A trans-lesional fractional flow reserve gradient >0.13 derived from coronary CT potentially reduces invasive coronary angiography by 32.2% (p<0.001) and improves the revascularization to ICA ratio.
Observational
Does trans-lesional fractional flow reserve gradient derived from coronary CT improve prediction of early revascularization and efficiency of catheter laboratory utilization in patients with stable coronary artery disease?
Trans-lesional FFR gradient derived from coronary CT has the potential to reduce unnecessary invasive coronary angiographies and improve cath lab efficiency in patients with stable CAD.
Absolute Event Rate: 73.1% vs 65.2%
p-value: p=< 0.001
BACKGROUND: ) in guiding downstream testing in patients with stable coronary artery disease (CAD) is unknown. OBJECTIVES: in predicting early revascularization and improving efficiency of catheter laboratory utilization. MATERIALS: across visible stenosis. RESULTS: >0.13, would potentially reduce ICA by 32.2% (1638-1110, p < 0.001) and improve the revascularization to ICA ratio from 65.2% to 73.1%. CONCLUSIONS: has the potential to aid decision-making for ICA referral and improve efficiency of catheter laboratory utilization.
Takagi et al. (Thu,) conducted a observational in stable coronary artery disease (CAD). Trans-lesional fractional flow reserve gradient derived from coronary CT was evaluated on invasive coronary angiography (ICA) reduction and revascularization to ICA ratio (p=< 0.001). A trans-lesional fractional flow reserve gradient >0.13 derived from coronary CT potentially reduces invasive coronary angiography by 32.2% (p<0.001) and improves the revascularization to ICA ratio.
