Fractional flow reserve evaluation in patients considered for transfemoral transcatheter aortic valve implantation: a case series


Stähli, Barbara E; Maier, Willibald; Corti, Roberto; Lüscher, Thomas F; Altwegg, Lukas A (2012). Fractional flow reserve evaluation in patients considered for transfemoral transcatheter aortic valve implantation: a case series. Cardiology, 123(4):234-239.

Abstract

OBJECTIVES: Transcatheter aortic valve implantation (TAVI) has become an established therapy for severe aortic stenosis (AS) in high-risk elderly individuals. Concomitant coronary artery disease (CAD) is frequently encountered in this patient population and may have an impact on outcomes. Hence, in patients with both severe AS and CAD, a bespoke therapy of both AS and/or CAD appears mandatory.
METHODS: We report a series of 5 patients with severe AS and concomitant CAD considered for TAVI who underwent fractional flow reserve (FFR) for hemodynamic assessment of coronary lesions.
RESULTS: In 3 patients, a 2-staged procedure was undertaken with FFR measurements at the time of invasive assessment and TAVI thereafter. In the remaining 2 patients, FFR measurements were performed immediately prior to the TAVI procedure with deferral of percutaneous coronary intervention (PCI) in one and ad hoc PCI in the other patient. All 5 patients had uneventful FFR measurements and procedural TAVI outcomes. One patient with a staged approach noted a significant improvement in symptoms already after PCI.
CONCLUSIONS: FFR provides an effective and safe strategy to assess hemodynamic significance of coronary lesions in patients with severe AS and concomitant CAD considered for TAVI.

TrendTerms

TrendTerms displays relevant terms of the abstract of this publication and related documents on a map. The terms and their relations were extracted from ZORA using word statistics. Their timelines are taken from ZORA as well. The bubble size of a term is proportional to the number of documents where the term occurs. Red, orange, yellow and green colors are used for terms that occur in the current document; red indicates high interlinkedness of a term with other terms, orange, yellow and green decreasing interlinkedness. Blue is used for terms that have a relation with the terms in this document, but occur in other documents.
You can navigate and zoom the map. Mouse-hovering a term displays its timeline, clicking it yields the associated documents.
