Transforming Interventional Procedures with Augmented Reality

Spun out of Washington University, SentiAR developed the first 3D visualization platform using real-time holography of the patient’s anatomy and catheter location, “floating” over the patients, with a goal to provide the clinician and patient a faster, safer delivery of care. Their mission is to transform the experience for both patient and clinician in interventional procedures.

The visualization is fully controllable “hands-free” by the clinician, providing an ergonomic breakthrough for the treatment and analysis of cardiac arrhythmias within an interventional catheter lab environment.

Why We Invested

SentiAR is co-founded by a renowned electrophysiologist, a professor of biomedical engineering, and a former biophysics scientist at Boeing. With positive feedback from electrophysiologists, the product has potential in numerous applications and is the only intraprocedural augmented reality solution for the heart.

Worldwide, over 40 million people suffer from cardiac arrhythmias. Treatment options, other than specialized drugs with potentially serious side effects, are very limited, and the only known curative solution is a cardiac ablation procedure. That procedure is currently pursued annually by only about 2-3% of the population suffering from cardiac arrhythmias (1,000,000 patients treated annually) due to its complex nature and low success rates. The current first procedure success rate, where a patient does not have to come back for a second procedure within the first year, is only around 50%.

Cardiac ablation procedure volume is on the rise due to an aging population and improved diagnosis, projected to be at 1.5 million procedures annually on a global basis within five years, with 250-300K of these procedures performed to address earlier failures.



In May 2023, SentiAR announced a major milestone. Dr. Greg Michaud from Mass General Brigham Hospital performed the world’s first clinical case with the SentiAR Holographic Guidance Platform in the PARADIGM study.


“The VCapital team not only led the investment but were very supportive by sharing their insights and diligence. It has been great working with VCapital and their vast network, both of which are extremely valuable.”
