    Description of Event or Problem · 0

    PER LITERATURE REVIEW, IT WAS REPORTED THAT: IN THIS SINGLE-CENTER STUDY AT THE UNIVERSITY CLINICAL HOSPITAL OF VALENCIA BETWEEN OCTOBER 2022 AND DECEMBER 2023, FORTY-FIVE PATIENTS WITH SYMPTOMATIC PAROXYSMAL AND PERSISTENT ATRIAL FIBRILLATION UNDERWENT PULMONARY VEIN ISOLATION WITH PULSE FIELD ABLATION (PFA). AT 24 HOURS AFTER THE PROCEDURE, PATIENTS UNDERWENT A 1.5T BRAIN MAGNETIC RESONANCE IMAGING(MRI) SCAN TO DETECT NEW ISCHEMIC OR HEMORRHAGIC BRAIN LESIONS. AS A RESULT, THREE PATIENTS SHOWED NEW LESIONS ON THE BRAIN MRI SCAN. ONE PATIENT EXPERIENCED A TRANSIENT ISCHEMIC ATTACK (TIA) WITH MIXED APHASIA, RECOVERING WITHIN THE NEXT 24 HOURS, AND TWO PATIENTS HAD SILENT CEREBRAL LESIONS (SCLS). PATIENTS WITH BRAIN LESIONS EXHIBITED A SIGNIFICANTLY LARGER LEFT ATRIAL VOLUME THAN THOSE WITHOUT LESIONS. IN THE 2 PATIENTS WITH SCL, LESION RESOLUTION WAS CONFIRMED ON THE FOLLOW-UP MRI SCAN. THE PATIENT WITH TIA HAD A LESION IN THE LEFT PARIETAL REGION ASSOCIATED WITH TRANSIENT MIXED APHASIA. HE WAS A 51-YEAR-OLD MAN WITH PERSISTENT AF DIAGNOSED IN 2022. CARDIOVERSION WAS PERFORMED DURING THE ABLATION. THE TOTAL PROCEDURE TIME WAS 105 MINUTES. IN 1 OF THE PATIENTS WITH SCL, A SINGLE LESION IN THE RIGHT SEMI-OVAL CENTER MEASURING 5 BY 4 MILLIMETER WAS DOCUMENTED. HE WAS A 64 YEAR OLD MAN WITH PERSISTENT ATRIAL FIBRILLATION DIAGNOSED IN 2022. THE OTHER PATIENT WITH SCL ON MRI SHOWED A SINGLE LESION IN THE RIGHT CEREBELLAR REGION MEASURING 6 B 4 MILLIMETER. SHE WAS A 71 YEAR OLD PATIENT WITH A HISTORY OF ISCHEMIC HEART DISEASE, DIAGNOSED WITH PAROXYSMAL ATRIAL FIBRILLATION. IN FOLLOW-UP, THE PATIENT WITH TIA REFUSED FURTHER CONTROL MRI SCANS. THE TWO PATIENTS WITH THE SCL UNDERWENT A NEW CEREBRAL MRI SCAN AT 90 DAYS, CONFIRMING IN THAT THE LESIONS HAD HEALED WITHOUT CHRONIC SCARRING. NO DEVICE IS EXPECTED TO RETURN AS THIS IS FROM A LITERATURE REVIEW.
