Registry for Quality Assessment With Ultrasound Imaging and TTFM in Cardiac Bypass Surgery (REQUEST)

This study is currently recruiting participants. (see Contacts and Locations)
Verified April 2016 by Medistim ASA
Information provided by (Responsible Party):
Medistim ASA Identifier:
First received: February 17, 2015
Last updated: November 23, 2016
Last verified: April 2016
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: 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: September 2017
Estimated Primary Completion Date: September 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

Study Population
Subject has been scheduled for coronary bypass surgery

Inclusion Criteria:

  • Subject has been scheduled for coronary bypass surgery
  • Subject understands the nature of the procedure and has signed the subject informed consent prior to the procedure
  • Subject has been diagnosed with 2-3 vessel disease

Exclusion Criteria:

  • Subject is scheduled for other surgical procedures during the bypass surgery (valve replacement/repair, carotid endarterectomy, etc.)
