Information provided by (Responsible Party):
Medistim ASA
  Purpose
The purpose of the registry is to collect information regarding the number and type of coronary artery bypass (CAB) surgical procedure changes that are made based on intraoperative guidance information using transit time flow measurements (TTFM) and ultrasound image capabilities provided with the Medistim device.

Condition Intervention
Coronary Artery Bypass Device: Medistim device

Study Type: Observational [Patient Registry]
Study Design: Observational Model: Other
Time Perspective: Prospective
Target Follow-Up Duration: 2 Weeks
Official Title: Registry for Quality Assessment With Ultrasound Imaging and TTFM in Cardiac Bypass Surgery

Further study details as provided by Medistim ASA:

Primary Outcome Measures:
  • Change in planned surgical procedure [ Time Frame: Day 1 (During Surgery) ]
    Identify how often epiaortic scanning With the Medistim Device, leads to a change in the planned surgical procedure and to identify the reason and the procedure change

  • Procedure adaptions [ Time Frame: Day 1 (During surgery) ]
    Identify the procedure adaptions made by a surgeon when TTFM and/or Medistim ultrasound imaging identify suboptimal graft function


Secondary Outcome Measures:
  • Record number of revisions [ Time Frame: Day 1 (During surgery) ]
    Record how many Cardiac bypass patients experience intraoperative graft revision, the type of revision, and the key identifier motivating the revision

  • Record number of events [ Time Frame: Day 1-14 (During hospitalization) ]
    Record post-surgical major adverse cardiac and cerebral events (MACCE) of all bypass procedure patients entered into the registry and occuring prior to discharge

  • Incidence rate [ Time Frame: 2 years (Throughout the study) ]
    To determine the incidence rate of Serious Adverse Events (SAE) and/or Unanticipated Adverse Events (UAE) throughout the registry


Estimated Enrollment: 1000
Study Start Date: April 2015
Estimated Study Completion Date: December 2017
Estimated Primary Completion Date: December 2017 (Final data collection date for primary outcome measure)
Intervention Details:
    Device: Medistim device
    This registry is intended to document surgical findings, procedural changes, and adverse events occurring prior to discharge
