The TAVI procedure doesn't always follow the plan. So why should the plan stay the same? We spend hours planning a TAVI procedure. Valve sizing, coronary risk, deployment depth, working angles, and predicted expansion. But things change inside the cath lab. The valve may land deeper than intended. There may be some tilt, incomplete frame expansion, or residual PVL. These changes can affect coronary risk, valve hemodynamics, and future treatment options. What if the plan could evolve as the procedure unfolds? That's why we built TAVIAssist, an AI-powered, voice-controlled assistant integrated with QuanTAVI. Just ask: 🎙️ "Scroll from the STJ to the annulus." The CT moves through the aortic root. 🎙️ "Where's the biggest calcium?" It identifies the location and takes you there. 🎙️ "How do I remove the parallax?" It provides the C-arm angles from the double S-curve. 🎙️ "If I deploy a 23 at 4 mm, what's my VTC?" It calculates the coronary distances for that scenario. 🎙️ "Show me the expansion." It reconstructs the deployed valve frame in 3D from two fluoroscopic views. No keyboard. No mouse. Just talk to your plan. This isn't about replacing the operator's judgment. It's about connecting pre-procedural planning with what actually happens during the intervention. The TAVI plan should not stop at the cath lab door. It should evolve inside the cath lab. QuanTAVI by Sphygma. Built by operators, for operators. Watch TAVIAssist in action below. Research use only.

Most TAVI plans are still made by someone other than the operator who implants the valve. We're building QuanTAVI at Sphygma to change that: CT-based planning for aortic valve procedures, designed by the cardiologists and surgeons who run these cases. From the CT to the cath lab: → Automatic aortic root measurements, each one reviewable on the images → Every valve compared side by side, with the reasons behind each size → Instant simulation of the deployed valve: coronary obstruction, root rupture and conduction risk, before the lab → Physics-based (FEA) prediction of how the frame will expand → Lifetime planning: choose today's valve so the next TAVR stays possible → TAVIAssist on the table: working views, valve overlay on fluoro, and the plan by voice → Expansion review after deployment: the frame traced on fluoro and rebuilt in 3D TAVR, SAVR and valve-in-valve on one platform.
