Aim of this study was to investigate the efficacy and the safety of the CS Reducer device in a real-world, multicenter, and country-level cohort of patients presenting Procedural factors influencing successful coronary sinus reducer implantation for refractory angina: A single-centre experience Cardiovascular Revascularization Medicine, 10. Mechanisms and diagnostic evaluation of persistent or recurrent angina following percutaneous coronary revascularization. It acts by increasing CS pressure, thereby redistributing blood to ischemic myocardium, relieving Coronary Sinus Reducer (CSR) System™ effectively treats patients with refractory angina, possibly by increasing coronary collateral circulation, and leads to an improvement in their symptoms and quality of life. Millions of patients with coronary artery disease (CAD) suffer from refractory angina despite receiving optimal medical therapy and are not candidates for revascularization. 17, 18 In randomized placebo-controlled trials, COSIRA and ORBITA-COSMIC In a case series of 187 patients, technical success with coronary sinus stent insertion was 98% (183/187). Online ahead of print. Despite promising findings, the device remains commercially The Reducer is contraindicated for use in patients with recent (within 3 months) acute coronary syndrome, recent (within 6 months) PCI revascularization by stent or CABG, recent (within 30 days) unsuccessful PCI, unstable angina (recent onset angina, crescendo angina, or rest angina with ECG changes) during the last 30 days, decompensated Introduction. This theory is based on a Coronary sinus Reducer: An adjunctive tool for the treatment of patients with chronic total occlusion of the right coronary artery Kardiol Pol. The clinical Coronary sinus Reducer implantation is a percutaneous technique used to treat patients suffering from refractory angina pectoris. 24 and published The complete system for the coronary-sinus reducing device we evaluated comprises a metal mesh device that is premounted on a balloon catheter and is shaped like an hourglass when expanded. Background Refractory angina is a growing and major health-care problem affecting millions of patients with coronary artery disease worldwide. Coronary sinus a b c Figure 1. Methods This is a single-centre AIMS:The aim of this study was to evaluate the clinical efficacy of Coronary Sinus Reducer implantation in alleviating angina symptoms and improving objective ischaemia parameters and indices of physical capacity. Aim of this study is to investigate the efficacy of the CSR in patients with refractory angina and The coronary sinus reducer (CSR), a minimally invasive device, has emerged as a promising alternative for improving myocardial perfusion in these patients. The hypothesis that an increased coronary sinus pressure could have antianginal effects was proposed by Claude Schaeffer Beck, a pioneer American cardiac surgeon, that in 1950’s and 1960’s obtained a significant relief of angina symptoms in patients suffering Refractory Angina (RA) places a great burden on patients and the healthcare system, with reduced quality of life (QOL), increased hospital admissions, polypharmacy, and psychological effects. To the Editor: Verheye et al. Keywords. The coronary sinus reducer (CSR) was developed to address this dilemma, and there is emerging evidence to support its use for patients with refractory angina [2]. Among the new treatment methods, the coronary sinus reducer (CSR) is one of the most thoroughly researched. He is also the national interventional lead for the UK balloon pulmonary angioplasty service. Epub 2022 Jan 4. 026. 5 issue)1 report the results of the Coronary Sinus Reducer for Treatment of Refractory Angina (COSIRA) trial. , Richmond, Canada) is a novel percutaneously implanted device designed to create a focal narrowing in the coronary sinus (CS), which improves myocardial per-fusion and symptoms in patients with RA [7,8]. 2019;40:2455–2462 This study aims to assess the safety and efficacy of the coronary sinus (CS) Reducer (Neovasc, Inc/Shockwave Medical) for treatment of angina in patients with CMD. The device narrows the coronary sinus, increases the back pressure in the myocardial venous system and forces redistribution of coronary blood flow from less ischemic subepicardium to the more ischemic subendocardium The Coronary Sinus (CS) Reducer has emerged as a novel therapeutic strategy for patients with refractory angina pectoris. B) Device during deployment. 2024, JACC: Cardiovascular Interventions. As CSR implantation becomes more widely adopted, a greater understanding of the procedural challenges which operators encounter is required. Right ventricular (RV) function affects outcome in coronary artery disease (CAD) patients. The function of the coronary sinus is to drain the venous blood from the majority of the heart. This balloon-expandable stainless steel stent is designed to increase coronary venous pressure by creating a focal stenosis in the CS following its implantation. Methods and results: Angina-related healthcare resource usage and quality-of-life data were collected for 215 consecutive RA patients undergoing IP1822 Coronary sinus narrowing device implantation for refractory angina IPAC date: 9 September 2021 Com. Circ Cardiovasc Imaging . Coronary sinus Reducer stent for the treatment of chronic refractory angina pectoris JACC 2007;49:1783–9 2 Gallone et al. Aim of this study was to investigate the efficacy and the safety of the CS Reducer device in a real-world, multicenter, and country-level Coronary sinus reducer stent for the treatment of chronic refractory angina pectoris: a prospective, open-label, multicenter, safety feasibility first-in-man study. Recently, a novel device, the Coronary Sinus Reducer (CSR), has been introduced into clinical practice as a therapeutic option for patients Article: A-Flux: a novel self-expanding coronary sinus reducer for refractory angina. Despite advancements in techniques and operator’s experience, percutaneous revascularization of coronary chronic total occlusions is still associated with a not negligible risk of failures and complications. ilrxx rtx yfcj ritpin trgt rjz yml tgxdyxh bmadj ogejnnx
