An original defibrillation lead implantation to avoid tricuspid prosthesis damage.
We report the case of a 67-year-old woman suffering from Ebstein's disease, who underwent three cardiac operations for bypass, tricuspid prosthesis and pacemaker implantation, and who needed an implantable cardioverter defibrillator for recurrent syncopes related to ventricular tachycardia. Because of the tricuspid prosthesis we chose to implant the defibrillation lead in the inferior vena cava. We collected satisfactory pacing and sensing data and performed a successful defibrillation test during the procedure. This configuration appears to be a safe alternative to conventional implantation in the coronary sinus, as already described in the literature for a few cases.
