Closing the gaps in cardiovascular care through innovation and learning.
Cardiovascular disease is still the leading cause of death worldwide. Too often, the distance between what is possible and what a patient receives comes down to the tools clinicians have and how well they are trained to use them.
CardioSpectra Lab
An independent medical technology company founded by Krtin Singhal, MD. We build technology that helps clinicians see the heart more clearly, from new ways of characterizing cardiac tissue to software that turns measurement into better decisions.
SpectraSim Learning Simulator Suite
Our learning platform. Real patient imaging, 3D anatomy and guideline-based cases let trainees and clinicians practice the decisions of the EP lab, the cath lab and pulmonary embolism care before they meet them at the bedside.
