PValves for

From Cat in a Bowl Design:

PValves is an extensible database for compiling "normal" prosthetic heart valve hemodynamic values. A core database is included but it is, and will probably always be, a work in progress. PValves is freeware but is more accurately "reference-ware". The plan is for users to make available to everyone any additions they make to the database and useful references they come across, sort of along the lines of the open source model.
