“We introduced ultrasound transit-time flowmetry during the early days of beating heart CABG surgery, and developed flow-based graft patency algorithms together with our collaborator Dr. Bruce Mindich.  These algorithms have withstood the test of time, and are now incorporated in our flowmeter in a manner where flow-based CABG patency assessment may become part of the routine armamentarium of all CABG surgeons.”    Transonic CEO Cor Drost​

CABG Patency Assessment Program & CABG Failure Rates

Early graft failure following Coronary Artery Bypass Graft (CABG) procedures occurs in >3% of grafts and accounts for millions of dollars in readmission and re-operations. The patency of coronary bypass grafts is the heart of CABG surgery. Transonic’s transit-time ultrasound volume flow measurement capability offers cardiac surgeons objective evidence  that the grafts they anastomose are patent.

What does the new Optima 354C Meter Provide?

With unsurpassed accuracy, the new Optima 354C Flowmeter and Coronary flow probes provide immediate, quantitative data to objectively assess the quality of an anastomosis. Utilizing a pressure input and combining that with an innovative waveform analysis algorithm, the new meter offers a novel assessment tool that helps demystify waveform analysis.  Unseen blood flow obstructions can be detected immediately and repaired before closing the patient. This ability to correct otherwise undetectable flow restrictions is an opportunity to improve patient outcomes. Studies have shown that measuring flow intraoperatively reduces early graft failure following CABG surgery. Benefits of this invaluable quantitative tool are:

  • Verify graft patency
  • Reduce readmissions and reoperations
  • Improve patient outcomes

What is the CABG Patency Assessment Program?

Transonic is so confident that our measurement can help hospitals to improve graft patency and contribute to the reduction of unnecessary readmissions for prematurely failed grafts 30 days post-op, that we back up our claim with a Patency Assurance program.

The Transonic CABG Patency Assessment Program demonstrates Transonic’s commitment to partner with our customers to contribute to process improvements and to reduce readmissions following CABG. We will partner with the hospital, train them on using flow measurement and will provide free keys following any failed grafts after a flow measurement has shown that the graft is patent.  

 

How Does the Program Work?CABG Surgery

With a signed Optima 354C Flowmeter Placement Agreement under our CABG Patency Assurance Program, Transonic will credit your hospital for 5 keys:

  • A patient’s set of bypass grafts met Transonic’s patency criteria.
  • Hospital signs 1-year Optima 354C Flowmeter Placement Agreement. 
  • If within 30 days, a post-CABG patient returns to the hospital for an additional unplanned intervention (re-operation or percutaneous procedure) to redo a graft that met CABG patency criteria at the end of surgery. 

We know that this technology works and are willing to take on some of the risk to prove that it does. Partner with us to learn how flow measurements can save your hospital unnecessary and costly reoperations!
