Good.
I believe that at for the moment (we can talk about looking at images later) you, Prasanna, and I (puts a community surgeon like me in pretty good company) agree about the need for emphasis on proper diagnosis. We "gave" that away (did we ever have it, Bob?), but the emphasis is SURGICAL diagnosis, not "MR", "bad ventricle with EF 30%, etc. We would never(?) argue to operate on just a description of 3 vessel disease.
But the point I wish to take up with you, Ani, was your comment to the effect: it is not the right surgeon for the patient, but the right patient for the surgeon. This to me seems nonsense in our usual "test tube surgery" limitations of appropriate conversation. (WARNING! Here goes tea again and pretty soon we will have to pull Mitch and Bill off each other again.)
In the surgery test tube we mix valve surgeon and patient with valve. Which ever goes in first and however it goes in we get repaired valve. For the sake of argument we all now agree that this is better than the tube with nonvalve surgeon and valve patient. (Forget my subpopulation dissent, and other possible ingredients.)
My question for you, and we are now completely out of our safe experimental and artifical test tube, is how do we best get to that mixture in the test tube? Without getting "personal and ideological" (even if in actuality it is the only way we get there so I will talk in formalisms) do we restrict the options for surgeons and likely in parallel patients to prohibit bad mixtures, or do we seek to open up and incent the likelyhood that more surgeons will meet the valve that they can fix?
When I hear the name Stark or listen to you and Hal talk about "limiting" those that would do valves, I get the sense that you push for "pure ingredients" hoping for better mixtures even if it may mean less suitable but workable mixtures might be denied. Or do we "incent" low volume surgeons and perhaps low volume programs with better diagnosis to aim over time for ultimately more total numbers of repaired valves? My favorite option is the latter. Both of us would have all kind of qualifiers, exceptions, etc, to our model, but which way is it? Do we limit or expand? It seems a simple choice on the surface. It may, however, be a choice for destiny. (Did I say we create our craft more than discover it?)
As you know I like analogies from other areas so I propose two different ones for thought. Over time would you have more money (or repaired valves) if you charged a nominally higher flat interest rate, or would it be better to accept a lower rate up front that can be compounded? If that seems difficult to rethink would you rather have a higher inital rate of valve repair or more surgeons trying to repair valves?
Secondly, historically monoarchy and communism seem to argue for completely opposite mechanisms for a benevolent society. One wanted to direct the "just" from above, the other secure the "just" from below. (One, perhaps both, were a lie, but I give the benefit of the doubt when at all possible. Don, you pick the liar.) Either of these systems at times and circumstances could have or did suceed just like the choice of a good and not bad flat interest rate. Both, however, seem to have failed. Why? I think because both lagged over time from other imperfect systems that leveraged the small compounds of the many.

Tea
My chief's (Dr Adams) main focus is not intraoperative differentiation but pre-operative differentiation of disease based on history and imaging. We wrote a paper on this in the current issue of seminars. We would *never* counsel a patient referred for mitral surgery without first reviewing the echocardiographic image usually we review these images with the patients as I am sure you do with CMR. Only after review of these images do we make a statement about repairability, choice of procedure, incisions, potential durability of repair and alternative therapies. It is not enough - indeed it is hardly helpful - to look at an echo report.
I do agree with your focus on pre-operative imaging. I spend more and more time reviewing cardiac CTs and MR images with our imaging cardiologist - it surprises me more or more what one can see. It is also important as you say for master surgeons to demistify their disciplines - part of the problem with low uptake of mitral repair, aortic valve repair etc comes I believe because those who thrive in it often over-mystify it.

If the surgeon studies the echo and is not sure he can repair it, he is the wrong surgeon for the patient. That patient should seek a surgeon who looking at the echo stands a good chance of repairing it. The days of 'discovering' in the operating room that a valve is not repairable should be over - this assertion should have been made on the pre-operative echo and either the patient told by the surgeon *preoperatively* that the best he or she can do is replace the valve or the patient
should be sent to another surgeon with expertise in valve reconstruction. I have seen many patients with Barlow's during my training scheduled for a 'mitral valve repair' and yet predictably (because the entire team knows the surgeon would never repair such valves) end up with a replacement with a long story to the> cardiologist on how tough a valve it was and how it cannot be repaired. > > We should not be making intuitive decisions in front of mitral insufficiency in the OR anymore - these should be made pre-operative on the transthoracic (or transesophageal if done) echocardiogram. In this era it should no longer be an excuse for a mitral valve replacement that the surgeon thought a replacement was the best approach 'in his hands' - those were the wrong hands for this patient and the patient should never have got there in the first place. In an elective case, if a valve is indeed to be deemed irreparable, that final determination should ideally only
be made by valve experts like Hal and Prassana, or at least by the most experienced valve surgeon assessible to that patient, to give patients the maximum probability of achieving a repair.> > We have an editorial coming out soon in JTCVS discussing this.> > Ani> > > > > > From: battr at medizin.uni-leipzig.de> To: OpenHeart-L at lists.hsforum.com> Subject: AW: [HSF] redo mitral video nope> Date: Wed, 24 Oct 2007 11:33:10 +0200> CC: > > Ani,> You theorized all the points, also Tea, but do not forget that moving the> instruments there is a SURGEON with more or less experience E.g.
