Filter by:This study will evaluate the relationship of Fractional Flow Reserve (FFR) and Minimal Lumen Area (MLA) by IntraVascular UltraSound (IVUS) by comparing the results of the both tests which is done as a part of the cardiac catheterization.
The purpose of this study is to document the safety and overall clinical performance of the Endeavor Resolute Zotarolimus-Eluting Coronary Stent System in a patient population with long lesion(s) and/or dual vessels requiring stent implantation.
XIENCE V USA is a prospective, multi-center, multi-cohort post-approval study. The objectives of this study are - To evaluate XIENCE V EECSS continued safety and effectiveness during commercial use in real world settings, and - To support the Food and Drug Administration (FDA) dual antiplatelet therapy (DAPT) initiative. This initiative is designed to evaluate the composite of all death, myocardial infarction (MI) and stroke (MACCE) and the survival of patients that are free from Academic Research Consortium (ARC) definite or probable stent thrombosis (ST) and that have been treated with drug eluting stents (DES) and extended dual antiplatelet therapy.
Narrowing of coronary arteries interferes with blood flow and can cause chest pain. Cardiologists sometimes quantify the extent of the narrowing by measuring the fractional flow reserve (the ratio of the pressure in the aorta to the pressure downstream of the narrowing under conditions of maximal flow). We propose a new technique based on principles of wave intensity analysis (WIA) to better assess coronary stenosis and the significance of the narrowing without the need for administration of vasodilator agents such as adenosine. This would simplify assessment and improve our ability to advise patients whether stent treatment will help their symptoms.
The purpose of this study is to evaluate the safety and effectiveness of the AVJ-09-385 Small Vessel Everolimus Eluting Coronary Stent System (EECSS) (2.25 mm diameter stent) in treatment of subjects with ischemic heart disease caused by de novo lesions.

The 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.
The TWENTE Study is a single center prospective single-blinded randomized study. Randomization will involve the type of Drug-Eluting Stent (DES) used in study population. Patients will be blinded to the type of DES they will receive. The general practitioner of the patient will be requested not to disclose this information to the patient. Analysts who perform the data analyses will be blinded to the type DES used as well.
The ABSORB EXTEND trial is to continue the assessment of the safety and performance of the ABSORB Bioresorbable Vascular Scaffold (BVS) System ABSORB BVS is currently in development at Abbott Vascular.
The investigators aim at analyzing the diagnostic accuracy of 320-row CT for coronary stents.
