Key result

Folded balloons enhance final stent expansion at lower pressures versus rubber balloons in simulations.

Population

Finite element model of a diseased artery with 40% stenosis and stenotic plaque

Discussion

Member takes

Implication

Modeling parameters critically influence stent FE simulations; extends computational methods but leaves clinical translation open.

Structured PICO

Population

Finite element model of a diseased artery with 40% stenosis (inner diameter 4 mm, wall thickness 1 mm, length 20 mm) and stenotic plaque

Intervention

Finite element simulation of Xience stent deployment using a folded balloon and partially constrained artery

Comparator

Simulation using a cylindrical rubber balloon and free or fully constrained arteries

Outcome

Biomechanical behavior of the stent-artery system (stent expansion, recoiling effect, and stress distribution)surrogate

Finite element simulations demonstrate that using a folded balloon and a three-layer anisotropic artery model provides a more accurate representation of stent deployment biomechanics.

Limitations

The folded balloon model lacks interaction with the catheter, which led to an overestimation of the dogboning effect during the initial expansion.
The folded balloon model lacks interaction with the catheter, leading to an overestimation of the dog-boning effect during early expansion.

Schiavone et al. (2015) studied Coronary stenosis (simulated). Folded balloon, artery constraints, and constitutive models vs. Rubber balloon, different constraints and models was evaluated on Stent expansion and stress distribution. Finite element simulations demonstrated that folded balloons produce sustained stent expansion under lower pressure compared to rubber balloons, leading to increased stress levels and enhanced final expansion.
