Dynamic Change of Coronary Artery Geometry After Bioadaptor Implantation: A Single-blind Randomized Controlled Trial

Circ Cardiovasc IntervPublished

  • Single-blind Randomized Controlled Trial
  • vessel segments randomized

Authors' conclusion

The novel bioadaptor technology demonstrated favorable restoration of 3-dimensional dynamic geometry of the treated vessel segment 12 months after implantation, in comparison with traditional DES. These initial mechanistic findings suggest a potential explanation for the favorable clinical outcomes observed in prior trials, and our analytical approach may offer new insights to guide future vascular implant designs and evaluations.

Study context

Population
Patients undergoing percutaneous coronary intervention, with coronary computed tomography angiography at 1 and 12 months post-implantationvessel segments in 48 patients randomized
Participants
48 patients
Comparison
bioadaptor vs DES
  • bioadaptorn = 24
  • DESn = 24
Primary endpoint
Change in dynamic vessel geometry (curvature flexibility, torsion flexibility, path flexibility) of the treated segment during the cardiac cycle
Follow-up
1 to 12 months

Primary result

As reported in the abstract

  • Torsion flexibility: significant within-group improvement from 1 to 12 months with bioadaptor; no significant change with DES
  • Curvature and path flexibility increased numerically with bioadaptor; within-group differences not statistically significant
  • Between-group: increase in path flexibility significantly greater with the bioadaptor than with DES
  • within-group paired analyses
