Evaluation of Ablation Lesions Using Cardiovascular Magnetic Resonance Imaging

Sponsor

R&D Cardiologie

Enrollment

60 participants

Start Date

Mar 8, 2023

Study Type

OBSERVATIONAL

Conditions

Atrial Fibrillation

Summary

Ineffective ablation lesions can cause arrhythmia recurrence after catheter ablation for cardiac arrhythmia. Ablation lesions can be created with various ablation energy modalities. This study uses cardiovascular magnetic resonance imaging to evaluate the ablation lesion characteristics of radiofrequency ablation, ultra-low temperature cryo ablation, and pulsed field ablation. The ablation lesion characteristics of different energy characteristics will be compared. Additionally, arrhythmia recurrence and quality of life will be evaluated for the different energy modalities.

Eligibility

Min Age: 18 Years

Plain Language Summary

Simplified for easier understanding

This study is using cardiac MRI (a special heart scan) to evaluate how well different techniques for treating an irregular heartbeat (atrial fibrillation) are working. By looking at the scars created by the treatment procedure, researchers hope to better understand why some patients respond better than others. **You may be eligible if:** - You are 18 or older - You have atrial fibrillation (paroxysmal or persistent — either intermittent episodes or ongoing) - You are scheduled to have a catheter ablation procedure for your heart arrhythmia **You may NOT be eligible if:** - You have a known allergy to gadolinium (the contrast dye used in MRI) - You cannot have an MRI (e.g., due to claustrophobia, certain metal implants, or very high body weight) - You are pregnant or breastfeeding - You have previously had a procedure on the left side of your heart (ablation or surgery) Talk to your doctor to see if this trial is right for you.

Interventions

DEVICECatheter ablation

An ablation catheter is introduced in the heart. Ablation is performed by applying ablation energy to the target tissue. The aim of ablation is to create an ablation lesion that does not conduct the electrical signals that induce or sustain the cardiac arrhythmia.
