Transvenous Implantation of an Implantable Cardioverter Defibrillator in a Patient Who Had Undergone Tricuspid Valve Replacement

Transvenous implantation of an implantable cardioverter defibrillator in patients with a prosthetic valve in the tricuspid position is difficult because a defibrillator lead cannot be implanted into the right ventricle through the prosthetic valve. Hence, there are three options: epicardial implantation, subcutaneous implantable cardioverter defibrillator implantation, and cardiac vein implantation. Here, we report the transvenous implantation of an implantable dual-chamber cardioverter defibrillator in a patient who had undergone tricuspid valve replacement with a prosthetic valve. The patient was a 70-year-old female with a prosthetic valve in the tricuspid position who had experienced two events of sudden cardiac arrest. We successfully performed the procedure by implanting the defibrillator lead into the middle cardiac vein. (
