This complaint is from a literature source.It was reported that a (b)(6) patient underwent an radiofrequency ablation for ventricular tachycardia and developed a small pericardial effusion¿attributed to concomitant pericardial access¿and 250 ml of bloody fluid was drained from the pericardium at the end of the procedure from the preexistent pericardial access.The patient underwent cardiac magnetic resonance imaging 48 hours post procedure.It revealed significant expansion of basal anteroseptal hyperenhancement, indicative of ethanol-induced injury.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: ¿retrograde coronary venous ethanol infusion for ablation of refractory ventricular tachycardia.¿ the purpose of this study was to report its combination with venous wire mapping in a variety of vt substrates, particularly the lv summit, and report its chronic outcomes.Seven (7) patients were included in this study.Suspect device is pentaray catheter, however catalog and lot number are unknown.
