Hola Juan Sebastian!

Perhaps this paper could be of help for you:

Harper WF (1983). The blood supply of heart valves in relation to endocarditis. J Anat., 73(Pt 1):94-111 [PMCID: PMC1252531].

http://www.ncbi.nlm.nih.gov/pmc/articles/PMC1252531/

Gennady Taradin

Dear Dr. Acevedo,

There is some more new publication concerning this question.

Article Prediction of Oxygen Distribution in Aortic Valve Leaflet Co...

James Pate

The two papers above are good. Harper's paper is a classic. Having studied dozens of valves, microscopically, I never saw blood vessels within the substance of the leaflet of NORMAL valves. It appears that inflammed valves develop neovascularity just as in other "granulation" tissues.
