BACKGROUND: The DynamX bioadaptor is a novel coronary implant with three helical strands that unlock and separate to provide dynamic vessel support restoring natural vessel function. Evidence in complex bifurcation lesions requiring planned two-stent strategies is limited. This analysis evaluated the feasibility and short-term outcomes of culotte bioadaptor implantation using intravascular ultrasound (IVUS).
METHODS: Thirteen consecutive patients underwent bifurcation percutaneous coronary intervention using culotte technique with DynamX bioadaptor between February and October 2025. All procedures followed a standardized culotte protocol with lesion preparation, proximal optimization technique, rewiring, and final kissing balloon inflation, with IVUS used to assess bioadaptor expansion, apposition, and structural integrity.
RESULTS: Technical and procedural success was achieved in all patients (100%), with successful rewiring through bioadaptor struts in all attempts (26 of 26, 100%). IVUS demonstrated satisfactory expansion: main branch ostial expansion 94.9% ± 10.6%, side branch ostial expansion 90.2% ± 17.5%, and proximal expansion ratio 0.95 ± 0.16. No strut fractures or malapposition occurred.
CONCLUSIONS: Early experience with bioadaptor implantation in culotte bifurcation stenting demonstrates feasibility, with favorable acute IVUS findings in selected patients.
