Does DynamX bioadaptor implantation using the culotte technique achieve procedural success and favorable IVUS outcomes in patients undergoing bifurcation percutaneous coronary intervention?
The use of the DynamX bioadaptor in complex bifurcation lesions using the culotte technique is feasible and associated with excellent acute procedural success and favorable IVUS expansion metrics.
Abstract 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.
Hoang et al. (Tue,) conducted a observational in Coronary bifurcation lesions (n=13). DynamX bioadaptor (culotte technique) was evaluated on Technical success (successful deployment of both bioadaptor stents with < 30% residual stenosis and TIMI grade flow 3 in both branches). The DynamX bioadaptor achieved 100% technical and procedural success in patients undergoing complex bifurcation percutaneous coronary intervention using the culotte technique.
