Talk:Artificial heart valve

message: From the article:
"The most used heart valves in the US and EU are those utilizing tissue leaflets. Mechanical valves are more commonly used in Asia and Latin America.
Are you sure about this?  I've heard the exact opposite, that in the US, mechanical valves are most common in US, while porcine valves are used mainly elsewhere.--198.37.18.118 07:38, 20 March 2006 (UTC)

message: This entire section refers to a syndrome generally not recognized in Western/eastern medicine, and perhaps promoted by it's namesake only. It should be removed unless credible references (yes in English) can be sourced. EtherDoc (talk) 05:06, 20 February 2012 (UTC)
thread_title: Psychotherapy section

message: The article seems a little heavy on mechanical and a little light on tissue, especially when considering actual usage ratios and trends.
The article also needs to go into detail on:
-percutaneous technologies
-homografts
Any takers?
Also, the section on Caged-Ball Heart Valves is completely at odds with the page wiki/March_1960 - compare March 10th with this page.  — Preceding unsigned comment added by 2A00:23C8:3B02:4E01:4570:5708:2921:5CA2 (talk) 16:11, 30 August 2023 (UTC)

message: I have had someone from a company who makes these say there is Tungsten in them, not Titanium.  This is because Tungsten is easier to see via x-rays and it is not toxic.
A variety of materials are used in heart valves.  Radio-opacity is achieved by use of addition of elements with a high atomic number.  While tungsten may be used in some heart valves, it is not ubiquitous.  Various grades of stainless steel, cobalt-chromium and molybdenum alloys, and titanium are also used.  Barium sulfate is added to siloxanes (commonly, but incorrectly, referred to as silicones) and other polymers to provide radio-opacity.  —Preceding unsigned comment added by 66.155.145.12 (talk) 16:52, 28 July 2008 (UTC)

message: An editor has been adding content specific to a brand of bileaflet valve, On-X®, to the section on bileaflet valves. I have removed this content for the following reasons:
This article is an overview of the topic and does not, at present, address the differences between, and putative merits of, designs and models within the categories "caged-ball", "tilting disc" and "bileaflet". The bileaflet section contains nothing on other manufacturers' models - and I'm not sure that it should, unless an independent review of the differences and merits of the various models can be cited. The little I know about medical devices tells me that the whole field lacks rigorous independent analysis of safety and efficacy, but perhaps I'm mistaken there, or perhaps this is an exceptional case and there is a recent scholarly review of the products in use in this category that we can rely on.
If that is the case, a concise overview of the different bileaflet designs may be warranted. 
Writing for Wikipedia medical articles is governed by policies and guidelines. Here I have in mind (a) Wikipedia:Neutral point of view - in particular, this section: WP:DUE, where it says "An article should not give undue weight to any aspects of the subject but should strive to treat each aspect with a weight appropriate to its significance to the subject" (presently, the data on On-X® gives undue weight to one model) and (b) Wikipedia:Identifying reliable sources (medicine), which recommends medical content be supported by independent scholarly reviews, graduate-level textbooks, professional or government practice guidelines, etc. (presently, the data on On-X® is supported by two primary sources - trial reports). --Anthonyhcole (talk) 07:24, 7 July 2012 (UTC)

message: Acute thrombosis of a mechanical valve is a potentially life-threatening scenario. doi:10.1111/jth.12577 compares two management strategies (open surgery or thrombolysis) and concludes that while thrombolysis may lead to better outcomes, they could not exclude that it was offered to those who were relatively well, thereby biasing the results.
