Trang 2Benefits of Cardiac Resynchronization Therapy
CRT benefits heart failure patients with a wide QRS and low LVEF
Compared to RV (right ventricular) only pacing, CRT:
Improves EF, NYHA class and 6 MWT results1
Decreases hospitalizations1,4
Reduces the risk of death2
Compared to optimal pharmacological therapy, CRT:
Reduces rates of all-cause, cardiac, and HF hospitalization3
Quadripolar CRT Systems have represented a new opportunity to
improve CRT implant success and avoid common CRT complications

Electrical Mechanical Hemodynamic
Methods
This study evaluated the effect of MultiPoint™ Pacing
(MPP™) on the left ventricular (LV) activation pattern
and hemodynamics in the same patient population
A total of 10 patients with non-ischemic cardiomyopathy
underwent an acute pacing protocol that included 2
biventricular (BiV) and up to 9 MPP technology
interventions
Results
Compared with BiV, MPP technology significantly increased
LV dP/dtmax (30 ±13% vs 25 ±11%, P = 0.041); reduced
QRS duration (22 ±11% vs 11 ±11%, P = 0.01) and
decreased total endocardial activation time (25 ±15% vs 10
± 20%, P= 0.01).
MPP technology also captured significantly greater LV mass
during the first 25 ms and first 50s of pacing, suggesting
faster wavefront propagation throughout the LV
MPP technology improved acute hemodynamic parameters,
QRS duration and activation patterns in comparison to BiV

Trang 13MultiPoint™ Pacing 12-month
Methods
44 consecutive patients were randomized to receive
pressure-volume (PV) loop optimized MPP™
technology or Conventional CRT (CONV) at a single
center in Italy
The primary endpoint was the change in end systolic
volume (ESV) and ejection fraction (EF) from baseline
to 12 months in the MPP technology group vs the
CONV group
Response to CRT was defined as alive status and ≥
15% decrease in ESV relative to the baseline
Results
ESV and EF increase relative to baseline were
significantly greater with MPP technology than with
CONV (ESV: median –25% vs median –18%, P =
0.03; EF: median +15% vs median +5%, P < 0.001)
At 12 months, 76% (16/21) of patients in MPP
technology group were classified as CRT responders
compared with 57% (12/21) in the BiV group
The CRT response rate in the MPP technology group
remained consistent at 76% from 3-month to 12-month
follow-up
PV loop-guided MPP technology resulted in greater LV
reverse remodeling and increased LV function at 12
months compared with similarly optimized

Benefits of Switching
MPP™ Technology
Methods
from Conventional CRT to
The aim of this study was to evaluate if patients
receiving conventional CRT (CONV) would receive
additional benefit by switching CRT programming to
MPP technology (n = 8)
Patients implanted with a CRT 12 months post implant
had their CRT programming switched to MPP
technology after echo and NYHA class assessment
and classified as responders (6/8) or non-responders
(2/8) based on echo comparison to baseline
Responder was defined as ESV ≥15% relative to
baseline
Results
The two non-responders to CONV became responde
with MPP technology with reduction in ESV and
improvement in EF relative to the 12 month exam
The remaining 6 patients classified as responders to
CONV also experienced additional reduction in ESV
and improvements in EF
The study results suggest that activating MPP
technology may be a potential strategy to
convert non- responders to responders or
further improve response in patients already
responding to conventional therapy
