Overview

Feasibility of bioadaptor culotte in bifurcations shown in small series; leaves open safety, durability, and comparative trials.

Key Points

  • To evaluate the feasibility and short-term outcomes of the DynamX bioadaptor in bifurcation lesions using the culotte technique.
  • Thirteen patients underwent bifurcation percutaneous coronary intervention using the DynamX bioadaptor.
  • Standardized culotte protocol was followed including procedure steps like rewiring and IVUS analysis.
  • Procedures were conducted between February and October 2025.
  • Technical and procedural success achieved in all patients (100%).
  • Rewiring through bioadaptor struts succeeded in all attempts (26 of 26, 100%).
  • IVUS demonstrated main branch ostial expansion of 94.9% ± 10.6% and no strut fractures.

Structured PICO

Does DynamX bioadaptor implantation using the culotte technique achieve procedural success and favorable IVUS outcomes in patients undergoing bifurcation percutaneous coronary intervention?

P
Population
13 patients (mean age 60.3 years, 15.4% female) with symptomatic coronary artery disease and de novo true bifurcation lesions undergoing percutaneous coronary intervention.
I
Intervention
DynamX bioadaptor implantation using the culotte technique with a standardized protocol (lesion preparation, proximal optimization technique, rewiring, and final kissing balloon inflation) and intravascular ultrasound (IVUS) guidance
O
Outcome
Feasibility and short-term outcomes including technical and procedural success, bioadaptor expansion, apposition, and structural integrity assessed by IVUSsurrogate

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.

Limitations

  • Small sample size
  • Single-center design
  • Absence of a control group
  • Short-term follow-up (only acute IVUS outcomes assessed)
  • Left main bifurcations were not included
  • single-center experience
  • selected patients

Cite This Study

Hoang et al. (2026) conducted an 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.
