Cardiac valve modeling

Abstract

The aim is to provide plans, solutions, concepts, designs, methods, and systems related to representing the predicted length of heart valve leaflets. This can be achieved by obtaining both a 3D model representing the geometric shape of the heart valve leaflets and the predicted length of the heart valve leaflets. The 3D model can then be adapted based on the predicted length to generate an adapted 3D model representing the extension of the heart valve leaflets to the predicted length.
