Background:

Fractional flow reserve (FFR) is a proven technology for guiding percutaneous coronary intervention, but it is not reimbursed despite the fact that it frequently allows to defer revascularization. Our goal was to determine the economic benefit of FFR on intermediate lesions, as well as the clinical endpoints at 1 year follow up.

Methods:

Observational prospective study that included consecutive patients with intermediate lesions evaluated with FFR between April 2013 and March 2016. For the economic analysis we evaluated the specific resources used during the procedure. Clinical endpoints including cardiovascular death, target lesion revascularization and acute myocardial infarction, were followed up over a one-year period.

Results:

FFR was performed on 222 lesions in 151 consecutive patients. FFR was positive in 26.1% of the assessed lesions. The estimated total cost using FFR was US$ 891,290.08 while cost estimate without FFR was US$ 1,557,352, meaning 43% in cost savings. There was one cardiovascular death and two readmissions during follow up in the positive FFR group.

Conclusions:

FFR guided revascularization on intermediate coronary lesions resulted in an economic benefit by reducing overall costs without harming clinical outcomes.
