Clinical outcomes after intravascular ultrasound and fractional flow reserve assessment of intermediate coronary lesions. Propensity score matching of large cohorts from two institutions with a differential approach

Resultado clave

IVUS leads to a higher rate of revascularisation in intermediate coronary lesions but does not influence clinical outcomes compared to FFR assessment.

PICO estructurado

Does IVUS compared to FFR affect clinical outcomes and revascularization rates in patients with intermediate coronary lesions?

Clinical outcomes and degree of revascularisation

Both IVUS and FFR are safe for deferring revascularization in intermediate coronary lesions, though IVUS leads to a higher rate of revascularization without altering overall clinical outcomes.

Resumen

IVUS and FFR may be safely used to defer revascularisation of intermediate lesions. IVUS induces a higher degree of revascularisation but much lower than previously reported and does not affect the clinical outcome.
