Filter by:In 2017 a novel treatment approach to a series of 5 patients with refractory VT was introduced, using ablative radiation with a stereotactic body radiation therapy (SBRT) technique to arrhythmogenic scar regions defined by noninvasive cardiac mapping. More recently, Robinson et al. reported on the results of their Electrophysiology-Guided Noninvasive Cardiac Radioablation for Ventricular Tachycardia (ENCORE-VT) trial, also using a similar SBRT technique in a series of 17 patients with refractory VT. Both studies report a marked reduction in VT burden, a decrease in antiarrhythmic drug use, and an improvement in quality of life. Since then, numerous other centres have detailed their initial experience with this technique. These initial results suggest that this new treatment paradigm has the potential to improve morbidity and mortality for patients suffering from treatment-refractory VT by means of a minimally invasive technique, but requires further validation for widespread use. The appropriate dose for therapeutic effect of this new treatment is not well established as only a single dose prescription of 25 Gy in 1 fraction has been described with benefit. In this phase 2 trial, the investigators plan on expanding the experience with this technique but also by contributing to understanding the relationship between dose-effect relationship through a dose de-escalation stratification, to 20 Gy in 1 fraction, with the goal of minimizing possible adverse events and radiation dose to surrounding healthy tissue while maintaining a clinical benefit.
Prospective, non-randomized, multi-center, international study designed to evaluate the safety and effectiveness of the Aveir™ Dual-Chamber (DR) Leadless Pacemaker system.
In a cohort of patients electively treated for atrial arrhythmia with IV sotalol (initiation or dose escalation), this study will describe patient characteristics, short-term safety and efficacy, electrocardiographic monitoring, and PK and PD parameters (in a subset) associated with IV dosing approach.
Ablation of consecutive atrial tachycardia (AT) after ablation of atrial fibrillation (AF) or cardiac surgery can be challenging due to complex substrate and AT mechanisms. A substantial portion of patients is known to show various tachycardias and recurrences occur in a noticeable number of cases. With the availability of novel ultra-high-density mapping techniques characterization and understanding of AT mechanisms and underlying substrate can be improved. Aim of this prospective, multi-center, randomized study is to compare a standard AT ablation approach versus minimalized ablation of the clinical AT in regards to arrhythmia free survival.
All calls that end up on the out-of-hours general practitioners' service (OHGPS), which contain a demand for an urgent home visit, are passed on to the on-call general practitioner (GP). These calls are randomized into two arms: after the patient's informed consent, they are assigned either to one arm where the monitoring device, PICO, is applied together with the GP's general care or to the other arm where only the usual care is provided. All data such as suspected diagnosis, treatment or referral, influence of the parameters, ECG and/or alarms on the management and the user-friendliness are recorded. After 30 days, the diagnosis and evolution is requested from the patient's own GP or, if referred to a hospital, in the hospital in order to be able to compare the effect of the approach by the GP between both arms. The aim is to investigate if 1/ the use of the PICO monitoring device could improve GPs' decisions to refer to hospital or not in urgent cases; 2/ there is a difference between the diagnosis with and without the use of the monitoring device using the final diagnosis by the electronic health record of the own GP of the patient; 3/ the call to send a GP for an emergency contained sufficient information for the OHGPS phone operator to take an appropriate decision; 4/ the build-in alarms help the GP during his intervention; 5/ the PICO is easy to use during an emergency; 6/ the use of the device makes them feel more confident in transmitting the information to the Medical Emergency Team.
To detect atrial fibrillation after infection.
The trial is a prospective, non-randomized, single-arm feasibility trial to evaluate physician acceptance of the NeuTrace System v1.0 for cardiac electroanatomic mapping.
About 30% of ischemic strokes are cryptogenic. Patent Foramen Ovale (PFO) is present in about 25% of the general population. In cryptogenic strokes, PFO has been shown to be overrepresented and recent intervention studies have confirmed that PFO has a causal link with stroke. In patients with recent cryptogenic stroke, these randomized studies have shown at least 50%-reduction of recurrent neurological events after PFO percutaneous closure compared with medical therapy alone. At the The risk of AF reported in these studies in certainly largely underestimated as only symptomatic and recorded episodes of AF have been declared. Patients often report palpitations without a dia gnosis of AF made on the ECG or a Holter. Long term ECG monitoring provides more accurate data on AF incidence. Administration of flecainide has been shown to be effective in preventing Atrial arrhythmia and may be useful in preventing these Atrial arrhythmia(AA) episodes after PFO closure. To the knowledge of the investigators, there is no study assessing the efficacy of any antiarrhythmic drug in the prevention of AFafter PFO closure. AFLOAT will be the first randomized study to possibly validate flecainide to prevent Atrial arrhythmia in these patients.
After one-stage hybrid arrhythmia ablation surgery there are possible side effects like acute and chronic pain. There is a lot of research surrounding these pains but not specifically after one-stage hybrid arrhythmia ablation surgery. The investigators want to research factors that may be associated with the absence of chronic pain after hybrid ablation include ketamine, peroperative opioids, loco-regional blocks, neuraxial blocks, wound infiltration, postoperative patient-controlled analgesia. The presence of corticosteroids or NSAIDS, will also be evaluated. Furthermore, non-adaptable factors such as genetics complicate the onset of chronic post-operative pain. Taking existing knowledge in this field into account, incidence risk as well as acute pain duration and intensity and their effects on chronic pain will become the primary focus of this study. The investigators will contact all patients who had a one-stage hybrid arrhythmia ablation surgery at UZ Brussels. Participants will be sent a questionnaire with a consent form in and a survey asking about their pain 3 months postop and their current pain management therapy.
Electrocardiography is one of most basic laboratory tests in cardiology. Novel mobile ECG are becoming popular. The investigators aim to compare typical electrocardiographic measurements obtained with mobile ECG devices (Alivecor Kardia and Alivecor Cardia 6L) and 12-leads standard ECG (gold standard). The recordings will be compared by cardiologist paying special attention to heart rhythm disturbances, components of ECG curve and quality of recording.
