Filter by:The goal of this clinical trial is to compare two ablation techniques to treat patients with persistent atrial fibrillation (irregular and often very rapid heart rhythm). An ablation is a procedure during which some scars are made on the inside of the heart to break up the electrical signals that cause the irregular heartbeat. In this trial researchers will compare a new technique, which uses tiny electric shocks to make the scars, to the standard technique, which uses heat. The main question the trial aims to answer is: • Does the new technique work as well as the standard technique to prevent the irregular heartbeat from returning within one year of the procedure? Participants will: - Undergo an ablation with either the new or the standard technique - Visit the hospital 1, 3, 6, 9 and 12 months after the procedure for a check-up - Wear a device to register their heart rhythm for 24 hours before the 3 month visit and for 72 hours before the 6, 9 and 12 month visit - Record their heart rhythm at home every week - Complete a questionnaire 3, 6, 9 and 12 months after the procedure
The goal of this clinical trial is to determine the effect of accelerated pacing (pacemaker lower rate programmed to 80bpm) compared to pacing at the standard programmed lower rate of 60bpm in symptomatic atrial fibrillation patients undergoing pace-and-ablate strategy with LBBAP. The main question it aims to answer is: - To determine the effect of accelerated pacing on health-related quality of life compared to the current standard of care. Secondary questions it aims to answer are: - To study the acute hemodynamic effect of different (accelerated) pacing rates on pulmonary capillary wedge pressure, cardiac output and arterial blood pressure among atrial fibrillation patients undergoing pace-and-ablate strategy. - To study the long-term effects (at 6 months) of accelerated pacing compared to the current standard of care among atrial fibrillation patients undergoing pace-and-ablate strategy on: - NT pro BNP levels - device detected atrial fibrillation burden and daily activity - echocardiographic measurements (LVEF, left ventricular ejection fraction; LVEDD, left ventricular end- diastolic diameter; LVESD, left ventricular end-systolic diameter; LAVI left atrial volume index; diastolic parameters; strain
Compare the efficacy and safety between pulmonary vein isolation (PVI) alone versus PVI with left atrial (LA) posterior wall isolation (PWI) using pulsed-field ablation (PFA) in the treatment of patients with paroxysmal atrial fibrillation (PAF).
The purpose of this study is to compare and assess efficacy and safety between the study device "TS-RF system consisting of a electrosurgical system, general-purpose (TS-RF Generator) and a electrosurgical system electrode, hand-controlled, general-purpose, single-use (TS-RF Needle)" and the control device "needle, puncture, single-use (BRK Transseptal needle)", both of which are used for the transseptal puncture performed to enable left atrial access for the treatment of symptomatic arrhythmia and mitral stenosis and then to demonstrate that the study device is non-inferior to the control device.
Atrial fibrillation (AF) is the most preventable cause of stroke. However, despite widely available risk stratification tools, numerous options for oral anticoagulation, and evidence-based practice guidelines, anticoagulation for stroke prevention in AF is consistently under-prescribed. In a pair of observational cohort analyses within the Mass General Brigham (MGB) health system, prescription of anticoagulation for stroke prevention in AF was less frequent in ambulatory clinic patients than in those who were hospitalized at the time of assessment (46.9% vs. 57.2%). Two single academic medical center randomized controlled trials demonstrated success for increasing adherence to guideline recommendations for stroke prevention in AF. To address the feasibility and impact of a computerized decision support (CDS) strategy in the non-tertiary care, community medical center setting, this study will involve a multicenter, cluster-randomized controlled trial of a more sophisticated CDS focused not only on implementation stroke prevention but also on bleeding risk assessment and management.
This feasibility study will be conducted to demonstrate the initial safety and effectiveness of the CellFX® nsPFA™ Cardiac Clamp in performing a box lesion around the 4 pulmonary veins as an isolated procedure or as a part of a more extensive surgical ablation set in conjunction with concomitant cardiac surgical procedure.
This is a multi-center sub-study examining the effectiveness of active esophageal cooling on subjects undergoing left atrial ablation for symptomatic Paroxysmal Atrial Fibrillation or Persistent Atrial Fibrillation.
The aim of the study is to evaluate the performance of Withings SCT02 with embedded Withings ECG-app in the automatic detection of atrial fibrillation
Pulmonary vein (PV) isolation is considered the therapeutic strategy of choice to maintain sinus rhythm (SR) in symptomatic patients with atrial fibrillation (AF). The most commonly used energy modality is radiofrequency (RF). However, this type of energy presents notable challenges, such as its lack of selectivity for myocardial tissue, which increases the risk of serious complications such as atrioesophageal fistula, PV stenosis, and vagus nerve injuries. In this context, PV isolation using pulsed field ablation (PFA) emerges as a promising alternative due to its greater myocardial selectivity. However, this selectivity presents additional challenges. Preliminary studies indicate that PFA may not damage the autonomic nervous system (ANS) involved in the initiation and maintenance of AF in certain patients, although stronger evidence is needed to support this claim. The investigators propose to carry out a single-center clinical trial, although with the possibility in the future of including other centers. Patients will be randomized to three research groups: PV isolation with RF, PV isolation with PFA, and PV isolation combining PFA and RF (using RF on the anterior wall and PFA on the posterior wall). This assignment will be open to the operator who performs the procedure, but blind for the researcher responsible for monitoring and for the data analyst. The objective is to compare the impact of different energy sources during PV isolation on the ability to produce a permanent alteration in the ANS. The hypothesis is that combined PF isolation will be capable of producing a permanent alteration of autonomic function parameters superior to ablation using exclusive PFA.
The INTELICE trial is a prospective, multicenter, 1:1 randomized controlled non-inferiority study. It aims to compare a novel intracardiac echography (ICE) catheter and combined ultrasound system with existing commercial ones. The evaluation will be conducted on patients undergoing planned intracardiac interventional process.
