RAGING HYPOTHETICAL:

–Next time you won’t need to – because you read this post.

WHAT’S A TAVI?

Transcatheter Aortic-Valve Implantation (TAVI) for patients with severe aortic stenosis who are not candidates for surgery.

What it looks like:

How it is placed: (so cool and worth watching)
The implantation procedure involves accessing a femoral artery, performing balloon valvuloplasty, then advancing the device across the native valve. During rapid right ventricular pacing, a balloon is inflated to deploy the valve and the frame.

Evidence it works:

At one year, the rate of death from any cause was 30% with TAVI vs. 50.7% with standard treatment (balloon aortic valvuloplasty and or medical therapy)

Not so good: TAVI had a higher incidence of strokes and major vascular complications compared to standard treatment, however this was included in rate of death.

Now you know πŸ™‚
