standard BIV
the following group describes the effects of the left ventricular stimulation involving a dipole of two electrodes located inside a suitable vessel branch of the coronary sinus (CS).
Standard BIV pacing modality can be achieved by either a quadripolar electrode implanted in the CS, of which only two poles will be used for cardiac resynchronization therapy, or by a bipolar electrode equipped with just two electrodes.
The latter describes the old technology, requiring a change into typology of generator which has to display an IS-1 connection (due to different distal terminal of the electrode itself), instead of the new one IS-4 connection that has been developed for quadripolar electrodes.

MPP BIV
Such modality of left ventricular stimulation requires a dynamic use of the four electrodes located in the proximal segment of the electrocatheter that allows the recruitment of a vast area of the left ventricle.
It is limited by the presence of scars on left ventricle surface, or phrenic nerve inadvertent stimulation.

Implanted CRT-D devices settings will be programmed based on the best acute hemodynamic response assessed non-invasively

Primary Outcome Measures
Primary Outcome Measures
Outcome Measure |
Measure Description |
Time Frame |
|---|---|---|
|
Acute improvement in cardiac function (1)
Time Frame: 24-48 hours after CRT-D implantation
|
change in dP/dtmax, expressed in mmHg/s, assessed through photoplethysmography.
This assessment represents in a non-invasive fashion, the rise in pressure (P) developed inside left ventricle during contraction over time.
|
24-48 hours after CRT-D implantation
|
|
Acute improvement in cardiac function (2)
Time Frame: 24-48 hours after CRT-D implantation
|
change in global longitudinal strain, assessed through echocardiography.
This assessment elucidates longitudinal shortening of the left ventricle as a percentage (change in length as a proportion to baseline length).
GLS is derived from speckle tracking, and analyzed by post-processing of apical images of the left ventricle.

Outcome Measure |
Measure Description |
Time Frame |
|---|---|---|
|
Delayed response (1)
Time Frame: 3 Months
|
change in GLS.
Participants will investigate whether left ventricular remodeling upon "patient-tailored" biventricular stimulation will behave differentially according to type of stimulation; the total amount of CRT-responder patients will be therefore considered
|
3 Months
|
|
Delayed response (2)
Time Frame: 3 Months
|
change in NYHA class.
Participants will check if functional status will change after optimized biventricular stimulation therapy and will provide clinical data on CRT responders.
