ABSTRACT
BACKGROUND AND OBJECTIVES:
Discrepancy between angiographic percent (%) diameter stenosis and fractional flow reserve (FFR) exists in non-left main bifurcation lesions. The aim of this study was to compare angiographic stenosis severity and FFR in jailed ostial left circumflex artery (LCX) lesions after left main (LM)-to-left anterior descending artery (LAD) crossover stenting. SUBJECTS ANDMETHODS:
Twenty-nine (n=29) patients with distal LM or ostial LAD lesions treated by LM-to-LAD crossover stenting were consecutively enrolled. After successful stenting, FFR was measured at the jailed LCX. Additional intervention was performed in lesions with FFR 50%) at the ostial LCX occurred in 59% (17/29) of cases. Among them, only five (29%) lesions had functional significance, and underwent additional procedure. During follow-up, three patients in the deferral group and two patients in the additional intervention group had target lesion revascularization.CONCLUSION:
There was a discrepancy between angiographic percent diameter stenosis and FFR in jailed LCX lesions after LM crossover stenting.
