Filter by:A multi-center, observational registry conducted in Europe and the UK to prospectively review VIVO in a clinical setting in 125 patients.
This is an observational study of 10 Chagas Disease patients with Ventricular Tachycardia that have failed prior catheter ablation or have this procedure contraindicated due to clinical status. Those patients will underwent to Stereotactic Body Radiation Therapy (SBRT) targeting the area of the heart of the VT circuits. Radioablation target will be defined based on prior ablation electroanatomical mapping, VT morphology, pre-acquired imaging (CT angiogram, Cardiac Magnetic Resonance), current imaging reconstructed and integrated to electroanatomical mapping and a EP study to define current VT morphologies. Gross targeted volume (GTV), internal targeted volume (ITV) and planning targeted volume (PTV) will be defined and calculated and a single 25Gy dose will be delivered to the PTV. Patients will be followed initially for one year and efficacy endpoint will be rate of VT recurrence, time to recurrence and VT burden. Safety endpoint will be the occurrence of any adverse effect related to SBRT.
The purpose of this study is to assess the performance and safety for the use of the OPTRELL Catheter for intracardiac mapping in the atria and ventricles.
The multicenter Cardiology Monitoring Platform registry (mCMP-registry) is a prospective observational registry including multi-omics (diagnostic) measurements performed as part of routine clinical care, bio-banking (optional), and yearly questionnaires (optional). It's objective is to optimize (early) diagnosis and risk-stratification of (early) cardiovascular diseases, specifically cardiomyopathy phenotypes, arrhythmias, and coronary artery disease, and to create a better understanding of underlying pathophysiological processes.
This Open Label Extension study will enable eligible patients with Paroxysmal Supraventricular Tachycardia (PSVT) who have previously participated in a Milestone Pharmaceuticals clinical trial of etripamil NS for PSVT, to access continued treatment with etripamil NS, Patients who experienced any significant safety issues during participation period in a previous clinical trial of etripamil NS, as per Investigator's assessment , are excluded. This study will be conducted by Investigators who previously participated in a Milestone Pharmaceuticals clinical trial and are trained on the use of etripamil NS.
The investigators hope to learn the feasibility and preliminary efficacy of the Embr device for improving thermal comfort in individuals with POTS and impaired thermoregulation. Feasibility will be assessed via usage of the Embr device and participant feedback. Preliminary efficacy measures will include temperature-related symptoms and temperature- related quality of life in individuals with POTS and impaired thermoregulation.
This single-center observational registry follows contemporary efficacy and short-term complications of elective electric cardioversion.
CIED implants require different amounts of fluoroscopy; using 3-D mapping systems, these times could be reduced to near zero fluoroscopy. The investigators aim to describe to what extent fluoroscopy times are reduced on a routine basis on CIED implants
Sympathetic tone is important in cardiac arrhythmogenesis. The simultaneous recording of sympathetic nerve activity (SNA) and electrocardiogram (ECG) was obtained by invasive method. The purpose of this protocol is to further develop this recording method to turn it into a new non-invasive tool for arrhythmia prediction and detection. This method may also be useful in validating the results of surgical procedures aimed at sympathetic denervation
In Western countries, every sixth person in their lifetime and 15,000 people in Finland have a new stroke each year. About every fourth stroke is based on cardiac embolism. Atrial fibrillation (AF) is the most common arrhythmia that increases the risk of thromboembolic complications, such as stroke. It may cause formation of thrombi in the left atrium with ensuing embolization in the cerebral and peripheral circulation. AF is often asymptomatic and paroxysmal. Thus, the diagnosis of AF is often challenging. A new onset AF is usually treated with cardioversion (CV), in which the abnormal rhythm is converted back to sinus rhythm (SR). However, a long-lasting AF (>48 hours) is associated with risk of stroke. Therefore, the duration of AF needs to be known before a CV can be performed. This study evaluates the ability of novel customer-targeted heart measuring devices to detect rhythm change and short AF episodes. Moreover, novel biomarkers will be analyzed from the blood samples of AF patients and their suitability to estimate the duration of AF will be evaluated. The research will be accomplished in cooperation with the Kuopio University Hospital Emergency Department, the Heart Center, the Department of Applied Physics of the University of Eastern Finland and Heart2Save Ltd. The results of the research project will be published in the scientific journals of medicine and medical technology and will be presented at scientific conferences of the respective fields. The research results of the project can be utilized by all companies in the medical technology industry, in particular companies that produce ECG measuring instruments and companies that produce rhythm recognition software.
