Computational cardiac modeling based on transesophageal echocardiographic imaging

Researchers demonstrated the design of a biomechanical model of the left ventricle complex to assist in virtual surgery and pre-operative surgical planning. The researchers specifically focused on the problem of hemodynamic computational modeling in the left heart complex and the recovery of an anatomical model of the valve and left heart chambers. The main feature of the approach involved the exploitation of prior patient-specific data resulting from image analysis of transesophageal echocardiographic (TEE) imagery. The approach recovered kinematic and anatomical information in the form of left heart chambers and valve boundary through a level-set-based user-in-the-loop segmentation on 2-D and 3-D TEE.
