Cardiac magnetic resonance (CMR) imaging could enable major advantages when guiding in real-time cardiac electrophysiology procedures offering high-resolution anatomy, arrhythmia substrate, and ablation lesion visualization in the absence of ionizing radiation. Over the last decade, technologies and platforms for performing electrophysiology procedures in a CMR environment have been developed. However, performing procedures outside the conventional fluoroscopic laboratory posed technical, practical and safety concerns.

Case Summary: A 64-year-old female patient with mechanical prosthetic valves underwent atrial fibrillation ablation using the pentaspline pulsed-field ablation catheter. At the end of the uneventful pulmonary vein isolation, an atrial tachycardia depended to the cavotricuspid isthmus occurred.
Article Synopsis
- Catheter ablation outcomes for non-paroxysmal atrial fibrillation (AF) are generally unsatisfactory, and using a non-invasive method to assess atrial cardiomyopathy (ACM) in patients could help identify those who would respond best to treatment.
- In a study of 295 patients who underwent cryoballoon-PVI, researchers measured the duration of amplified P-wave (APW) and found that those with a longer APW (≥150 ms) had a significantly higher recurrence rate of arrhythmia post-ablation compared to those with shorter APW (<150 ms).
- The study concluded that measuring APW is a simple, non-invasive way to predict which patients are more likely to have worse outcomes after PVI
