Filter by:Objective to investigate the safety and effectiveness of Echocardiography-guided radiofrequency ablation in patients with Hypertrophic obstructive Cardiomyopathy (HOCM). Percutaneous intramyocardial septal radiofrequency ablation (Liwen Procedure) is a safe and effective treatment approach for Hypertrophic obstructive Cardiomyopathy and results in sustained improvement in exercise capacity, persistent in reducing Left Ventricle Outflow Tract (LVOT) gradient, and sustained improvement in cardiac function. In patients with disabling symptoms caused by Hypertrophic obstructive Cardiomyopathy (HOCM),Echocardiography-guided radiofrequency ablation could be a less invasive treatment option. Percutaneous intramyocardial septal radiofrequency ablation (Liwen Procedure) is a new method for the diagnosis or treatment of heart disease by using a special diagnosis and treatment device to the heart target area under the guidance of image technology. The method breaks through the worldwide problem of the minimally invasive diagnosis and treatment of the myocardium on the beating heart, so as to avoid the X-ray radiation and contrast agent damage . As a new pathway of cardiac disease intervention, Liwen Procedure can be used in congenital heart disease, myocardial biopsies, drug injection, cell implantation and instrument implantation in addition to Hypertrophic Cardiomyopathy and cardiac tumors. It has important clinical value and broad application prospect. In this study, Liwen RF radiofrequency ablation system was used to treat HOCM , and evaluate its safety and effectiveness , in order to provide a new medical device for Liwen Procedure of HOCM.
This is a randomized, double-blind, placebo-controlled, multi-center study in the United States (U.S.) that will evaluate the effect of mavacamten treatment on reducing the number of septal reduction therapy (SRT) procedures performed in subjects with symptomatic obstructive hypertrophic cardiomyopathy (oHCM [also known as HOCM]) who are eligible for SRT based on ACCF/AHA 2011 and/or ESC 2014 guidelines.
COVID-19 is associated with complications including ARDS and myocardial injury, which informs prognosis and patient outcome. The laboratory plans to perform immunophenotyping of peripheral T-cells in patients with COVID-19 and complications (ARDS, ITU admission, myocardial injury) and map this against clinical patient outcomes. The aim is to determine if there is a specific T-cell immunophenotype associated with COVID-19 and/or complications, which can be used to inform prognosis and potential therapies.
The present study introduces a novel approach to coronary revascularization through the use of a short term minimally-invasive left ventricular assist device (LVAD) to minimize myocardial injury and eliminate low output state during the perioperative period
Prospective, randomized, open-label, international, multi-center clinical study to evaluate the safety and efficacy of the AccuCinch Ventricular Restoration System in patients with heart failure and reduced ejection fraction (HFrEF).
Hypertrophic Obstructive cardiomyopathy (HOCM) is the most common genetic cardiomyopathy, heterogeneous in phenotype and clinical course. The genotype-phenotype relationship and associated molecular mechanisms are still incompletely understood. In the HOCM milieu, increased energy cost of force production, impairing performance and mitochondrial function, may be associated to patients' genotype and/or phenotype
The purpose of this study is to optimize the complex treatment of chronic heart failure of non-ischemic etiology by supplementing umbilical cord mesenchymal stem cells to the standard drug therapy.
The goals of this study are as follows: 1. To rigorously establish and characterize heterogeneity in the pathophysiology of Takotsubo Syndrome (TS). 2. To rigorously test the contribution of TS triggering events and mental stress responsiveness to 1-year prognosis after TS event.
Background and study aim: Heart diseases are among the most common causes of death worldwide. A large proportion of deaths are caused by heart attacks (myocardial infarction), where blood flow to the heart is reduced resulting in damage to the heart muscle. If the arteries supplying blood to the heart start to become blocked, Coronary Artery Bypass Grafting (CABG) surgery is a treatment to replace the blocked sections of artery can reduce angina (chest pain). However, CABG surgery has complications, including an increased risk of heart attack. Vitamin D deficiency is thought to be linked to poorer recovery from heart attack and CABG surgery. This study aims to investigate if vitamin D supplementation can reduce injury to the heart following CABG surgery. Who can participate? Adults with vitamin D deficiency undergoing CABG What does the study involve? Participants are randomly allocated to one of two groups. Those in the first group receive vitamin D at 3 doses per day for 3 days before surgery. The second group will receive a dummy pill (placebo). Both groups will have standard CABG surgery. What are the possible benefits and risks of participating? Those in the vitamin D group might benefit from its effects. Vitamin D has few side effects, especially when taken for only a few days. Where is the study run from? Shahid Modarres Hospital (Iran) When is the study starting and how long is it expected to run for? September 2017 to January 2019 Who is funding the study? Deputy of Research of Shahid Beheshti School of Medicine Who is the main contact? Dr Erfan Tasdighi erfan.tasdighi@gmail.com
The aim of the study is to analyze cardiac biomarkers, electrocardiograms and cardio-pulmonary exercise test (CPET) results in children with cardiomyopathies.
