The aim of this prospective randomized study was to assess the efficacy of ablation of the ganglionated plexi localized in the epicardial fat pads for preventing recurrences of atrial tachyarrhythmia in patients with paroxysmal atrial fibrillation undergoing coronary artery bypass grafting.
The aim of this prospective randomized double-blind study was to compare the efficacy of new pharmaceutical composition containing botulinum toxin injection in epicardial fat pads for preventing recurrences of atrial tachyarrhythmia in patients with paroxysmal atrial fibrillation undergoing coronary artery bypass grafting.
The "Cliniques Universitaires Saint Luc" are one of the high specialized center in valvular heart diseases and valvular heart surgery. Aortic stenosis, mitral and aortic regurgitation are the three valve pathology that are mainly frequent and studied. International guidelines in the management of valvular heart diseases are based on few limited old studies, mainly retrospective. And, a matter of concern is staying, about the timing of surgery for asymptomatic patients. A prospective registry will help us to better understand the pathologies and try to better define guidelines criteria for surgery.
The objective of this study is to use of STIC technology to assist the traditional echocardiography to diagnose the fetal congenital heart disease accurately and then to provide a basis for prenatal counseling.
Coronary heart disease is still the major cause of death in China. Chinese medicine plays more and more important role in CHD prevention and treatment. Phlegm and blood stasis are its major pathological basis. Based on that, the investigator aims to evaluate the evolutionary process of CHD phlegm-blood stasis syndrome by large samples, multi-centre, cross-section observation combining with longitudinal tracking on-site survey method so as to guide the clinical treatment of CHD.
evaluate the safety of preoperative aspirin therapy when performing bypass surgery in conditions of artificial blood circulation
This is a multi-centre, open, randomised study in patients treated for ischemic heart disease in Linköping, Norrköping and Jönköping hospitals. One thousand two hundred patients who are treated at the cardiac rehabilitation units will be consecutively recruited during three years. The patients will be randomised 1:1 to be given advice on a 1) Mediterranean diet with an energy content (E%) from carbohydrates between 25-30% or to 2) a traditional low-fat diet with 45-60 E% from carbohydrates. All eligible patients will be asked if they want to participate and provided with written information about the study when they are discharged from the hospital after treatment for ischemic heart disease. The decision to participate or not will be given at the following outpatient treatment at the cardiac rehabilitation unit. When the signed informed consent to participate in the study has been provided, the patient will be randomised to advice of either of the two dietary regimes.
The investigators will conduct a randomized controlled trial that aims to compare the incidence of contrast-induced nephropathy between transradial- and transfemoral-access cardiac catheterization.
Rationale: Adult patients with congenital heart disease (CHD) with atrial tachyarrhythmias need to be anticoagulated. It is not known whether non-vitamin K antagonist oral anticoagulants (NOAC) in this patient group are efficient and safe. Aim: The purpose of the NOTE registry is to evaluate the efficacy and safety of NOACs for thromboembolic prevention in atrial tachyarrhythmias in adult patients with congenital heart disease (CHD). Methods: In this multicenter prospective registry adult CHD patients with atrial tachyarrhythmias on NOACs (switch from VKA or new on anticoagulants) will be followed for a minimum of two years. Primary efficacy endpoints are defined as thromboembolism, i.e. the composite of ischemic stroke, systemic and pulmonary embolism and intracardiac thrombosis, and as the composite of stroke and systemic embolism. Primary safety endpoint is defined as major bleeding according to the ISTH criteria. Secondary endpoints include each thromboembolic or bleeding event analysed separately, all-cause mortality, therapy adherence, quality of life, risk assessment of stroke and evaluation of natural history of atrial tachyarrhythmia in adult CHD patients. Primary endpoint assessment will be performed with a per protocol analysis, and demonstrated as Kaplan Meyer estimates of event free survival and event rates per year.
