Filter by:Intracardiac echocardiography (ICE), has been an essential component of Radiofrequency (RF) ablations for AF given its association with decreased fluoroscopy time and complication rates, and therefore it is logical that this can be applied to CTI ablations for AFL as well. There are however no studies to date that directly focused on the benefits of adding ICE during CTI dependent AFL ablation. Currently it is not required that operators use ICE in every case of AFL ablation. Investigators intended to study the routine use of ICE in such cases and to see if there is a significant benefit in routine use of ICE.
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.
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.
This study is proposed herein is to gather clinical data on the safety and performance of the CRYOF device. Specifically, data from this study will be used for submission to regulatory authorities in Europe, China and other geographies as needed.
Unicenter, 1:1 randomized, open-labelled clinical trial comparing left atrial flutter ablation using high density mapping or strict lineal ablation. Main outcome: arrhythmia recurrences over 1 year follow-up with daily 1-lead 30 seconds ECG samples.
The study aims to evaluate and compare the incidence of atrial arrhythmias (including Post-Operative Atrial Fibrillation (POAF), atrial flutter, and atrial tachycardia) stratified by baseline Utah fibrosis stages and overall fibrosis (%) of the left atrial wall area. The investigators hypothesize that patients with a higher baseline Utah fibrosis staging will experience a higher incidence of POAF. The study also aims to evaluate and compare the in-hospital mortality, length-of-stay (LOS), complication rates (strokes, pneumonia, respiratory failure etc.) of the different Utah fibrosis stage cohorts. Perform cost analysis and compare between patients with POAF and patients without POAF. The investigators hypothesize that patients experiencing POAF will have a higher mortality rate, longer LOS, greater complications, and therefore, additional hospital costs.
Atrial fibrillation (AF) is a major public health problem: it impairs quality of life and independently heightens the risks of ischemic stroke, heart failure and all-cause mortality. AF is a common reason for presenting to emergency departments (ED) in Kaiser Permanente Northern California (KPNC) and is associated with frequent hospitalization. Additionally, inter-facility hospitalization rates for AF vary across KPNC. Improvements in modifiable components of ED AF care could potentially reduce low-yield hospitalizations and the associated costs, patient inconveniences, and complications that can ensue. Real-time clinical decision support systems (CDSS) can transform entrenched physician practices and improve patient outcomes. The investigators will conduct a stepped-wedge cluster randomized trial of a CDSS intervention across 13 KPNC EDs for the comprehensive management of acute AF with the following three aims: 1) To evaluate the impact of the CDSS intervention on index hospitalization rates; 2) To evaluate the impact of the CDSS intervention on ED AF rate and rhythm control process-of-care metrics; and 3) To evaluate the impact of the CDSS intervention on AF stroke prevention actions for eligible participants at the time of ED discharge. The investigators hypothesize that the CDSS intervention will safely reduce index hospitalization rates, improve rate and rhythm control process-of-care metrics, and increase stroke prevention actions for eligible participants at ED discharge and within 30 days.
This single-center observational registry follows contemporary efficacy and short-term complications of elective electric cardioversion.
To validate omnipolar mapping in a well-described circuit within the heart (Atrial Flutter) and compare it with the gold standard of Local Activation Time (LAT) mapping during routine, clinically indicated procedures of Atrial Flutter ablation. A conventional, LAT map will be created during the procedure, prior to treatment, to guide the procedure. A repeat map will be performed after ablation during the procedure. The investigators will export the map files for off-line analysis with the omnipolar software.
This research will investigate the PPG signal morphology related to physiological and non- physiological changes in arrhythmia-related heart rate as well as the performance of the PPG-based features previously developed within the framework of the Mini-Holter study to discriminate between several cardiac arrhythmias. To this end, clinical data will be recorded on patients by using a wrist-based PPG monitor simultaneously with 12-lead ECG and intracardiac electrogram (EGM) signals at the university hospital in Lausanne. Importantly, this study will remain purely observational as it will not change the diagnostic and therapeutic management of the included patients, nor will it interfere with the time course of the procedures. The aim of enHEART study is to validate on a larger database the ability of several previously developed PPG-based features to detect a variety of cardiac arrhythmias.
