BACKGROUND Improved motion-sensitized driven-equilibrium (iMSDE) preparations have been successfully used in carotid artery wall imaging to achieve blood suppression, but it causes notable signal loss, mostly due to inherent T2 decay, eddy current effects and B1 + inhomogeneity. In this study, we investigate the signal to noise ratio (SNR) and blood suppression performance of iMSDE using compos...

INTRODUCTION Event rates after percutaneous coronary interventions (PCI) are higher in small than large coronary vessels but may vary between different drug-eluting stent (DES) types. AIM To assess the efficacy of two different DES in small vessel disease. MATERIAL AND METHODS Patients with small vessel PCI were randomised 1 : 1 to a first-generation paclitaxel- vs. a second-generation zota...

Methods Primary PCI was performed in 3,345 (92.9%) of 3,602 patients in the HORIZONS-AMI (Harmonizing Outcomes With Revascularization and Stents in Acute Myocardial Infarction) trial; in-hospital protocol-defined non–coronary artery bypass graft–related major bleeding developed in 231 (6.9%). We examined medication use at discharge, mortality, and major adverse cardiovascular events (composite ...

The epicardial coronary arteries experience significant torsion in the axial direction due to changes in the shape of the heart during the cardiac cycle. The objective of this study was to determine the torsional mechanical properties of the coronary arteries under various circumferential and longitudinal loadings. The coronary artery was treated as a two-layer composite vessel consisting of in...

A novel, goal function-based formulation for the growth dynamics of arteries is introduced and used for investigating the development of growth instability in blood vessels. Such instabilities would lead to abnormal growth of the vessel, reminiscent of an aneurysm. The blood vessel is modeled as a thin-walled cylindrical tube, and the constituents that form the vessel wall are assumed to deform...

Background—The optimal duration of dual antiplatelet therapy (DAPT) after implantation of drug-eluting coronary stents remains undetermined. We aimed to test whether 6-month DAPT would be noninferior to 12-month DAPT after implantation of drug-eluting stents. Methods and Results—We randomly assigned 1443 patients undergoing implantation of drug-eluting stents to receive 6-or 12-month DAPT (in a...

background: autoregulation of blood flow is a marvelous phenomenon balanc- ing blood supply and tissue demand. although many chemically-based explanations for this phenomenon have been proposed and some of them are commonly used today, biomechanical aspects of this phenomenon was neglected. the biomechanical aspect provides insights to us to model vessel diameter changes more precisely and comp...

Abstract The composite over-wrapped pressure vessel (COPV), which were made by ultra-thin metal liner and high strength carbon fiber reinforced plastic (CFRP), has performance factor (PV/W). COPV widely used in electric propulsion system (EPS) of space system. ANSI/AIAA S-081-2000 is a general standard for aerospace field at home abroad, it specified the design elements, references, specificati...
