SUV max on the PV antrum was significantly higher than that on the healthy LA wall. The volume of the atrial inflammation was strongly correlated with that of the atrial fibrosis.

A consecutive 10 paroxysmal atrial fibrillation patients after the cryoballoon ablation (CBA) were enrolled. The patient characteristics are shown in Table 1. The mean age was 54 +/- 15 years old and 9 patients were male. The mean left atrial diameter (LAD) and left ventricular ejection fraction (LVEF) were 38 +/- 6 mm and 62 +/- 9 %, respectively. As for the procedural data, the CBA procedure time and fluoroscopy time were 167 +/- 38 min and 46 +/- 20 mm, respectively. Radiofrequency touch-up ablation for the RIPV was performed in 1 (10%) of 10 patients. The cardiac rhythm was sinus rhythm (SR) at the time of the PET/MRI and LGE-MRI acquisition in all patients.
This study was an open-label, single-arm, prospective clinical trial and was registered with the University Hospital Medical Information Network-Clinical Trial Registry (UMIN-CTR) (UMIN000027417) and Japan Registry of Clinical Trials (jRCT) (jRCTs 052180024). The protocol for this study was approved by the local ethics committees of the institutions and conformed to the provisions of the Declaration of Helsinki (Committee of 17 August 2019, Approval No.C180014).The detailed protocol has been described previously.(7) The primary endpoint was the visualization of the atrial inflammation by the PET/MRI. The secondary endpoint was the atrial fibrosis following atrial inflammation.
No adverse events.
We assess whether the atrial inflammation caused by CBA could be visualized by PET/MRI and whether it was associated with the followingfibrosis in AF patients.
