The global market for diagnostic and guided interventional cardiology products is expected to reach $4.8bn by 2021, and is driven in large part by the rising elderly population and increasing burden of cardiovascular disease (CVD). Meddevicetracker expects that intracardiac echocardiography (ICE), guide wire-based intravascular stenosis assessment (FFR) and optical coherence tomography (OCT) systems will drive overall market growth, given their high demand, which is supported by clinical evidence needed to bring cost savings and improved outcomes. Physicians' preference for using noninvasive and minimally invasive diagnostic techniques in cases where results are inconclusive is also changing the landscape of innovation. In this feature, we'll take a closer look at the overall market and its regional perspective, the competitive landscape of the three fastest-growing segments ICE, FFR and OCT, and the latest emerging technologies, as well as provide insight into what physicians think of these technologies.
