This complaint is from a literature source.It was reported that one (b)(6) patient (patient #23) with scar-related ventricular tachycardia (vt) underwent radiofrequency ablation and developed uncomplicated bilateral lower-extremity deep venous thrombosis that was successfully treated with anticoagulation.Patient's medical history includes incessant monomorphic vt, icd storm.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: ¿remote magnetic navigation to guide endocardial and epicardial catheter mapping of scar-related ventricular tachycardia¿ the purpose of this study to examine the safety and feasibility of using a remote magnetic navigation system to perform endocardial and epicardial substrate-based mapping and radiofrequency ablation in patients with scar-related ventricular tachycardia.The study was conducted between november 2005 and october 2006.Suspect devices are remotely guided, 4-mm-tip, navistar quadripolar (rmt) catheter, however catalog and lot number is unknown.
