Laza’s AI Heart Model Marks FIH Use in Ultrasound-Guided Cardiac Procedures 

September 3, 2025—Laza Medical, Inc., which is developing artificial intelligence (AI)–powered robotic ultrasound image guidance technology, announced the successful completion of its first software-only human cases at Oregon Health Sciences University Hospital in Portland, Oregon.

According to Laza Medical, a privately held portfolio company of Shifamed, LLC, this milestone marks the first time Laza’s real-time, AI-based heart model has been evaluated alongside real clinical procedures. The software operated concurrently during live cases to enable retrospective analysis and performance assessment, reported the press release.

Laza stated that its software constructs a patient-specific, three-dimensional (3D) heart model in real time using ultrasound data alone. Validating this guidance software is a key step toward first-in-human testing of Laza’s complete intelligent robotic imaging system, noted the company.

Scott Chadderdon, MD, and Firas Zahr, MD, commented on these developments in the company’s press release. Dr. Chadderdon is Head of Cardiac Imaging and Dr. Zahr is Head of Interventional Cardiology at Oregon Health Sciences University Hospital.

“As a cardiac imager, it’s exciting to see this kind of innovation entering clinical evaluation,” stated Dr. Chadderdon. “There is a significant need for solutions that can help make high-quality imaging guidance widely accessible for structural heart procedures.”

Dr. Zahr added, “Having a live, echo-derived 3D model would give me consistent anatomical and spatial context throughout the case. This study is an important first step in assessing this capability. Once this has been validated, layering in robotic control could unlock a whole new level of efficiency and autonomy.”
