NCT ID: NCT06137885 Recruiting - Heart Failure Clinical Trials

REgiStry-based Cardiovascular qUality improvEment Research

RESCUER
Start date: April 24, 2023
Phase:
Study type: Observational [Patient Registry]

The goal of this registry-based observational study is to establish a comprehensive management plan, which focus on medical therapy, cardiac rehabilitation and active post-market surveillance of medical devices, in patients with cardiovascular diseases (CVD). Patients with CVD mainly refers to four groups of patients:1) post-percutaneous coronary intervention (post-PCI) patients; 2) patients with heart failure (HF); 3) patients with cardiometabolic diseases (CMD); 4) patients with structural heart disease (SHD), and the detailed definition of each group can be found in "Eligibility" section. The main questions this study aims to answer are: - the effectiveness of exercise-based cardiac rehabilitation in improving cardiac function, reducing CVD recurrence and mortality, and promoting quality of life for patients with CVD; - the feasibility of registry-based active post-market surveillance of high-risk medical devices used in cardiovascular surgeries, such as PCI, heart valve replacement, and cardiac resynchronization therapy (CRT); - the utilization of multiomics datasets to identify and dissect cardiovascular heterogeneity in both healthy and diseased populations and to guide precision medicine in patients with CVD; - the analysis and evaluation of the prescription patterns and drug response in patients with CVD.

Stereotactic Ablative Radiotherapy for the Treatment of Refractory Ventricular Tachycardia

SABRE-VT
Start date: January 21, 2023
Phase: N/A
Study type: Interventional

Ventricular tachycardia (VT) is an abnormal rhythm arising from the bottom chambers (ventricles) of the heart. The hearts of most patients who develop VT have been previously damaged by a myocardial infarction (heart attack) or other heart muscle diseases (cardiomyopathies). The damage produces scar or fatty deposits that conduct electrical impulses slowly allowing VT to occur. Recurrent episodes of VT can compromise heart function and increase mortality. VT is prevented by special drugs but these are not always effective and can have many side effects. Most patients with VT will also have a specialised device called an implantable defibrillator (ICD) implanted. The ICD treats VT by either stimulating the heart rapidly or delivering a shock to it. ICDs are very effective but the shocks are painful and have a big impact on quality of life. If VT occurs despite optimal drug treatment, patients undergo an invasive procedure called catheter ablation. Here, wires are passed into the heart from the blood vessels in the leg and the damaged heart muscle causing the VT is identified whilst the heart is in VT. An electrical current is passed down the wire making its tip heat up allowing discrete burns (ablation) to be placed inside the heart. The ablated heart muscle doesn't conduct electricity which stops the VT and prevents it recurring. Some patients are so frail that ablation cannot be performed safely. A recent clinical trial has shown that VT can be treated in such patients using radiotherapy, which is usually used to treat tumours with high energy radiation. This approach is non-invasive, painless and requires no sedation or anaesthesia. This study will test whether VT can be successfully treated using stereotactic ablative radiotherapy. This can deliver high dose radiotherapy very precisely, whilst minimising the risk of damage to healthy tissues.

Autonomous Robotics for Transcatheter Cardiac Procedures

ARTERY
Start date: March 15, 2021
Phase:
Study type: Observational

Cardiovascular diseases represent the most common cause of death worldwide. Percutaneous approaches with intravascular catheters are pivotal, since they allow to treat patients with high perioperative risks. However, catheter-based treatments require steep learning curves and are characterized by poor ergonomics and exposure to damaging radiation. ARTERY will offer a radiation-free approach based on shared-autonomy robotic catheters, with increased user engagement and easy interaction. Intraprocedural three-dimensional echocardiography as well as computed tomography images obtained during usual clinical practice will provide artificial intelligence algorithms that will turn catheter navigation to a simple task. Optical and electromagnetic sensing techniques will ensure a superior view upon the cardiovascular anatomy and will guide the autonomous catheter upon the interventionist supervision, who will be able to take over control at any instant.
