Unexpected Computed Tomography Derived Fractional Flow Reserve Decline Due to a Short Left Main Coronary Artery and a Wide Bifurcation Angle.

The article explores the impact of bifurcation angles on computed tomography (CT)-derived fractional flow reserve (FFRCT) decline in vessels with no apparent coronary artery disease (CAD). Topics include the correlation between bifurcation angles and FFRCT changes, the identification of optimal cut-off values for bifurcation angles in the left anterior descending (LAD) and left circumflex (LCX) arteries and the significance of vessel length as a predictor of distal FFRCT values.
