TAVR has come a long way—from a high-risk bailout procedure to a precision-driven, patient-specific therapy.
In this MurmurMD case discussion, Dr. Matt Summers (Sentara Heart Valve Center) joins Dr. Aiden Raney to explore how new data, AI modeling, and simulation tools like DASI are transforming how interventionalists choose between self-expanding and balloon-expandable valves. A real look into contemporary approaches to valve therapy decisions.
Key insights covered:
The evolution from procedural survival to lifetime valve strategy
How hemodynamics and durability data are reshaping valve selection
Using predictive modeling (DASI) to prevent annular rupture and coronary occlusion
Real-world lessons from redo TAVR and valve-in-valve procedures
Why commissural alignment and cusp overlap have changed the game
What next-generation AI tools mean for precision TAVR planning
How large-volume centers are integrating data, imaging, and simulation into every case
This conversation bridges clinical intuition with digital precision, offering a glimpse into how the next era of TAVR will be designed—patient by patient, model by model.
