NCT ID: NCT05890716 Recruiting - Cardiac Arrest Clinical Trials

AI-powered ECG Analysis Using Willemâ„¢ Software in High-risk Cardiac Patients (WILLEM)

WILLEM
Start date: April 4, 2023
Phase:
Study type: Observational

WILLEM is a multi-center, prospective and retrospective cohort study. The study will assess the performance of a cloud-based and AI-powered ECG analysis platform, named Willemâ„¢, developed to detect arrhythmias and other abnormal cardiac patterns. The main questions it aims to answer are: 1. A new AI-powered ECG analysis platform can automatice the classification and prediction of cardiac arrhythmic episodes at a cardiologist level. 2. This AI-powered ECG analysis can delay or even avoid harmful therapies and severe cardiac adverse events such as sudden death. The prerequisites for inclusion of patients will be the availability of at least one ECG record in raw data, along with patient clinical data and evolution data after more than 1-year follow-up. Cardiac electrical signals from multiple medical devices will be collected by cardiology experts after obtaining the informed consent. Every cardiac electrical signal from every subject will be reviewed by a board-certified cardiologist to label the arrhythmias and patterns recorded in those tracings. In order to obtain tracings of relevant information, >95% of the subjects enrolled will have rhythm disorders or abnormal ECG's patterns at the time of enrollment.

NCT ID: NCT05724121 Recruiting - Clinical trials for Mantle Cell Lymphoma

Observational Study of Cardiac Arrhythmias During Treatment With BTK Inhibitors or Venetoclax

Start date: March 1, 2023
Phase:
Study type: Observational

Background: Bruton s tyrosine kinase inhibitors (BTKi) are used to treat a form of leukemia. But taking BTKi can also increase a person s risk of developing an abnormal heart rhythm. This can cause sudden death. In this natural history study, researchers want to learn how BTKi affects the heart. Objective: To identify and monitor the effects of BTKi on the heart. Eligibility: People aged 18 and older currently receiving or planning to receive BTKi or venetoclax. Design: Participants who have not yet started BTKi will have 2 required clinic visits: 1 before they start taking BTKi, and 1 about 6 months later. Participants who are already taking BTKi will have 1 required visit. Participants will undergo multiple tests: A physical exam, including collection of blood and saliva. A test that measures heart activity via stickers placed on the chest. A test that uses sound waves to capture images of the heart. An exercise stress test that monitors heart activity and blood pressure while the participant works on a treadmill or stationary bike. Sound wave images of the heart may also be taken while the participant exercises. Stress magnetic resonance imaging (MRI) may be done in place of an exercise test. Participants will lie on a table that slides into a tube. They will be given drugs to stress the heart while images are taken. Participants may wear a device to monitor their heart at home. Participants may have repeat visits if they develop heart symptoms or if they need to stop taking BTKi. They will have follow-up phone calls each year for up to 3 years.

NCT ID: NCT05450302 Not yet recruiting - Cardiac Arrhythmias Clinical Trials

Assessing the Predictive Value of High Frequency Algorithm of PURE EP for Low Amplitude Signal Detection

Start date: April 2023
Phase:
Study type: Observational

Prior multicenter study demonstrated superiority of PURE EP to conventional mapping. This superiority was seen when comparing small, fractionated signals of interest, near-field vs far-field distinction, and general signal quality (2). Hence, investigators propose a retrospective study to assess the predictive value of high frequency algorithm (HFA) for identifying local physiologic signal under 0.3 mV distinctive of noise.

NCT ID: NCT05175937 Recruiting - Heart Failure Clinical Trials

REal World Assessment for Patients Implanted With Implantable CardioverTer DefibrIllatOr Using Bluetooth Technology

REACTION
Start date: September 22, 2021
Phase:
Study type: Observational

The objective of this observational study is to assess clinical benefits of innovative features (e.g. Bluetooth technology and smartphone patient applications) in a patient population that is implanted with standard indication for implantable cardiac defibrillator.

NCT ID: NCT05005143 Not yet recruiting - Atrial Fibrillation Clinical Trials

Improved Procedural Workflow For Catheter Ablation Of Paroxysmal AF With High Density Mapping System And Advanced Technology

DELETE AF
Start date: September 1, 2021
Phase:
Study type: Observational

DELETE AF is a prospective, multicenter, non-randomized post-market study. All patients will be treated according to the standard care followed by each center. The protocol requires enrollment of consecutive patients from each center, according to eligibility criteria. During the 12 months follow-up period, clinical atrial fibrillation recurrence, occurrence of all kind of atrial arrhythmias and of all Adverse Events in the study population will be collected. The purpose of this study is to demonstrate a low rate of clinical atrial arrhythmias recurrence with an improved procedural workflow for catheter ablation of paroxysmal AF, using the most advanced point-by-point RF ablation technology in a multicenter setting. The primary objective of the study is the rate of success at the medium-long term follow-up after PVI in a population of consecutive patients undergoing paroxysmal AF ablation. The success of the ablation is defined in terms of percentage of patients free from any clinical atrial arrhythmia at a 12-month follow-up from the procedure.

NCT ID: NCT04750798 Recruiting - Cardiac Arrhythmias Clinical Trials

An Observational Post-marketing Study Using Commercially Approved Biosense Webster (BWI) Medical Devices for the Treatment of Participants With Cardiac Arrhythmias

Start date: February 22, 2021
Phase:
Study type: Observational

The purpose of this study is to prospectively collect clinical data evaluating the ongoing safety and performance during routine-use standard cardiac arrhythmia mapping and/or ablation procedures while using commercial Biosense Webster Inc. (BWI) medical devices. Data generated from the study will be used to confirm safety and performance of BWI medical devices in the marketed phase and to expand the body of evidence on the use of these devices and techniques in treatment of cardiac arrhythmias.

NCT ID: NCT04361006 Completed - Cardiac Arrhythmias Clinical Trials

Cryotherapy Versus Radiofrequency Ablation for Treatment of Para-hisian Accessory Pathways

Start date: October 1, 2018
Phase: N/A
Study type: Interventional

A randomized pilot study to evaluate safety and efficacy endpoints for treatment of para-hisian accessory pathways according to two different strategies of lesion formation. These patients will be divided into 2 groups with different strategies of treatment: group 1 treated with radiofrequency (RF) ablation, group 2 with cryotherapy (CRYO). The primary outcome will be the recurrence rate of accessory pathway conduction after one year of follow-up. Secondary endpoints will be immediate success and rate of permanent atrioventricular (AV) block.
