Key result
Direct left ventricular endocardial pacing was successfully implanted in all 14 patients, with 13 patients improving by at least one NYHA class and experiencing improved left ventricle ejection fraction.
Why the study?
Does direct left ventricular endocardial pacing improve clinical outcomes in patients with heart failure and failed resynchronization via coronary sinus?

Does direct left ventricular endocardial pacing improve clinical outcomes in patients with heart failure and failed resynchronization via coronary sinus?
Direct left ventricular endocardial pacing via a transseptal approach is a feasible and clinically beneficial alternative for cardiac resynchronization therapy when the traditional coronary sinus approach fails.
Moriña‐Vázquez et al. (2013) conducted an observational in Heart failure and left bundle-branch block with failed resynchronization via coronary sinus (n=14). Direct left ventricular endocardial pacing was evaluated on Successful implantation, New York Heart Association class improvement, and left ventricle ejection fraction improvement. Direct left ventricular endocardial pacing was successfully implanted in all 14 patients, with 13 patients improving by at least one NYHA class and experiencing improved left ventricle ejection fraction.
