Filter by:A prospective, open label, multi-center, single arm, observational study designed to evaluate the acute safety and device performance of the Sapphire 3 0.85, 1.0 and 1.25mm diameter coronary dilatation catheter in predilatation of Chronic Total Occlusion (CTO) lesions during percutaneous coronary intervention. One hundred seventy (170) subjects will be enrolled with a target of one hundred fifty-three (153) evaluable subjects by the angiographic core laboratory at up to 15 clinical sites with the Sapphire 3 0.85, 1.0 and 1.25mm diameter PTCA dilatation catheter to pre-dilate CTO lesions in coronary arteries during their index procedure. All subjects will be screened according to the protocol inclusion and exclusion criteria and will be followed through study completion, which is defined as 24-hours post-procedure or hospital discharge, whichever comes first.
The purpose of this study is to compare and assess efficacy and safety between the study device "TS-RF system consisting of a electrosurgical system, general-purpose (TS-RF Generator) and a electrosurgical system electrode, hand-controlled, general-purpose, single-use (TS-RF Needle)" and the control device "needle, puncture, single-use (BRK Transseptal needle)", both of which are used for the transseptal puncture performed to enable left atrial access for the treatment of symptomatic arrhythmia and mitral stenosis and then to demonstrate that the study device is non-inferior to the control device.
Despite significant clinical benefits and recommendations of clinical practice guidelines to refer patients for exercise and physical activity counselling in the capacity of cardiac rehabilitation (CR), CR is largely underutilised and not implemented effectively. Studies have reported that the reasons for the low implementation of CR are multifactorial at the healthcare system, physician and patient levels. Therefore, the aim of this study was to investigate the knowledge, attitudes and practical applications of paediatric cardiologists regarding cardiac rehabilitation and specifically exercise and physical activity in children with congenital heart disease (CHD).
Obesity is associated with type 2 diabetes (T2D) and cardiovascular disease (CVD). Metabolic and bariatric surgery (MBS) has in several randomized controlled trials (RCT) been shown to be superior to best medical therapy in the treatment of T2D. In the area of CVD, RCT after MBS are lacking. It was recently demonstrated in a cohort study that MBS in patients with severe obesity and a previous myocardial infarction (MI) was associated with a 50% reduction in the risk of death and new MI. The aim of this proposal is to confirm this in a nationwide RCT. Using the nationwide SWEDEHEART database patients with severe obesity and a previous MI will be identified. They will be contacted and offered participation. After informed consent the patients will be randomized to MBS or optimized care (including visit with a cardiologist and optimization of secondary preventive measures and referral to dietician/physiotherapist). The primary outcome measure is a major cardiovascular adverse event (MACE). Secondary outcome measures include mortality, new MI, stroke, heart failure and atrial fibrillation. Tertiary outcome measures include health related quality of life and surgical complications. Patients will be followed in the nationwide metabolic surgery register SOReg, the national inpatient register, national cause of death register, the Swedish prescribed drug register, and the Swedish population register. If positive results these can be included in guidelines for MBS.
The INTELICE trial is a prospective, multicenter, 1:1 randomized controlled non-inferiority study. It aims to compare a novel intracardiac echography (ICE) catheter and combined ultrasound system with existing commercial ones. The evaluation will be conducted on patients undergoing planned intracardiac interventional process.
This prospective, randomized controlled study is aimed to figure out suitable transfusion threshold in patients undergoing cardiac valve surgery under cardiopulmonary bypass(CPB). Patients are randomly assigned to restrictive and liberal transfusion group and receive blood transfusion during and after surgery. Compare primary and secondary outcomes of two groups.
The purpose of this study is to gain a better understanding of the association between brain changes and cognitive deficits in coronary heart disease (CHD) patients undergoing coronary artery bypass grafting (CABG) and whether a low-cost thiamine intervention can be used to reduce post-CABG cognitive issues in CHD subjects.
This observational study aims to learn about the preliminary exploration of 99mTc-FAPI imaging in heart diseases and its potential application. Participant involves patients with myocarditis, pulmonary hypertension, arrhythmia, myocardial infarction, dilated cardiomyopathy, and cardiac tumors, health conditions may also studied as control. The main questions it aims to answer are 1, radionuclide 99mTc labeled fibroblast-activated protein inhibitors (99mTc-FAPI) imaging in the use of cardiac diseases and its limitations. 2, the performance in subjects with different control of hypertension to evaluate myocardial injury and fibrosis for providing a molecular biological basis for the study of diseases and mechanisms. Participants will undergo 99mTc-FAPI imaging by Single-photon emission computed tomography (SPECT) and record their cardiac disease characterization and treatment.
There are many barriers to heart-healthy lifestyles in pediatric patients with acquired and congenital heart disease. Investigators want to further understand how participants heart and skeletal muscles work together during exercise and evaluate the impact on cardiac function. To do this, the investigators will use magnetic resonance imaging (MRI) to scan the heart and skeletal muscles during exercises to assess blood flow, oxygenation and function.
Delineate and evaluate the role of echocardiography in children with congenital heart disease undergoing cardiac catheterization in the pediatric cardiology unit of Assiut university hospitals. 1. To improve diagnostic accuracy by creating a systematic approach for image acquisition and interpretation across different procedural timepoints. 2. To promote consistent hemodynamic evaluations to reliably assess cardiac function and blood flow. 3. To enable optimized procedural planning and intraprocedural guidance via comprehensive delineation of anatomy and pathophysiology. 4. To facilitate standardized longitudinal monitoring after interventions to evaluate outcomes and detect complications.
