Multiparametric Cardiac Strain Analysis of Myocardial Viability

Tech ID: T-014564

Background: Assessing left ventricle (LV) cardiac contractile function is a good indicator of overall heart health and is used to determine which patients are good candidates for revascularization surgery. With over 3 million new coronary artery disease patients annually and over 1 million annual revascularization surgeries in the US, there is need for an improved, non-invasive technique to quantitatively assess LV contractile function.

Technology Description: A team led by Dr. Michael Pasque has developed cardiac MRI-based multiparametric strain analysis techniques to provide quantitative assessments of LV contractile function. The patented techniques and Normal Human Strain Database may be used as a screening mechanism to non-invasively assess heart function or to assess cardiac tissue viability to inform revascularization surgeries.

Key Advantages:

  • Uses non-invasive MRI imaging to assess heart function
  • Provides an objective, quantitative measure of LV contractile function
  • Provides localized information
