Long-term outcome after deferred revascularization due to negative fractional flow reserve in intermediate coronary lesions.

Objectives: The aim was to assess long-term outcome after deferring intervention of coronary lesions with a fractional flow reserve (FFR) value of >0.80 in a real-world patient population and then to identify factors associated with deferred target lesion failure (DTLF).

Background: Deferring coronary interventions of intermediate lesions based on FFR measurement is safe, irrespective of the extent of coronary artery disease.
