Heart Surgeon Takes Notes from da Vinci 191

Posted by ScuttleMonkey from the next-we'll-be-using-mayan-farming-techniques dept.
vivekg writes "Leonardo da Vinci probably never thought he had the proverbial Holy Grail to a revolution in heart surgery. Almost 500 years after da Vinci's death, intricate diagrams of the human heart made by him have inspired a British surgeon to pioneer a new way to repair damaged hearts."

    Old science is not necessarily bad science. In fact, the hallmark of good science is how well is holds up over time and continued testing. Granted, Leonardo de Vinci was not "practicing" modern science. Rather, he was using the oldest form of science which is observational science. However, this approach is still valid and tends to be the most robust type of science which, like Leonardo discovered can also lead to the most controversial reactions from people who have investments in the current understanding of certain topics........... *cough* *cough*, like evolution.

      On the "evolution" (technically modern evolutionary synthesis) comment,

      At least 90% of laymen have no concept of what the theory says or predicts, nor how it is tested. The way the theory gets presented in high schools across the country is absolutly unacceptable. Such a muddle, confused, and illogical presentaion of science directly leads to such pseudoscience as intelligent design. Experience has forced me to agree with von Mises, public schools should be banned from teaching science because they incapable of presenting it correctly and will only cause confusion.

            I'm glad to hear it! Please let me know when I can opt not to have my tax money go toward the war in Iraq.

            What's that you say? I can't opt out of the payment because I can't opt out of the benefits? How is that different from universal education? Or is there a way to opt out of a strong economy and an educated workforce that I'm unaware of?

            Shine on you crazy diamond!

          • The public schools should focus on providing a basic education for those who have no other option. That is: reading, writting, and arithmetic should be the initial focus.

            You're on the right track, but I think you're not going far enough. If it was up to me, I'd institute mandatory flogging for everyone going to school. That way, the only people (or kids) being educated would be the ones that really wanted to, and this system would produce only first-rate geniuses!

        • Personally I believe that the problem is the increasing centralization of control over the schools. This includes all Federal interference and all state interference.

          Schools should be funded locally, and have local control. Unfortunately, the various levels of government have stolen the sources which were traditionally used to fund schools, so local funding is a problem which needs solution. This doesn't make it any less necessary. If the local students are to be taught lies, it should be because the local citizens have decided that that's what they want their children taught. (They will suffer the appropriate consequences...but their folly should not be forced on everyone else.)

          This has been my position for over 2 decades, and everything I've seen during that period of time has only reinforced the opinion. Only at the college or university level should the state (e.g., Idaho or Pennsylvannia) have any involvement. The states should run the colleges, because specialized education needs to draw from too large an area of population for local funding to be reasonable. They should be tuition free, but have appropriately difficult admissions requirements, and may limit the number of open spots for admission. (The state can decide how many English majors it needs to educate, and how many BioChemists, and fund that many classes of the appropriate type.)

          At all levels, private schools should continue to be an option.

          Some will argue that this will unfairly penalize the children of poor cities. In my experience in those cities the federal government alone extracts more funds nominally for education than are expended on schooling by all levels of government combined. This may not be true everywhere, but it's certainly largely true. Also, the most important parts of schooling don't require much in the way of funding, though they do require the cooperation of the parents. Thus if the parents will not cooperate with the local school, the school should have the right to refuse to allow the student to attend lessons. Disruptive students are not something that should be tolerated...but when schools are used in the way in which they are currently, that's what you get.

          That said, not all students are academically inclined. There needs to be a flexible "tracking" system, which allows those mechanically inclined to develop their skills as well as a track which allows the academic students to develop THEIR skills. I envision one hour per day during elementary school (after third grade) where students experience are instructed in "enrichment specialties", which should include things like band, set theory (arithmetic should be mainstream...by rote, and sorry), wood/metal/plastic shop, etc.

          OTOH, this requires a fairly large elementary school. Other benefits would accrue if elementary schools were local enough that all students could walk to them. That way the neighborhood kids would study together. This would probably mean that, e.g., grades K-3 would all be taught in the same room by the same teacher. (If you have enough students to split this in two, perhaps you could split them by distance rather than by age.) This WOULD be an acknowledged combination school and babysitting service, and play areas would be an important part of the situation. Teachers in this class would be expected to LIVE in the school, and keep it open. Provisions for substitutes would be necessary. Etc. Class sizes would be small, but the salaries would be enough to live on given the free rent. (I envision that most of these teachers would start out as mothers raising their kids. So room would need to be sufficient to handle not only the teacher, but also a husband or other partner and their children. With a safe fenced area around it which is the school yard.)

          N.B.: A lot of what I'm proposing is just my idea spinning of how it might ideally work out. The important parts are:
          1) No central control.
          2) Local choice on funding & curricula & environment.

      Could it be your own inflated value of classical music that's out of wack? Britney Spears sucks in more ways than I can count, but I see no intrinsic value in classical music over any other form of music. You really want to know why Britney Spears outsells music that doesn't suck? It's because the music industry thinks its only consumer is the 13-22 crowd. Britney Spears captures probbably half of that age range, so she sells a lot.

      I don't even know where to start with this statement. My guess is a lot of research isn't driven by pursuit of money. Just look at the research done at major universities and you'll find most of it isn't profit driven. Research that isn't profit driven is important because companies don't like funding things whose value isn't immediately apparent. When you take on that attitude you get a bit of tunnel vision. There's obviously a lot of research that is profit driven. What's wrong with that? Without it you'd just have less research going on, not more. Unless the profit driven research is somehow threatening the non-profit driven research I fail to see any problem with profit driven research.

    Mitral valve prolapse [nih.gov], fortunately, is not deadly. But the usual treatment always has the potential danger of valve infection. I hope the new technique will help prevent that problem.

    You have got to be kidding me! This passes for news? Some doctor says 'whoaaaa mannnn, Da Vinci made some nice drawings' and then invents a new way to repair the heart, and the media links the two together. There is NO mention of what the new procedure consists of or why Da Vinci's drawings helped him invent it. I find it very hard to believe the Da Vinci really had some understanding of heart physiology that we don't and when the article makes no effort to convince me otherwise...well, color me skeptical.

    Go read http://www.guardian.co.uk/life/badscience/ [guardian.co.uk] backstories and learn why you should never listen to the mass media when it comes to scientific discoveries. I'm really surprised this got posted to /.

      Maybe this article Da Vinci decodes heart valve surgery explains it better [news.com.au]
      rancis Wells, a consultant cardiac surgeon at Papworth Hospital in Cambridge, England, said he had a "eureka moment" as he pored over drawings and notes by the artist in the royal collection at Windsor Castle.
      With Da Vinci's understanding of the importance of the opening and closing phases of the valve, Mr Wells has worked out how to restore the valve's normal and full variability in opening and closing properly.

      "That has been a big step forward," he said yesterday.

      So, yes the work of Da Vinci 1500, did lead to some modern improvments in medicine today!

        I think this is the better part of the article. This quote actually explains what the new technique is.

        Until now, surgeons have narrowed the diameter of the valve by removing a square portion of one of the flaps. Now, by closing the gaps on each side of the prolapsing flap and cutting out the excess tissue in a V-shape, the surgeon can make the valve work properly again.
        • Sure, there's one sentence that alludes to the new technique, but why was this not an option before? What was preventing people from simply fixing the valve? This seems like the natural solution to me - it seems obvious that narrowing the valve is an inferior solution to simply fixing it. There's no meat to the article.

      1. Read article.
      2. Don't get answers to questions.

    When Leonardo was alive, 500 years ago,there was no monopoly; barbers and other people with dubious trainng were involved in medicine.

    Before Leonardo, in the early Middle Ages, say, when the Decameron was written (13++) physicians were not called "Doctors" because they did not have doctoral degrees. Only Theologians and Lawyers were Doctors. The best eaxample is Toma De Aquino, "Doctor Universalis" who had all the doctorates of the time, but was no physician.

      "there was no monopoly; barbers and other people ..." Yeah and numerous people were killed in their dubious attempts at medicine. BTW medicine is not a monopoly ... anybody can join if you (i) finish medschool (ii) pass an exam. If you are not smart enough to do these ... there is no need to involve antitrust law in this.
      • Each state in the United States has a medical board that requires licensing to practice medicine in that state, and they are all members of the federation of state medical boards, right? While this sounds like a monopoly to me, it's a licensure monopoly by the state, which is a constitutionally defined government power. States have power to license professions that effect the public interest. You can't bring racketeering charges against the state even if you wanted to, the state is by definition a monopoly

    A mechanic was removing a cylinder head from the motor of a Harley, when he spotted a world-famous heart surgeon in his shop. The heart surgeon was waiting for the service manager to come take a look at his bike. The mechanic shouted across the garage, "Hey Doc can I ask you a question?"

    The famous surgeon, a bit surprised, walked over to the mechanic working on the motorcycle.

    The mechanic straightened up, wiped his hands on a rag and asked, "So Doc, look at this engine. I also can open hearts, take valves out, fix'em, put in new parts and when I finish this will work just like a new one. So how come I get a pittance and you get the really big money, when you and I are doing basically the same work?"

    The surgeon paused, smiled and leaned over, and whispered to the mechanic..... "Try doing it with the engine running!

I find it a bit spooky that a doctor would even need to look at old drawings to know how heart valves work. Isn't this why they are made to work on cadavers, so they know the body inside and out? Doesn't the real thing trump some old drawings?

It is likely that the heart surgeon could have made his discovery based on any other accurate drawing or illustration of the human heart, but d
