TCT-325 Influence of the amount of myocardium subtended by an intermediate coronary artery stenosis on FFR and iFR

Both FFR, iFR and iFRa were inversely correlated with DJS/MLD ratio (respectively, r2=0.52, p< 0.001, r2=0.53, p< 0.001, and r2=0.64, p< 0.001). [...]the δ%iFR was significantly correlated with the DJS/MLD ratio (r2=0.22, p=0.03), suggesting that myocardial resistance cannot be considered...

Zusammenfassung:Both FFR, iFR and iFRa were inversely correlated with DJS/MLD ratio (respectively, r2=0.52, p< 0.001, r2=0.53, p< 0.001, and r2=0.64, p< 0.001). [...]the δ%iFR was significantly correlated with the DJS/MLD ratio (r2=0.22, p=0.03), suggesting that myocardial resistance cannot be considered negligible during the wave-free period particularly in larger territories.
