- •The discordance rate between FFR and iFR was 29.3% in patients with aortic stenosis.
- •Negative discordance (FFR >0.8 and iFR ≤0.89) was dominant in discordant cases.
- •Left anterior descending artery lesions were associated with negative discordance.
- •Peak velocity ≥5.0 m/s was independently associated with negative discordance.
