Abstract
BACKGROUND:
The prognostic value of poststent fractional flow reserve (FFR) has not been clearly defined in patients with drug-eluting stent (DES) implantation. This study sought to evaluate the association between FFR and clinical outcomes after DES implantation with intravascular ultrasound (IVUS) assistance.
METHODS:
A total of 115 lesions (107 patients) with FFR measurement after IVUS-assisted DES implantation were enrolled. Poststent angiographic and IVUS parameters were compared with FFR values. Clinical outcomes were assessed by target vessel failure (TVF), defined as a composite of target vessel revascularization, death, or non-fatal myocardial infarction attributed to the target vessel.
RESULTS:
Mean poststent FFR was 0.92 ± 0.04. Minimal stent area by IVUS had a positive correlation with poststent FFR (r = 0.36; P<.01). Poststent FFR ≥0.89 was a physiologic cut-off value for 1-year TVF-free survival. The best cut-off value of minimal stent area to define poststent FFR ≥0.89 was >5.4 mm² (sensitivity, 63.2%; specificity, 90.0%). At 3-year follow-up, lesions with poststent FFR ≥0.89 had a better TVF-free survival rate than those with poststent FFR <0.89 (89.3% vs 61.1%, P =.03).
CONCLUSION:
Poststent FFR can be a useful predictor for long-term clinical outcomes after DES implantation and relevant to IVUS minimal stent area.
