Talk:Transcatheter aortic valve replacement

Transcatheter Aortic Valve Implantation

In europe/UK they have used Transcatheter Aortic Valve Implantation (TAVI) since about 2007. 7,000 such procedures are expected to be performed in Germany in 2010. Approx 1000 have been done in UK and NICE have approved it for patients not suitable for open heart surgery.

It sounds like the same/similar procedure but US trial implanted cow heart valves so maybe it counts as a different procedure and justifies a separate article. Rod57 (talk) 00:11, 8 December 2010 (UTC)

How is the existing valve removed?

Having trouble figuring out how the existing, original valve is removed. Can someone add detail on this? CrocodilesAreForWimps (talk) 05:07, 9 November 2013 (UTC)

I have corrected misleading information since the native valve is not "removed". Artificial valve is "implanted" over the native valve; therefore the correct term is Transcatheter Aortic Valve Implantation and not "replacement". Replacement of the native valve is possible only surgically during open-heart surgery with direct removal of the native valve. 31.51.253.134 (talk) 19:05, 10 March 2024 (UTC)

The original valve is not removed. Instead a replacement valve is positioned inside the original degenerated valve and implanted inside. The replacement valve is suspended in place in part by the original valve. This is in contrast to surgical aortic valve replacement, where the original valve is usually cut out. Surprisingly, the resulting orifice area of the replacement valve after surgical aortic valve replacement is still smaller than the the orifice area of the replacement valve after transcatheter aortic valve replacement.

How is this procedure done, in words of one syllable?

How is the transcatheter valve actually inserted, in layman's terms? This is what I had hoped to learn, but did not find. The term 'method of entry' is not sufficiently clear to a non-doctor. Is it an injection, for instance? Ginestre (talk) 16:50, 21 January 2015 (UTC)

The doctor enters the artery using a needle, then makes the hole in the artery bigger so that tubes can be inserted. Then a tube containing the new valve is passed into the artery and all the way back to the heart. The hole is closed at the end. I hope that is simple enough terminology. — Preceding unsigned comment added by 2A02:C7D:2BBD:8900:48F0:6F83:EED3:2EA (talk) 20:19, 16 July 2018 (UTC)

Move

Move of this article requires discussion. Thus moved back. Regardless of where it is moved to the term should not be all caps. Prior / current term used here [1] Doc James (talk · contribs · email) 12:32, 11 October 2015 (UTC)

This procedure is no longer referred to as PAVR. It is now solely referred in medical literature as transcatheter aortic valve implantation or replacement. I believe this is up for discussion however a quick PubMed search will confirm my point. Captain108 (talk) 20:43, 5 November 2015 (UTC)

Which ref are you looking at? These people use PAVR [2] and this 2014 review [3] Doc James (talk · contribs · email) 00:07, 6 November 2015 (UTC)

The PARTNER trial, one of the most definitive trials for this procedure refers to the procedure as TAVI. [4] Same with the Ottawa Heart Institute [5] and the American Heart Association calls it TAVR [6].

I did my bachelor's dissertation on TAVI and I saw it almost entirely referred to as TAVI in all the papers I read. Only the earliest papers circa 2002-2004 when the procedure was newly developed did I see it referred to as PAVR. This article discusses the debate between TAVI and TAVR, but nowhere did it mention PAVR. [7] Captain108 (talk) 00:18, 6 November 2015 (UTC)

Maybe try a WP:RM for further input. Mass Gen uses PAVR [8] as does the this review [9] ICD also uses the term [10] Doc James (talk · contribs · email) 06:07, 2 December 2015 (UTC)

please advise on Huber link to device paragraph

Jytdog You removed C Huber's text to his page, although the innovation is very related. Would you suggest I expand a bit on the text? The references to the innovations are already on Huber's page...please advise. Thanks!KHBibby (talk) 03:39, 22 January 2016 (UTC)

No, the content is way too promotional. This is against Wikipedia's policies. See WP:PROMO. Jytdog (talk) 04:22, 22 January 2016 (UTC)

Edwards TAVI valve?

I would remove Edwards valve since I discovered it is no more available on the market; instead, I would insert the Jenavalve TAVI. — Preceding unsigned comment added by Fredthewise (talk • contribs) 20:45, 26 April 2016 (UTC)

Edwards valves are very much on the market. I'm not sure where you "discovered" this false information. Edwards makes the Sapien 3 valve. — Preceding unsigned comment added by 2A02:C7D:2BBD:8900:48F0:6F83:EED3:2EA (talk) 20:15, 16 July 2018 (UTC)

Percutaneous aortic valve replacement, why this title?

Why not just call it transcatheter aortic valve replacement? Percutaneous is not a wider term.

A lot of the procedures are not percutaneous (i.e. having the catheter put in by poking a hole in the skin). Many procedures require surgical techniques for access, e.g. transapical, transaortic and cutdown in transfemoral. — Preceding unsigned comment added by Thefatmonkey (talk • contribs) 14:02, 18 March 2017 (UTC)

+1 for the change in title EncycloABC (talk) 14:26, 28 May 2019 (UTC)

This should be requested on WP:RM. I agree in principle. JFW | T@lk 22:14, 28 May 2019 (UTC)
