Can permanent pacing of the left ventricle be achieved via transvenous implantation of a steroid-eluting electrode into the coronary sinus in a patient with a Fontan circulation?
Transvenous implantation of a pacemaker electrode into the coronary sinus offers a viable approach for left ventricular pacing in patients lacking transvenous access to the right ventricle, such as those with a Fontan circulation.
Permanent pacing of the left ventricle was achieved by transvenous implantation of a steroid-eluting electrode into the coronary sinus in a patient who had undergone a Fontan operation. This approach to endocardial pacemaker implantation is potentially of considerable value in patients who do not have transvenous access to the right ventricle.
Blackburn et al. (1993) studied this question.
