Enhanced stent visualization systems during PCI: A case series and review of literature.

Enhanced stent visualization systems increase the amount and quality of information during percutaneous coronary interventions. When compared to imaging techniques such as intravascular ultrasound and optical coherence tomography, enhanced stent visualization systems are easy-to-use, as well as time and cost saving. They are useful during stent implantation, overlap, assessment of integrity, and expansion. We review the available data regarding enhanced stent visualization systems and we report 5 cases showing their current applications during percutaneous coronary interventions. <Learning objective: Enhanced stent visualization (ESV) systems are helpful especially during complex percutaneous coronary interventions (PCI). In everyday clinical practice, ESV systems can be used both along with and instead of intracoronary imaging systems. The present case series show the main current applications of ESV systems during complex PCI cases with a brief review of the available data.>.
