I can't help it. Since you've been referencing mechanical valves as carbon valves, I had to get a picture of it. Now I don't know about you, but I think mechanical is cleaner.

I've actually felt that calling them mechanical valves makes them seem like clumsy, complex, old-fashioned, clanking metal things, with plungers and push rods and lots of moving parts that could break. Similar to the crud-covered, misfiring cast iron engine that the dainty part in your photo must have come from.
In fact, they're incredibly smooth, fourth-generation carbon, with sleek, unbroken lines, deceptively simple in operation, and are one of the most choice examples of successful, ultrafine tolerance manufacturing available today.
Much like comparing an old, finger-dial, black bakelite desk phone with a RAZR.
However, if it offendeth thee, I might accept the results of a poll for:
_ Mechanical, _ Carbon, or _ Call It Anything, But Don't Call Me Late For Dinner,
if it's decisive or I see any real heat in the comments.

So how would we divide valves most accurately?
Tissue and Mechanical?
"Tissue" valves work exactly the same way as "mechanical" valves. Both are completely mechanical in operation, and function passively, opening and closing from pressure on one side of the leaflets or the other. So mechanical applies to both...
"Tissue" is not a method of functioning and "mechanical" is not a substance from which valves are made. As comparatives, the terms "tissue" and "mechanical" aren't even apples and oranges. They're apples and pinecones...
Manufactured amd nonmanufactured valves?
Well, pyrolytic carbon valves are manufactured valves. But so are the Edwards bovine valves, which are manufactured from bovine pericardium, and the St. Jude mixed grille valve that is both porcine valve pieces and bovine pericardium. Even the nearly-natural Mosaic has a demistent added, which would technically be manufacturing. Too confusing...
ACT-required and Non-ACT-required?
Oohh...too clumsy and awkward. And what if the On-X winds up as an aspirin-only crossover? Semi-ACT-required? Same with using Warfarin or aspirin in place of ACT. No, too ugly...
Homografts, Xenografts and Carbonografts?
This would do, but we'd always be explaining them...
Tissue and Carbon?
Works for me. If we get something from a new material, such as Elasteon, we just add it (probably as the "polyurethane" group). Direct. Comparative. Simple. Descriptive...
...and when the box was opened, all manner of things came forth from it, both wonderful and vile, all helter-skelter and entirely irretrievable...
Best wishes,

Good Explanation Bob,
BUT, the Medical Profession and most Medical Literature classifies valves as Tissue or Mechanical despite the fact taht one is a material and the other is an operational mode.
I suggest that combining Carbon and Mechanical might be less confusing, especially to newcomers who likely will NOT make the connection without 'guidance'.
Mechanical (with Carbon leaflets)

I know that this site has always designated valves as "tissue" or "mechanical". I would find it difficult that those two classifications might confuse people as the doctors seem to use the same descriptions. I would think "carbon" might cause more confusion and lead people to believe there is a third choice. Just MHO.
I agree with Gina. The KISS principle should apply.

Tobagotwo - thanks for your attempt at making the mechanical valve sound classy . I do understand your point. But I agree with Gina, "mechanical" is the term used by doctors when they refer to that type.
And according to RCB - I have 4 carbon valves! Does this make me a diamond in the rough???

Hardly- it makes you a multifaceted rare gem!

Well, scholarships sure come in handy when attempting to pay for a college education.
Or, wait, is that a colledge edumacation?

Clarifying definitions so as not to confuse new members and others coming here for information is not anal retentive, it's the responsible thing to do. It may be a case of semantics, but if we can eliminate confusion, we should do so. It's like someone not knowing that a homograph and a cadaver valve are the same thing.

Hey, I was just reading some of his articles and the word "Carbon Valve" looked at me and said, Thou shall google thy image, so that is what I did and this is what I came up with.rckrzy1 said:

!One thing has been really bugging me though and that is, "Where is that quote from, 'and when the box was opened...'?"

Last night a valve of the fuel pump in my car failed And I "failed" in the eyes of the beautiful girl next to me
Am I vowed to have defective valves everywhere in my life!
For luck, the fuel pump's valve costs something like 10$ And it's not a carbon...

You do seem to have valve problems in general.
So the girl didn't look on a failed fuel pump as a nice opportunity?
