This clinical vignette discusses the application of fractional flow reserve in evaluating serial coronary artery stenoses.
FFR may guide serial stenosis evaluation in unstable angina; leaves open prospective validation beyond vignettes.
A man in his 70s who had undergone prior coronary artery bypass graft surgery presents with unstable angina; disease in the obtuse marginal branch appears stable, but there is worsening of disease in the ramus branch, where 2 serial lesions are identified. What would you do next?
