Trial Outcomes & Findings for Apogee, A HeartWare HVAD Destination Product Surveillance Registry (PSR) Platform (NCT NCT03697980)

NCT ID: NCT03697980

Last Updated: 2023-12-04

Results Overview

Freedom from event is the probability (expressed as a percent of 100) the participant did not have a major adverse event during 12 months post implant via the Kaplan-Meier method. Participants that did not have a major adverse event were censored at the time of last follow-up in Apogee or their end of study at 12 months post implant, whichever occurred first. Major adverse events are defined to be occurrence of infection, bleeding, device malfunction, CT confirmed stroke, or death. Infection, bleeding, device malfunction and CT confirmed stroke were categorized via Intermacs Version 5.0. Events occurring during the implant procedure were excluded.

HVAD
HeartWare Ventricular Assist Device: The HVAD is an implantable centrifugal rotary blood pump that is implanted in the pericardial space and is designed to provide up to 10 L/min of blood flow from the left ventricular to the aorta. The HVAD System is comprised of three major components: the HVAD (pump) with inflow and outflow conduits, a Controller (microprocessor unit that controls the operation of the HVAD), and power sources (AC and DC power adapters that provide power to the Controller and implanted HVAD).

PRIMARY outcome

Timeframe: Implant to 12 months

Population: All implanted participants are included.

Freedom from event is the probability (expressed as a percent of 100) the participant did not have a major adverse event during 12 months post implant via the Kaplan-Meier method. Participants that did not have a major adverse event were censored at the time of last follow-up in Apogee or their end of study at 12 months post implant, whichever occurred first.
