Clinical Advantages

Each year, more than two million people worldwide undergo coronary stenting, a procedure that restores blood flow to a blocked coronary artery. While clinical results of stenting procedures have steadily improved, approximately 30% of individuals undergoing these procedures experience a significant adverse event.

Stenting has traditionally been guided by X-ray angiography, which identifies the general location of the luminal blockage but cannot reveal the health of the vessel wall. Physicians are increasingly recognizing the limitations of relying on angiography alone and are turning to more advanced imaging solutions to optimize not only their stenting strategy, but also the overall care of their interventional cardiology patients.

There is a growing awareness of the need to more effectively characterize the vessel by assessing not only its structure (by way of angiography and IVUS) but also its composition. The TVC Imaging System ™ was developed to meet this need.

Revealing What You Need to Know

By obtaining a composite view of both vessel structure and composition, the TVC Imaging System provides interventional cardiologists with comprehensive information necessary to optimize clinical decision-making and support treatment strategies.

The TVC System can help:

• Identify which patients are vulnerable to worsening coronary artery disease by assessing not only the degree of stenosis but also the presence of lipid core plaques (LCP) of interest.
• Guide stent placement to potentially minimize the risk of distal embolization.
• Increase diagnostic efficiency and reduce overall procedural cost.
