What is the purpose of this trial?

This trial tests a new device called the Globe Pulsed Field System to determine its safety and effectiveness in treating atrial fibrillation (AF), a condition causing an irregular and often rapid heart rhythm. The study targets individuals with symptoms who have not found success with at least one heart rhythm medication. Those with AF lasting less than a year and who have not undergone a heart procedure in the past six months may qualify for this trial. As an unphased trial, it offers participants the chance to contribute to groundbreaking research and potentially benefit from an innovative treatment.

Do I need to stop my current medications to join the trial?

The trial protocol does not specify if you need to stop your current medications. However, since it requires failure or intolerance of at least one antiarrhythmic drug, you might need to stop or have already stopped those specific medications.

Will I have to stop taking my current medications?

The trial does not specify if you need to stop taking your current medications. However, it mentions that participants must have failed or not tolerated at least one antiarrhythmic drug, which might imply changes to your medication.

What prior data suggests that the Globe Pulsed Field System is safe for treating atrial fibrillation?

Research has shown that the Globe Pulsed Field System is safe for treating atrial fibrillation (AF). Earlier studies reported no safety issues directly caused by the device, resulting in a 0% rate of device-related problems. The overall rate of safety issues was very low, at just 0.6%. Most participants tolerated the treatment well, with very few experiencing negative effects. These results support the safety of the Globe Pulsed Field System for those considering joining a clinical trial. ^{1 2 3 4 5}

Why are researchers excited about this trial?

Unlike traditional treatments for atrial fibrillation, such as radiofrequency ablation or cryoablation, the Globe Pulsed Field System uses a novel approach called pulsed field ablation. This technique uses short electrical pulses to selectively target and disrupt heart tissue responsible for abnormal rhythms, potentially offering greater precision and reducing damage to surrounding tissue. Researchers are excited about this treatment because it promises to minimize complications and improve recovery times compared to conventional methods.

What evidence suggests that the Globe Pulsed Field System is effective for atrial fibrillation?

Research has shown that the Globe Pulsed Field System, which participants in this trial will receive, effectively treats atrial fibrillation (AF), a common heart condition. One study found that 78% of patients with paroxysmal AF experienced no AF symptoms or related issues a year after treatment. Another study reported that the system helped 84.2% of individuals with paroxysmal AF and 80.0% of those with persistent AF maintain a normal heart rhythm for a year. These findings suggest that the system holds promise for effectively managing AF symptoms. ^{1 2 4 6 7}

Are You a Good Fit for This Trial?

This trial is for people with a type of heart rhythm disorder called symptomatic paroxysmal or persistent atrial fibrillation, who've tried at least one antiarrhythmic drug without success. It's not for those with long-term AF, related to reversible causes, recent heart issues or surgeries, very high BMI, severely reduced heart pump function, large left atrium size, or an implanted cardiac device.

Inclusion Criteria

I have been diagnosed with recurring AFib that comes and goes or stays.

I have tried and cannot tolerate or did not respond to a heart rhythm medication.

Exclusion Criteria

My atrial fibrillation is due to a temporary condition or not caused by heart disease.

I have not had a heart attack or any heart procedure in the last 3 months.

I have had a procedure done on the left side of my heart.

Pulsed field ablation (PFA) using the CENTAURI System achieved 100% pulmonary vein isolation in 82 patients with atrial fibrillation, demonstrating high efficacy with a first-pass isolation rate of 92.2%.

The study reported a favorable safety profile, with only four serious adverse events, indicating that optimized PFA is a viable and safe treatment option for atrial fibrillation when integrated with existing ablation techniques.

Pulsed field ablation achieved a 100% pulmonary vein isolation rate in 191 atrial fibrillation patients, demonstrating its efficacy as a safe and effective treatment option.

The procedure was streamlined to reduce average procedure times significantly, from 46 minutes to 38 minutes, while maintaining safety with no further strokes and a low incidence of silent cerebral injury.
