Evaluation of Ablation Lesions Using Cardiovascular Magnetic Resonance Imaging
Source: ClinicalTrials.gov · Last updated 28 Jul 2025 · Not updated for over 12 months - ask the site whether it is still open
Brief summary (registry, in English)
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.
