Abstract

We present new algorithms to compute patient specific strain maps for mitral valve leaflets, by tracking and modeling deformations of the mitral valve apparatus in 3D echocardiography. We can then quantify comparisons of mitral leaflets strain maps between normal patients and cases of mitral valve prolapse or regurgitation. For patients with mitral valve regurgitation, we compare mitral leaflets strain maps between pre-surgery and post-surgery, to quantify the strain reduction due to mitral valve repair surgery.
