Filter by:To establish the safety and efficacy of the commercially approved XIENCE Family Stent System (inclusive of XIENCE PRIME, XIENCE V, XIENCE Xpedition and XIENCE PRO [for use outside the United States [OUS] only]) in subjects with unprotected left main coronary artery disease by comparing to coronary artery bypass graft surgery.
The purpose of this Clinical Evaluation is the continued assessment of the XIENCE Everolimus Eluting Coronary Stent System (XIENCE V® and XIENCE PRIME™ EECSS) with the primary focus on clinical outcomes in the treatment of female patients with de novo coronary artery lesions, and the characterization of the female population undergoing stent implantation with a XIENCE stent.
This is a prospective, randomized, active-controlled, open label, parallel two-arm, multi-center, post-approval study descriptively comparing the XIENCE V EECSS to the CYPHER SELECT PLUS Sirolimus-Eluting Coronary Stent System (SECSS) ("CYPHER SELECT PLUS") during commercial use in China.
The Zenith® TX2® Low Profile TAA Endovascular Graft study is a clinical trial approved by US FDA to evaluate the safety and effectiveness of the Zenith® TX2® Low Profile TAA Endovascular Graft indicated for the treatment of patients with aneurysms/ulcers of the descending thoracic aorta having vessel structure suitable for repair.
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.
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.

Impairment of the heart's pumping capacity (heart failure) remains a major clinical problem with a poor prognosis and the search for novel treatments remains an important area of research. Urocortins are proteins that appear to increase blood flow and heart pumping activity. There has been particular interest in the role of Urocortins 2 & 3 (subtypes of Urocortins) in heart failure. In this study, we will examine the effects and mechanisms of Urocortins 2 & 3 on forearm blood flow and release of natural blood clot dissolving factors in the forearm circulation of healthy volunteers. In particular, we look at the endothelial mechanisms of vasodilatation of Urocortin 2 and 3. In this study, we will look at the role of the lining of the blood vessel (endothelium) in response to urocortin types 2 and 3. We hypothesise that urocortins 2 & 3 act via the endothelium to cause dilatation of the blood vessels and release of tissue-plasminogen activating factor (blood clot dissolving factor). We also hypothesise that urocortins have a role in maintaining the normal baseline level of blood flow in forearm arteries. In addition to the above, we will also look at the effect of temporarily blocking the effect of urocortins, using a specially designed blocker drug (Astressin 2B). Utilising the well-established technique of 'forearm venous occlusion plethysmography', we will be able to focus on the local effects of urocortins on arterial blood flow in forearm vessels, without affecting this system in the body as a whole.

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.
