Bypass Grafting and Native Coronary Artery Disease Activity

Bypass Grafting and Native Coronary Artery Disease Activity

Positron emission tomography (PET) with F sodium fluoride (F-NaF) allows for the assessment of microcalcification activity (MA) in a wide variety of cardiovascular conditions, including atherosclerosis. In coronary artery disease, this tracer correlates with progressive disease and allows for the prediction of atherosclerosis progression.  Unlike PETs, computed tomography (CT) allows for the evaluation of an

EuroPCR 2020 | A Trick to Find the Perfect Projection to Treat Ostia or Bifurcation Lesions

The trick is to avoid testing empirically more to the right or to the left, a more caudal or cranial angular, and check what a multislice computed tomography suggests. The increase in coronary computed tomography imaging studies—due to guideline recommendations, practicality, and patient comfort—means that we frequently have these data in the cath lab even

New Technique to Calculate CT-Derived Fractional Flow Reserve: Is It Accurate?

This study describes the accuracy of the new computed tomography (CT) technique to calculate fractional flow reserve (FFR).   Other CT techniques to measure FFR use allometric scaling and assume coronary microvascular resistance. However, instead of assuming these parameters, this new technique calculates them based on coronary and aorta lumen deformation. The accuracy of this

Could CT angiography replace coronary angiography in the short term?

Original Title: CT Angiography for the Prediction of Hemodynamic Significance in Intermediate and Severe Lesions. Head-to-Head Comparison with Quantitative Coronary Angiography Using Fractional Flow Reserve as the Reference Standard. Reference: Matthew J. Budoff et al. J Am Coll Cardiol Img. 2016;9(5):559-564.   The aim of this study was to compare the diagnostic accuracy of non-invasive
