Speaker:  Alejandra Diaz Sierra, MD  Third-year Cardiology Fellow, Advocate Illinois Masonic Medical Center

Moderator:  Jeffrey Ziffra, MD  Cardiologist, Advocate Heart Institute, Advocate Good Samaritan Hospital

Overview:  This lecture will review contemporary strategies for physiologic coronary lesion assessment comparing CT-derived FFR, angiography - derived FFR (cathworks), and invasive FFR/iFR. This talk will ultimately highlight how these modalities complement one another and inform revascularization decisions in modern practice. 

Objectives:  Upon completion of the activity, the learner should be able to:

    • Compare the principles, evidence-based, and diagnostic performance of the different modalities for physiology evaluation of coronary lesions. 
    • Recognize clinical and anatomic situations in which discordance between non-invasive, angiography-derived, and invasive physiologic measurements is most likely to occur and identify strategies to resolve these discrepancies. 
    • Summarize key randomized trials and major registries evaluating the different modalities, including their diagnostic accuracy, clinical outcomes, and impact on downstream testing and revascularization.
