Filter by:The aim of the study is to compare different devices available to measure fractional flow reserve (FFR) in coronary arteries.
A prospective, open label, multi-center, single arm, observational study designed to evaluate the acute safety and device procedural success of the Sapphire II PRO 1.0 and 1.25 mm PTCA dilatation catheters in subjects with stenotic coronary arteries or bypass grafts during percutaneous coronary intervention. Sixty (60) subjects will be treated at up to 5 U.S. sites with the Sapphire II PRO diameters 1.0 and 1.25 mm PTCA dilatation catheters to pre-dilate coronary arteries or bypass grafts during their index procedure. All subjects will be screened according to the protocol inclusion and exclusion criteria and will be followed through hospital discharge.
Acute myocardial infarction (AMI) pose a pool clinical outcome to men and women whom treatment was delayed. However, reperfusion time was limited in previous studies. To evaluate the system delay and clinical outcomes among Chinese patients with AMI, consecutive inpatient case prospectively collected from 1999 to 2016. Basic data and innovative evidence will accelerate evidence-based clinical practice and policy making, and improve AMI patients outcomes finally.
This is a clinical trial to test the clinical feasibility and safety of a novel CMR protocol, combined with a specific breathing maneuver to identify myocardial regions exposed to severe coronary artery stenosis.
There is growing evidence that central blood pressure is a better predictor of hypertensive end-organ damage and cardiovascular outcome than routine brachial readings. The investigators aimed to evaluate the accuracy of a novel device for the non-invasive determination of central blood pressure based on automated oscillometric radial pulse wave analysis.
Clinical trial with an "European Community marked" medical device in patients with ischemic heart disease and clinical indication of coronary revascularization with drug-eluting stent. Clinical follow-up will be done according to this way: first month telephone or face-to-face interview and at 6 ± 1 month an Angiography follow up + OCT (optical coherence tomography) A randomized clinical trial to compare the efficacy of Angiolite Stent versus a second-generation drug-eluting stent such as Xience stent.(non-inferiority design)
The study aims to: 1. Characterize coronary artery disease (CAD) using CT Angiography (CTA) and scaling power law in 100 patients with obesity 2. Characterize cardiac remodeling using curvedness-based MRI in 100 patients with obesity 3. Compare the differences of cardiac and vascular remodeling in patients with metabolic syndrome and those without

This registry is a clinical post-market evaluation of the Genoss DES in subjects requiring coronary revascularization with Drug Eluting Stents (DES).
Invasive coronary angiography is currently considered gold standard in the assessment of coronary artery disease although the method has limitations. Most importantly invasive angiography only depicts coronary anatomy without determining its physiological significance i.e the likelihood that the stenosis impedes oxygen delivery to the heart muscle. Fractional flow reserve (FFR) is a catheterization technique for assessing the physiological significance of a coronary artery lesion during invasive coronary angiography. Coronary computed tomographic angiography (CCTA) is a noninvasive imaging test that has become an alternative route to diagnosis for patients with suspected coronary artery disease. Computational fluid dynamics combined with anatomical models based on CCTA scans allows determination of coronary flow and pressure, and has emerged as a promising diagnostic modality called CT-FFR. In this Project New Mathematical algorithms are developed for computation of CT-FFR. The main objective of this study is to determine the diagnostic accuracy of CT-FFR values obtained by the new method compared with invasive coronary angiography with fractional flow reserve and state-of-the-art dobutamin stress echocardiography.
