Trial Outcomes & Findings for Assess Safety and Probable Benefit of the EXCOR® Pediatric Ventricular Assist Device (NCT NCT00583661)

NCT ID: NCT00583661

Last Updated: 2013-03-15

Results Overview

The serious adverse event rate was calculated by totaling the number of serious adverse events all subjects experienced during device support (from implant to explant, an average of 58 days) divided by the total support time (in days) for all subjects. The serious adverse event rates were calculated separately for each primary study cohort.

PRIMARY outcome

Timeframe: Participants were followed while on device support, an average of 58 days

Population: All 48 participants were included in the analysis. Adverse Events for each participant was counted and the total number of events was divided by the total time the Cohort's subjects were supported on device. A 95% Poisson confidence interval was calculated around the point estimates.

The serious adverse event rate was calculated by totaling the number of serious adverse events all subjects experienced during device support (from implant to explant, an average of 58 days) divided by the total support time (in days) for all subjects. The serious adverse event rates were calculated separately for each primary study cohort.

PRIMARY outcome

Timeframe: Participants were followed while on device support, an average of 58 days

Population: All subjects implanted with the device were included in this analysis.

Efficacy of the EXCOR® Pediatric was estimated by showing survival of all participants who were supported by the device.
