Long-term Variations of FFR and iFR After Transcatheter Aortic Valve Implantation

R Scarsini, M Lunardi, F Ribichini et al. Keywords: FFR; iFR; severe AS; post TAVI

ABSTRACT

Long-term variations of fractional flow reserve (FFR) and instantaneous wave-free-ratio (iFR) after transcatheter aortic valve implantation (TAVI) have not been previously assessed. A total of 23 coronary lesions in 14 patients with aortic stenosis (AS) underwent physiology assessment at baseline, immediately after TAVI and at 14(7-29) months of follow-up. The angiographic severity of the lesions did not progress at follow-up (54[45-64] vs 54[49-63], p = .53). Overall, FFR (0.87[0.85-0.92] vs 0.88[0.82-0.92], p = .45) and iFR (0.88[0.85-0.96] vs 0.91[0.86-0.97], p = .30) did not change significantly compared with the baseline. FFR decreased in 3(13%) lesions with abnormal baseline value, whereas it remained stable in lesions with FFR > 0.80. Conversely, iFR did not show a systematic trend at long-term after TAVI. However, iFR demonstrated a higher reclassification rate at follow-up compared with FFR (p = .02). In conclusions, in this exploratory study, only minor variations of coronary physiology indices were observed at long-term after TAVI. Nevertheless, caution should be exercised in the interpretation of borderline FFR and iFR values in severe AS.
