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

ABSTRACT

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.
