Dr. Dasi’s research is focused on heart valve pre-surgical planning using artificial intelligence (AI) software that predicts the heart’s physical interaction with implanted devices and its implications on complications, outcomes, and lifetime management.
Although heart disease is a global health issue, current heart surgery planning suffers from outdated tools and techniques that lack accuracy and efficiency. To address this issue, Dr. Dasi has developed Precision TAVI (Transcatheter Aortic Valve Implantation), a predictive modeling software that creates a “digital twin” of the patient’s heart and provides physicians with a personalized treatment plan to reduce the risk of common post-surgical complications. Importantly, patients who were once considered inoperable due to their complex disease state are now candidates for trans-aortic valve replacement.
Precision TAVI received full U.S. Food and Drug (FDA) approval as the world’s first predictive modeling software for valve replacement, marking an important step in commercializing the technology and establishing it as the new standard of care. The life-saving software is currently in use in dozens of hospitals nationwide and holds the promise of fewer medical interventions, significant healthcare cost savings, and better quality of life for patients.
In the future, Dr. Dasi hopes to expand the use of this technology to applications in pediatrics, neurovascular and endovascular surgery, and all cardiac structures (e.g., mitral and tricuspid). The goal is to fully integrate the modeling software with AI robotic surgery.
“One surgery at a time, our technology helps avoid complications, enables lifelong planning for optimal structural heart care, and has the potential to save billions in unnecessary costs,” said Dr. Dasi.
