Filter by:The BioNIR Ridaforolimus Eluting Coronary Stent System is a single use device/drug combination product comprising: - Stent - mounted Cobalt Chromium (CoCr) alloy based stent - Delivery System - Rapid Exchange (RX) Coronary System - Polymer matrix coating - Poly n-butyl methacrylate (PBMA) and polymer coating (CarboSil®) - Ridaforolimus drug - Chemical Abstracts Service (CAS) Registry Number: 572924-54-0 The product is indicated for improving coronary luminal diameter in patients with symptomatic heart disease due to lesions in vessels with reference diameters of 2.5mm to 4.25mm, including complex lesions.
The purpose of this study is to identify if circulating platelet cyclic adenosine monophosphate (cAMP) levels can be used as a biomarker of milrinone efficacy in children following cardiac surgery or undergoing heart transplant.
The heart is essentially a hydraulic pump which ensures adequate delivery of blood through generating pressure and forward flow of blood. The energy delivered by the heart is uncommonly measured clinically, and todays gold standard involves placing a plastic catheter into the lung arteries. The investigators have developed an ultrasound based approach to calculate this energy without the need for catheters through the heart. This novel approach is called ultrapower. Ultrapower involves the instantaneous multiplication of the cardiac output and the arterial blood pressure. The study aims to use the ultrasound based approach to investigate Cardiac Power in the coronary artery bypass graft population.
The study aims at the comparative examination of pre-, intra- and post-operative release profiles of inflammatory and vasoactive mediators in patients undergoing heart valve surgery under cardiopulmonary bypass (CPB) due to either infectious endocarditis or degenerative valvular heart disease. Specific attention will focus on the distinction between mediator release associated with infection and that resulting from CPB. Concomitantly identification and characterization of infectious pathogens in the circulation and in valvular samples will be carried out, together with the search for resistance-coding transcripts.
To investigate the efficacy and safety of using the novel Tyto device for remote physical examination by co-investigators as compared to a standard medical physical examination by physicians.
The guideline-recommended standard of care for patients who have experienced a heart attack, heart failure, or other coronary event or procedure is exercise-based cardiac rehabilitation (CR). Despite proven benefits, traditional CR is severely underutilized. Moreover, what is typically lacking from traditional CR programs is effective psychosocial risk management. This represents a critical gap in care given the well-documented psychosocial needs of this patient population.The objective of this feasibility study is to conduct a pilot randomized controlled trial (RCT) of Mindfulness-Based Stress Reduction (MBSR) versus usual care in CR-eligible cardiac patients. Randomization will be stratified within two strata based on participation in CR (yes/no) among CR-eligible patients. The primary goals of this pilot study are to: 1) obtain estimates of treatment effects and variability; 2) evaluate recruitment and retention strategies; and 3) examine the safety of the MBSR protocol in CR-eligible patients.
Ischemic reperfusion injury of cardiopulmonary bypass and postoperative renal dysfunction is a common problem which influence poor outcome in subjects undergoing valvular heart surgery. The incidence of postoperative renal dysfunction was reported as high as 7~8% in heart surgery using bypass, and is thought to be caused by ischemia/reperfusion injury. Remote ischemic postconditioning was also reported to be protective for ischemic/reperfusion injury in previous animal studies and stoke patients. Therefore, the investigators are trying to evaluate the clinical effect of remote ischemic postconditioning on postoperative renal dysfunction in subjects undergoing valvular heart surgery with bypass.
The purpose of the study is to examine previously examined patients with cyanotic congenital heart disease to assess how many of the patients have obtained additional blood clots since they were examined 8 years ago.
This project will examine the association between (cardio)vascular disease, blood supply to the brain, and cerebrovascular endothelial activation. Also, we will investigate the impact of exercise rehabilitation on brain vascularization, cerebrovascular endothelial function and blood flow control.
A study about accuracy of pulse oximeter with hypoxemic measurements (Blue sensor, Masimo, Irvine, CA, USA) in children with cyanotic congenital heart disease
