Visualisation Enhancement Tool
has potential to ease stent deployment and reduce the need for additional interventional
Visualisation Enhancement Tool. Designed as an interventional tool to improve the visualisation of stents in the coronary arteries, StentBoost provides an almost instant view of a newly placed stent and measures its deployment while the catheter is still in place. Additionally, it enables interventional cardiologists to take any corrective action while the patient is still in the angiography room. The images obtained can be archived, shared with colleagues and viewed remotely in Windows based formats. A study conducted by Dr J.J. Koolen and co-researchers at the Catharina Hospital in Eindhoven, The Netherlands, evaluated the recently introduced image-enhancing tool. The aim of the study was to quantitatively assess the improvement in stent visibility obtained with the tool and compare the images with those obtained with Intravascular ultrasound (IVUS)*, a technique considered to be the 'gold standard'for evaluating stent implantation. Four independent observers assessed stent visibility, and the results indicated that the tool effectively enhanced stent visibility in most cases and showed a good correlation with IVUS. Furthermore, other radiopaque objects, e.g. calcified coronary plaque, became more visible. The visualisation enhancement tool was found to be a "cheap, simple and quick method for improving the visibility of stents during implantation, and has the potential for more extensive application."* * Koolen JJ, van het Veer M, Hanekamp CEE.
