It was reported that a (b)(6) male patient underwent an ischemic ventricular tachycardia - left (isvt- left) ablation procedure with a thermocool® smart touch¿ bi-directional navigation catheter and suffered ventricular fibrillation (vfib) requiring cpr, defibrillation, medications.The patient expired.During the procedure, the team mapped an episode of ventricular tachycardia (vt) on the left ventricle (lv) and made 3 radiofrequency (rf) applications on site of interest (within normal parameters).Before finishing last application, patient developed vfib.Physicians tried to defibrillate on many occasions and revert it with drugs, without success.After 30min of cardiopulmonary resuscitation (cpr), the patient died.There was no presence of pericardial effusion on echocardiography (echo).The procedure was not completed.Additional information received on 7-feb-2022.The date of death was (b)(6) 2022.The physician¿s opinion on the cause of death is that it is patient condition related (ventricular electrical storm (ves)).The force visualization features used were graph, dashboard, vector & visitag with the visitag module parameters for stability set to maximum distance change 3mm; minimum time 3s; force over time 25%; minimum force 3g.The additional filters used with the visitag were respiration adjustment and tag index.The generator used was a stockert st-0409 (ep shuttle sys 100w).
