Usefulness of electroanatomical mapping during transseptal endocardial left ventricular lead implantation
Key result
Electroanatomical mapping successfully guided transseptal endocardial LV lead implantation in all 4 patients, maintaining stable electrical parameters over 18.3 months without complications.
Why the study?
Does electroanatomical mapping facilitate successful transseptal endocardial left ventricular lead implantation in CRT patients with failed standard approaches?

Structured PICO
Does electroanatomical mapping facilitate successful transseptal endocardial left ventricular lead implantation in CRT patients with failed standard approaches?
P
Population
4 patients requiring cardiac resynchronization therapy (CRT) who had unsuccessful transvenous implantation or epicardial LV lead dysfunction
I
Intervention
Transseptal endocardial left ventricular lead implantation guided by electroanatomical mapping
O
Outcome
Successful implantation with stable electrical parameters (lead impedance and pacing threshold)surrogate
Electroanatomical mapping is a feasible and useful tool to guide transseptal endocardial LV lead implantation and identify optimal lead positions in CRT patients when standard approaches fail.
Cite This Study
Kutyifa et al. (2011) conducted a case report in Unsuccessful transvenous implantation or epicardial LV lead dysfunction in CRT patients (n=4). Electroanatomical mapping during transseptal endocardial left ventricular lead implantation was evaluated on Successful implantation and stable electrical parameters. Electroanatomical mapping successfully guided transseptal endocardial LV lead implantation in all 4 patients, maintaining stable electrical parameters over 18.3 months without complications.
