Dr. Craig Smith - What Are the Risks of Aortic Valve Replacement Surgery?

Read Transcript

For the risks of Aortic Valve Replacement surgery, done conventionally with open heart surgery include all the risks of open heart surgery, things like bleeding, like stroke, like transfusion, things of that sort. Some of those risks cross over with transcatheter valve replacement, TAVIs, some don't.

Atrial fibrillation bleeding tend to be more concentrated in the surgical population, but perhaps of less consequence than things like stroke. In the comparison of transcatheter procedures to conventional surgery, stroke has been one of the big issues because in the most recent comparison of this, comparing surgery to the transcatheter approach, stroke still remained about twice as possible as likely in the transcatheter group as in conventional surgery.

Not talking about big numbers, it was about 4% versus about 2%, but still, just enough to give pause on that particular risk. Transcatheter approach also has a little greater vascular risk of complications to the blood stream and the great blood vessels because it's put into the very large device. Now that would change as the device gets smaller which it will, which it did.
