Interference Between Pressure-Wire and Deployed Coronary Stents: Insights from a Bench Test
Highlights
- • Our bench test evaluated interference between pressure-wires and side-branch stents.
- • Objective assessment was achieved using a fiberscope placed in the bifurcation model.
- • Difference of the interference was highly dependent on the types of pressure-wire.
- • Causative mechanism of the interference was also demonstrated.
Abstract
Background
While several complications related to pressure-wire (PW) have been reported, mechanistic justification has not always been offered. Furthermore, interference between a PW and a protruding side-branch stent has not been previously reported. The purpose of this study was to evaluate interference between PW-pullback from a main-branch with a protruded ostial stent deployed in a side-branch.
