The VITAL process helped launch HeartFlow®, a revolutionary technology that helps doctors diagnose and treat heart blockages.

Real benefits for clinicians

VITAL was instru­mental because, orig­i­nally, I thought I’d have to convince my admin­is­tra­tion to adopt HeartFlow®. For me, as one person, it might have been very chal­lenging to make the case for it. 

But to have the backing of VITAL and their support in the pilot made it much easier. VITAL gave us the perfect avenue to put this tech­nology into prac­tice.

Any time we can prevent unnec­es­sary proce­dures, espe­cially inva­sive proce­dures like heart catheter­i­za­tions, that reduces risks for the patient. The asso­ci­ated health care savings also are a plus.”

Improved patient experiences

  • 61% of patients avoided an inva­sive angiogram3
  • Similar revas­cu­lar­iza­tion rates4
  • Zero adverse clin­ical events among patients whose angiogram was canceled5
  • 26% cost reduc­tion compared to usual care testing for patients with suspected coro­nary artery disease6

A VITAL collaboration

Because of VITAL’s collab­o­ra­tion with HeartFlow, Inc. and Allegheny Health Network clin­i­cians, doctors now can have sophis­ti­cated 3-D modeling tools at their finger­tips. HeartFlow® analysis improves the patient expe­ri­ence because it allows them to avoid more inva­sive testing for block­ages. And it’s been shown to signif­i­cantly improve quality of life.1

HeartFlow® uses images from stan­dard coro­nary CT angiograms (cCTAs) to create person­al­ized digital 3-D models of each patient’s coro­nary arteries. Using advanced computer algo­rithms to solve millions of complex equa­tions, the tech­nology deter­mines a frac­tional flow reserve” for all the arteries, which assesses the impact of block­ages on blood flow. 

This infor­ma­tion helps physi­cians decide the best treat­ment for each patient.
