Why the study?

Does an IVUS-guided facilitated transfemoral strategy improve procedural outcomes compared to angiography guidance in patients with severe iliofemoral artery disease undergoing TAVI?

Key Points

To evaluate whether an intravascular ultrasound-guided facilitated transfemoral access strategy improves procedural outcomes compared to angiography guidance in patients undergoing TAVI with unfavorable iliofemoral anatomy, and to compare vessel sizing across imaging modalities.
Assessed patients with severe iliofemoral artery disease considered unfavorable for transfemoral TAVI based on preprocedural computed tomography angiography (CTA) within the FIVUS-TAVI registry.
Compared procedural outcomes between an intravascular ultrasound (IVUS)-guided facilitated access approach and standard angiography guidance.
Evaluated differences in iliofemoral vessel sizing across preprocedural CTA, fluoroscopic angiography, and IVUS.
Investigated procedural success and clinical endpoints comparing IVUS-guided facilitated access against standard fluoroscopy-guided transfemoral access.
Identified comparative differences in iliofemoral vessel caliber measurements across preprocedural CTA, invasive angiography, and IVUS to optimize sheath selection.
