5.1. MSP STUDY
Sorin conducted an international, multi-center, randomized clinical trial of its cardiac
resynchronization therapy system. Investigators attempted to implant study devices in 190
patients. A total of 182 patients received study devices and had an exposure of over 165
device years. Of those patients, 19 received OVATIO CRT-D, 160 received ALTO 2 MSP,
and 3 received ALTO MSP. The clinical data collected on ALTO MSP, ALTO 2 MSP and
OVATIO CRT-D are applicable to INTENSIA SonR CRT-D 184. The table below summarizes
the adverse events observed for the CRT-D system. No deaths were related to the system.
