Filter by:The Stereotaxis Niobe® II Magnetic Navigation System (MNS) is designed to direct and digitally control catheter and guidewire based therapeutic and diagnostic devices along complex trajectories within the heart and coronary vasculature. Navigation using vectors acquired from the CT Co-registration feature of Navigant™ provides clinical benefits for percutaneous coronary intervention (PCI) by decreasing the amount of contrast used during complex PCI procedures.
The purpose of this study is to see whether apadenoson is as effective as adenosine when used as a pharmacological stress agent in myocardial SPECT-Imaging to detect defects in the supply of blood to the heart muscle (myocardial perfusion defects). The study will also look at whether apadenoson is better tolerated than adenosine when used in SPECT-MPI.
Patients enrolled will need treated with an IVUS- VH (intravascular ultrasound-derived virtual histology) which is an arterial stent procedure, that involves threading a tiny wire into the artery, followed by a balloon, a stent, or other device to treat a blocked artery, and often (though not always), a special ultrasound catheter to take pictures of the inside of the artery. Participants in the study, will have an additional procedure performed: a tiny tube will be advanced into the heart artery to collect a blood sample for research purposes, and a blood sample will be collected from the femoral (thigh) artery through the tube that will be placed there as a standard part of having this procedure. The blood that is collected will be analyzed for markers of inflammation or irritation in the blood (c-reactive protein, myeloperoxidase, Monocyte chemotactic protein-1), as well and a gene called Matrix Metallopeptidase 3, which is believe to influence the progression of plaque on the walls of arteries and the progression of coronary artery disease. .
This research study plans to evaluate the use of atorvastatin in patients with coronary artery disease given immediately before PCI and whether it will decrease the amount of heart damage after PCI.
The primary objective of Infinnium-Core™ Registry is to assess the safety and efficacy of the Infinnium-Core™ Paclitaxel Eluting Coronary Stent System in de novo Coronary Lesions.
The purpose of ST Detect study is to evaluate whether naturally occurring spontaneous coronary events and exercise induced cardiac ischemia, give rise to detectable changes on intracardiac electrogram (EGM) signals in patients that are indicated for an Implantable Cardioverter Defibrillator (ICD) who have coronary artery disease.
The objective of Series III Run-In Trial is to compare the performance and efficacy of the Supralimus® sirolimus-eluting stent with the Xience V™ everolimus-eluting stent with respect to in-stent luminal late loss at 9 months as assessed by off-line QCA. Ninety percent power to reject the null hypothesis that the Supralimus® stent is inferior to Xience V™ in favor of the alternative hypothesis that the Supralimus® stent is not inferior to Xience V™.
Assess the impact of lesion preparation using the AngioSculpt balloon in the treatment of bifurcation lesions in native coronary arteries.
The purpose of this study is to evaluate the extent of the mobilization of endothelial progenitor cells induced by low versus high dose atorvastatin after 4 weeks of treatment, in patients treated with anti-CD 34 antibodies coated stent.
To determine the efficacy of prasugrel versus clopidogrel for the reduction of adverse cardiovascular outcomes in patients with high platelet reactivity on clopidogrel after successful implantation of coronary drug-eluting stents. To determine the adverse event profile of prasugrel in patients with high platelet reactivity on clopidogrel after implantation of coronary drug-eluting stents. To determine the effect of prasugrel on inhibition of platelet activation in patients with high platelet reactivity on clopidogrel.
