of clopidogrel. The primary hypothesis is that smoking status will influence the antiplatelet effects and active metabolite concentrations of clopidogrel but will have no impact on prasugrel's antiplatelet effects or active metabolite concentrations.
The objective of this pilot study is to compare the PFS-eluting stent (ISAR Rapa G1) with the PPS-eluting stent (Cypher®) regarding uncovered stent strut segments at 5 years.
Each year in the United States, 300,000 people suffer from a Cardiac Arrest (CA), and of them, there is a 90% mortality rate. Out-of-Hospital arrests, in particular, have a 1-5% survival to hospital discharge. High quality CPR is crucial to lowering the mortality rate and increasing survival, yet only 15-30% of out-of-hospital CA victims receive bystander CPR. Studies have shown that prompt administration of CPR dramatically improves outcomes. In a recent study from Switzerland, lay bystander CPR doubled the survival rate at one month. Our study will look to train family members of at-risk cardiac patients in the skills of CPR through the American Heart Association's (AHA) CPR Anytime Friends and Family Personal Learning Program (CPR Anytime) to see if these family members are able to learn and perform quality CPR in the event that their family member should suffer a cardiac arrest.
Biventricular pacing is a validated treatment for patients suffering from heart failure resistant to medical treatment. However, up to 30% of the patients are non responsive to this strategy using the coronary sinus approach to pace the Left Ventricle (LV). It has been demonstrated that the magnitude of the improvement was highly dependant on the LV pacing site. The coronary sinus approach rarely offers more than 1 or 2 potential pacing sites. Resynchronisation using a transeptal approach to pace the left ventricle on the cardiology has been shown feasible on small series. We therefore would like to compare these two approached in a randomised prospective study to confirm the hypotheses that endocardial LV pacing by offering multiple choices for the pacing sites reduces the number of non responders and is associated with greater hemodynamic benefit when compared to the conventional coronary sinus approach.
The Tryton Side Branch Stent System has been designed to address the procedural difficulty surrounding treatment of bifurcation lesions and to ensure patency of the side branch with similar performance capabilities (e.g., tracking, radiopacity, coverage and radial strength) that are currently available with conventional coronary stents designed for straight (non bifurcation) lesions. The Tryton Side Branch Stent is intended to treat and maintain patency in the side branch/carina by providing better ostial side branch conformability and is intended for use in conjunction with currently approved balloon-expandable drug-eluding stents for treatment of the main branch.
The goal of this study is to assess the long-term efficacy and safety of Firebird2 Cobalt-Chromium（CoCr）-alloyed sirolimus-eluting stent in treatment of complex lesions in diabetes.
