The technique stabilizes the guiding catheter by positioning a balloon in the aorta, thereby defining the aorto‐ostial landing zone (AOLZ) for precise stent placement. Post‐procedural CCTA were systematically performed to assess the positioning of the stent. The primary outcome was technical success including optimal stent placement within the AOLZ and proximal anatomy‐dependent geographic miss.ResultsThe primary outcome was achieved in 83% of cases, with 66% showing complete AOLZ coverage and 17% classified as a proximal anatomy‐dependent geographic miss. Proximal procedure‐dependent geographic miss occurred in only 17% of cases, with limited stent protrusion into the aorta (2.3 and 2.9 mm).ConclusionsThe floating balloon technique demonstrated feasibility and precision in optimizing stent placement in AOL, as assessed by CCTA. It offers a promising, cost‐effective, and practical alternative to other techniques. Larger studies are required to confirm its efficacy and long‐term benefits. 10.1002/ccd.31449 http://onlinelibrary.wiley.com/termsAndConditions#vor |
