Alternative left ventricular pacing approaches for an optimal cardiac resynchronization therapy

Cardiac resynchronization therapy (CRT) improves mortality, morbidity and quality of life in selected heart failure patients with severe left ventricular ejection fraction impairment. However, between 20% and 40% of device recipients do not benefit clinically from CRT. Indeed, some anatomical and technical difficulties are related to the coronary venous implantation site via the coronary sinus (CS). Additionally, electrical constraints have been described and CS does not always correspond to the optimal LV lead position.
