Da Vinci clue for heart surgeon

It appears that Leonardo Da Vinci is helping with modern heart surgery.

Leonardo worked out in the 1500s that the opening phase of the mitral valve was extremely important - this can be compromised with conventional surgery because the opening is made narrower than normal.

Mr Wells says he can now repair the floppy mitral valve in such a way that it does not alter the normal diameter of the valve when it is open which means that the individual can return to more vigorous exercise without any problems.

He said Leonardo had a depth of appreciation of the anatomy and physiology of the body - its structure and function - that perhaps has been overlooked by some.
