Abstract
This case describes the assessment of FFR in the case of tandem intermediate lesions in the proximal and mid LAD. Hyperemia was induced with intravenous (IV) infusion of Adenosine, which allows pullback measurements. First, with the wire placed distal in the vessel, FFR provides information on whether the sum of the two stenoses causes ischemia. Thereafter, during pullback, the most severe stenosis can be identified as the most relevant pressure drop. Finally, a re-evaluation of FFR is important after PCI: after the first stenosis is treated, the degree of hyperemia achievable will be larger, thus unmasking the relevance of the second one.
