January 4, 2017 — A new ground-breaking technology that allows evaluation of cardiac valves using holograms was demonstrated at the TedMed 2016 conference in December, posited as the next level of cardiac hemodynamic evaluation. The technology, developed in collaboration with Hitachi and others, was presented by Partho Sengupta, M.D., director of cardiac ultrasound research and core lab and an associate professor of medicine in cardiology at Mount Sinai’s Zena and Michael A. Wiener Cardiovascular Institute and the Marie-Josée and Henry R. Kravis Center for Cardiovascular Health.
The presentation centered around Sengupta’s focus on discovering advanced visualization technologies to evaluate valvular form and function and how it is linked to the cardiac flow geometry. Some of his past work has been with particle image velocimetry (PIV) to demonstrate the valvular flow with vector information. He shared how he is now also using ultrasound to provide the vector information to evaluate this same flow geometry. He presented examples of PIV and Hitachi’s Vector Flow Mapping (VFM) analysis results side by side to illustrate the validity of ultrasound as a tool for vector mapping.
As a look into the future, Sengupta then demonstrated how holograms will play a part in valvular and other cardiac diagnosis by showing an example of a mitral valve hologram.
