The app helps clinicians accurately size bicuspid valves for TAVR procedures. Simply input CT scan parameters to receive personalized valve size, inflation volume, and alternative size recommendations. It also evaluates valve fit on important anatomical paramaters like LVOT and annulus, allowing real-time adjustments for precise outcomes. Ideal for optimizing procedural planning and enhancing clinical decision-making.
