Summary
The floating-wire technique effectively reduces coronary stent movement during percutaneous coronary intervention, improving stent placement accuracy. This safe and simple method is easily applicable in cardiac catheterization labs.
Area of Science:
- Interventional Cardiology
- Medical Devices
Background:
- Coronary stent placement can be challenging due to excessive stent motion within the artery.
- Accurate stent positioning is crucial for successful percutaneous coronary intervention outcomes.
Purpose of the Study:
- To evaluate the efficacy of the floating-wire technique in minimizing coronary stent movement.
- To determine if this technique improves the accuracy of stent deployment.
Main Methods:
- The floating-wire technique was employed during percutaneous coronary intervention when excessive stent movement was observed.
- Postprocedural angiograms were analyzed to quantify stent motion before and after applying the technique.
- Two independent operators assessed stent delivery system motion relative to the coronary artery.
Main Results:
- The floating-wire technique was necessary in 19 patients, with no procedural complications reported.
- A significant reduction in stent motion was observed, decreasing from 4.04 ± 1.25 mm to 1.11 ± 0.81 mm (P<.001).
Conclusions:
- The floating-wire technique is a safe and effective method for reducing stent movement during coronary interventions.
- This technique facilitates accurate stent deployment and can be readily implemented in cardiac catheterization laboratories without special equipment or training.
