This complaint is from a literature source.It was reported that 133 (4-fps group, n=57; 2-fps group, n=76) patients with atrial fibrillation disease underwent catheter ablation from january 2014 and may 2015.Among them, one patient had experienced a cerebellar stroke 1 day after the procedure, and achieved a full neurological recovery in the 2-fps group.Based on the facts of the case and the author¿s assessment, there were no reported malfunction with any of the bwi catheters and systems used during the case.Thus, this event is unrelated to the device and most likely related to the procedure.Title: ¿extremely low-frame-rate digital fluoroscopy in catheter ablation of atrial fibrillation a comparison of 2 versus 4 frame rate.¿ the purpose of this study was to comparison of 2 versus 4 frame rate.Suspect device is a thermocool smarttouch or navistar thermocool sf, however catalog and lot number is unknown.
