It was reported that a (b)(6)-year-old male patient ((b)(6) lb) underwent an ischemic ventricular tachycardia (isvt) ablation procedure with a thermocool® sf bi-directional catheter and suffered cardiac tamponade (requiring pericardiocentesis) ventricular fibrillation and cardiac arrest (requiring cardiopulmonary resuscitation (cpr)).During the procedure while ablating at 50 watts in the left ventricle (lv) the physician performed a pacing protocol, the patient was hemodynamically stable; however, it was noticed that the patient¿s heart rhythm changed to ventricular tachycardia (vt), and then degraded into ventricular fibrillation (vfib).Cardiopulmonary resuscitation protocols were performed by the medical staff for about 3-4 minutes until the implantable cardioverter defibrillator (icd) was able to restore the rhythm and start pacing.There was a slow rise in the impedance when the physician was ablating in the right ventricle (rv) but there was no high force values or drastic impedance changes throughout the procedure.The physician confirmed the presence of pericardial effusion and a suspected perforation to the rv or lv apex.Cardiac tamponade was confirmed by soundstar catheter and pericardiocentesis was performed to remove about 20ml of fluid from the pericardial space.Pericardial drainage tube was left in place and the patient was admitted and transferred to the operating room (or).The patient was stable but with a significant effusion while leaving the ep lab.The patient coded again while in route to the or, and the medical staff performed cpr protocols, drained the effusion and were able to revive the patient.It is unknown if a procedure was performed in the or.Patient¿s condition improved.There¿s no information on if extended hospitalization was required.Physician¿s opinion regarding the cause of the adverse event is that the rv as perforated with the ablation catheter.Transseptal puncture was performed with a baylis transseptal needle.There was no evidence of steam pop during the ablation.The catheter flow was set at 15ml/min.The force visualization features used included graph, dashboard, vector and visitag.Visitag settings were 2.5 mm for 3 seconds at 3g of force.Time was used as color option.The max wattage used during the case was 50 watts.The total rf lesions were about 100.The total fluid drained was 2,500ml and the total procedure time was about 6 hours.No bwi product malfunction was reported.
