Cardiac resynchronization is a recommended therapy for patients with advanced heart failure, under optimized medical treatment with reduced left ventricular ejection fraction and prolonged QRS, nevertheless, still 30% of the population do not respond to standard biventricular implantation. Non-response can be explained by a combination of factors including sub-optimal patient selection, placement of the pacing lead over a zone of slow conduction, insufficient correction of mechanical dyssynchrony including sub-optimal lead implantation. Few data distinguish true non-responders from patients in which effective resynchronization was not delivered through standard biventricular implantation. Triple-site cardiac resynchronization pacing (stimulation at three ventricular sites) has been proposed to improve synchrony and thus the response rate in (Cardiac Resynchronisation Therapy) CRT recipients.

TriV pacing is superior to standard BiV pacing in reversing ventricular modeling as demonstrated by Echo LVESV at 12 months in pts. with non LBBB without increasing the risk of serious events at 30 days.
