AW: [HSF] redo mitral video nope

I think we have to take this to the next level and move on from advocating the right operation for the right surgeon to advocating the right surgeon for the right patient. 

Prasanna made this quite clear - as a surgeon you should be able to tell with near certainty on examining a pre-op TTE whether you can repair a mitral valve. 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.
