About Us

DASI Simulations performs advanced individualized computational predictive modeling powered by artificial intelligence and computer vision to better plan for improved patient outcomes and reduced costs associated with Structural Heart Disease.

Founder's Story

By fortunate circumstances, I mean meeting Dr. Lakshmi Prasad Dasi, an associate professor of biomedical engineering and surgery at The Ohio State University (OSU), at a trade show in 2018. Dr. Dasi and his team walked by my booth where I was marketing mock vessels of the heart and aortic system. Dr. Dasi's students wore OSU shirts and carried OSU backpacks.

“I am all things Buckeye,” I said. My daughter graduated from OSU in 2018, so I felt an immediate connection. I engaged Dr. Dasi, demonstrating how he could use my silicon models in his experiments.

Dr. Dasi had been using the silicone products in his lab for about a year when I visited to understand better how the silicone models fit into his work. He pulled up a raw PowerPoint of the technology he had developed using the vessels I sold to him and then he asked, “Do you know anyone who might want to start a company with me?”

For me, helping improve outcomes for patients with heart disease felt personal. My father passed away at age 67 after two unsuccessful heart surgeries. There was something inside of me wanting to do this. It was like my dad was standing over my shoulder giving me executive courage.

With my business experience and Dr. Dasi’s clinical expertise, it did not take long to realize what a great team we would be. We formed DASI Simulations in December 2019. Then, COVID-19 hit, and the world around us stopped. We, however, did not stop. We worked continuously night and day by Zoom making something very special out of an idea and fortunate circumstances. It was by pure serendipity that I met Dr. Lakshmi Dasi and I will be forever grateful.

0{{current_slide_index}} 0{{total_slide_count}} COMPANY FORMATION & PLATFORM DEVELOPMENT 2020 DASI Simulations was founded in Dublin, Ohio, with a mission to improve structural heart outcomes through 3D AI-driven patient-specific modeling. The team began developing a proprietary cardiac simulation platform for TAVR and complex valve planning, built on a device-agnostic approach to support multiple valve technologies and personalized treatment decisions. 2025 2021 0{{current_slide_index}} 0{{total_slide_count}} COMPANY FORMATION & PLATFORM DEVELOPMENT 2021 DASI initiated early clinical collaborations with premier academic medical centers and structural heart teams, supporting initial real-world TAVR cases—particularly in complex anatomies. These efforts demonstrated the feasibility of simulation-driven valve sizing and positioning to enhance procedural planning. 2020 2022 0{{current_slide_index}} 0{{total_slide_count}} Reimbursement & Regulatory Milestone 2022 DASI achieved major regulatory and reimbursement milestones, securing FDA 510(k) clearance for its patient-specific cardiac simulation technology and for DASI Dimensions, its image-based automated measurement solution. The company also obtained CMS reimbursement approval for pre-procedural cardiac simulation services, enabling scalable clinical adoption through established payment pathways. 2021 2024 0{{current_slide_index}} 0{{total_slide_count}} Clinical Expansion 2024 DASI expanded adoption across leading U.S. structural heart programs while increasing its presence at major cardiology conferences. Live pre-case planning demonstrations further showcased how simulation-driven insights enhance procedural confidence and decision-making. 2022 2025 0{{current_slide_index}} 0{{total_slide_count}} Partnerships & Thought Leadership 2025 DASI partnered with leading academic and health system institutions, including Cleveland Clinic, while maintaining a device-agnostic approach in collaboration with industry stakeholders such as Medtronic. Rapid commercialization followed, resulting in nearly sixty commercial agreements to date. 2024 2020
