Occasionally investigations will have determined that a previously implanted stent needs to be optimised to reduce the risk of future complications.
What is stent optimisation?
Optimisation may require further balloon expansion of the stent or calcium modification to allow stent expansion. Usually this is performed using high-definition intravascular imaging (ultrasound or near-infrared imaging of the internal lumen of the artery) in addition to conventional angiography.
Why would you need Stent Optimisation?
Occasionally, a previously implanted stent may need to have further optimisation to reduce the risk of further problems in the future. This may have been discovered due to the presence of new symptoms or even a myocardial infarction (heart attack).
