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.

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. Built by operators, for operators.

if you want i can give you link to my (underdevlop) app for better Visual understanding of 3d wiring

but this is after TDAR picture, this wire seems in Dx? not LAD.
Thats true for Medtronic valve where more radial force is needed. In my opinion this one doesn't require much oversizing. Here is one reference
We implanted @MDT_StructHeart Evolut R valve during a live case at the TWAL Structural Heart Summit. Our procedure was guided by double and triple S-Curve techniques for precise depth and parallax removal. We utilized our in-house-built prototype software, TAVIAssist. @TAVRBot

Seems like a bubble as it extravasated. But you know the case better.

Excellent skills. Here is demonstration of my app NAVIWire to make 3D wiring easy for beginners.
Exciting news! We successfully performed doppio-BASILICA ✂️ on a surgical valve with radiolucent posts using our very own prototype software, BASILICA-Assist 👨💻. This innovative software allowed us to simulate the current orientation of the valve in real-time. #CardioTwitter
Alhamdulillah got first prize in 51st Cardiocon for my innovation on CTO PCI software application on 3D wiring. #PCS #Cardiocon #MedTwitter #CardioTwitter

Elderly male, inferior wall MI, primary PCI, did provisional but lost OM. Could not rewire the OM despite many wires . No sidehole catheter available.
78m DVCAD, CTO RCA & LAD, surg declined, operator said tried to 'drill' gaia 2nd got stuck. Pulled back without MC. Wire broke. 3cm radiopaque spring and ~10cm core inside LAD & LMS. Ref to surgery who declined and sent to us. What to do? @NosairMohamed @OsquiGuzman @turilrh
