CHD

I've been recently trying to work on the a group of CHD related articles, including expansion of TGA to include l-TGA (the portion already posted was what I had written before I realized that there was another variation) I have been very close to posting it for a while and have been waiting for a naming dispute to be worked out for another related article. It would be great to have someone collaborate on this article with me...if you are interested, please let me know on my talk page. I look forward to hearing from you. bcatt 01:32, July 21, 2005 (UTC)

Hi Bcatt

I'm also interested in the various CHD articles.

Regarding the TGA/TGV dispute, I think it is a no-contest in favor of TGV.

Ask 100 people what is TGV and 99 will draw you a sleek locomotive.

Which other CHD articles are you working on?

Hi again, I've contributed to different extents on the following heart-related articles: the Transposition articles, right and left atrium, Prostaglandin, heart chamber, cyanotic heart defect, cardio, cardiac catheterization, and blood vessel. I've got a very large transposition edit in the works, which is my primary focus at the moment...everything else I am doing is mainly small details that I notice when reading the pages I'll be linking to.

Please do read my arguments for disambiguation on the TGV talk page...Wikipedias naming guidelines are quite clear that this page should be a disambiguation, with each of the articles being placed on pages under their respective extended names. The information provided by Wikipedia about naming are quite clear that it is not about "what most people would think of" but of "what is most encyclopedic"...anyway, those arguments are all there on the talk page, I encourage you to take a look at them.

What are your areas of interest in regard to CHD's? bcatt 12:01, 16 November 2005 (UTC)

Capitalization of article names

Hi Bcatt. You've made several great contributions to articles about congenital heart defects. Keep up the good work! Just one minor thing: only proper names should be capitalized in article names. Dextro-Transposition of the Great Arteries is incorrect. It should be dextro-transposition of the great arteries. However, Tetralogy of Fallot is correctly capitalized since Fallot is a proper name. See Wikipedia:Naming conventions (capitalization) if you have any questions. Thanks! —Brim 16:24, 18 November 2005 (UTC)

Since these articles are the names of medicale conditions, wouldn't they be capitalized? I was under the impression that these are proper names...thanks for the help bcatt 19:30, 18 November 2005 (UTC)

No, medical conditions aren't proper nouns. The only time that they should be capitalized is when they contain the name of a person. It might be a bit confusing since on Wikipedia the first letter of every page is capitalized, which may have mislead you into thinking these terms were meant to be capitalized.

Here are some examples of proper usage to help you get the hang of it:

• correct:heart, incorrect:Heart - not capitalized since it's just a word
• correct:myocardial infarction, incorrect:Myocardial Infarction - two words, but not capitalized since none of these are proper nouns
• correct:Down syndrome, incorrect:Down Syndrome - first word capitalized since it's named after a person
• correct:metabolic syndrome, incorrect:Metabolic Syndrome - not capitalized
• correct:Thrombotic thrombocytopenic purpura, incorrect:Thrombotic Thrombocytopenic Purpura - not capitalized

Hope this helps! —Brim 21:21, 18 November 2005 (UTC)

Talk:Dextro-Transposition of the great arteries#Comments

Hi, wondering if you accidentally left off the end of your sentence in your comment on the d-TGA talk page...it seems to have been prematurely terminated...when it is an what? Thanks bcatt 19:37, 18 November 2005 (UTC)

Oh yeah, I was also wondering about the infobox...what is the ICD-9 for d-TGA? Same as l-TGA? bcatt 19:38, 18 November 2005 (UTC)

Per your two questions -- I found the ICD9 for dTGA (745.10) at [1]. And you're right -- my comment did cut off in midsentence. I made the mistake of linking to a category, so the category appeared at the bottom instead of in the paragraph. Sorry for any confusion. And thanks again for all the great content you wrote. --Arcadian 21:19, 18 November 2005 (UTC)

d-TGA

Hi. I was wondering what the other arrangements of the arteries in d-TGA are, as I would like to be able to describe them in the article, rather than highlighting one and mentioning the others in passing. I have taken this out for now, as I cannot verify it. (originally unsigned) bcatt 13:17, 19 January 2006 (UTC)

I will look up the percentages of other relative positions of the great arteries at work tomorrow. However; I think there's a limit to detail in this (and other) cases. Remember, anything is possible in congenital heart defects (almost). There are variants that are reported in one or two cases world wide. But I will look it up. --Ekko 16:47, 19 January 2006 (UTC)

Hi, I hazard the guess that it was you making the comments about spatial orientation of the arteries. Go take a look, sufficient information or too much/little? --Ekko 07:42, 20 January 2006 (UTC)

I'm thinking that this is describing a general category of heart defects, rather than specifically d-TGA...I don't have that particular reference, but from the ones I do have, it sounds like "anterior and to the right" is d-TGA, "directly anterior" is probably overriding aorta, and "anterior and to the left" is l-TGA, "side by side" and "right and posterior" yet other variations of Transposition of the great arteries with other names. The coronary artery patterns do need to be mentioned though, hopefully in more detail - but under the "variations and similar defects" is where I think it fits best. The article does already mention coronary artery patterns, but not until quite late in the article, under "surgery"->"minor"...so it does need a mention as to the fact that there are variations...particularly in regard to whether coronary artery variations can happen alone, or whether they are directly connected to birth defects generally or certain ones in particular. Any statistical info (eg: X% of d-TGA cases have this coronary artery pattern.) should go under the statistics heading at the bottom; but, and I realize I'm probably repeating myself :P, the coronary artery patterns do need a descriptive mention under "variations". Thanks bcatt 00:18, 22 January 2006 (UTC)

For a select few of us this is exiting stuff! The point that you forget is that in all the scenarios i mentioned the ventriculo-arterial connection is strictly right ventricle-aorta and left ventricle-pulmonary artery. From this one can deduct that the outflow tracts of the ventricles have to be more or less spiralled around each other to accommodate different spatial relations between the arteries (or rather the valves of the arteries) with the arteries still being parallell.

An overriding aorta is not a diagnosis by itself, but is a part of other complex heart defects, like tetralogy of Fallot (where the is no transposition of the arteries) or double outlet right ventricle (where a transposition of the arteries is part of the picture). The mistake of thinking "backwards", to surmise that a certain arrangement of the arteries tell anything about the arrangement of the ventricles and/or the connection between ventricles and arteries is a common one. Makes for difficult diagnostics!

I think this is an excample of the strenght of sequential segmental analysis of the heart: step by step go through the heart, only describe what I see, make no asumptions and "quasi-genial lightning diagnosises", desribing the heart as "which rooms are connected by which doors".--Ekko 08:20, 22 January 2006 (UTC)
