Superior atrial transseptal LV endocardial lead implantation proves feasible without mitral valve impingement in isolated hearts.
Demonstrates the feasibility of a superior atrial transseptal approach for LV endocardial lead implantation in an isolated heart model.

Supports further preclinical exploration of transseptal LV leads; hypothesis-generating and not ready for clinical translation.
KEY TEACHING POINTS•Implantation of an LV endocardial lead is feasible using a superior atrial transseptal approach.•A catheter-based delivery system with RF wire can be used to locate and puncture the atrial septum, and subsequently guide/implant an active fixation lead in the LV with minimal steps.•An LV endocardial lead can be placed without impingement of the mitral valve.

Yang et al. (2015) studied this question. Atrial transseptal left ventricular endocardial lead implantation was evaluated on Feasibility of implantation. Implantation of a left ventricular endocardial lead using a superior atrial transseptal approach is feasible without impingement of the mitral valve in an isolated heart model.
