This paper presents an approach to modeling the closure of the mitral valve using patient-specific anatomical information derived from 3D transesophageal echocardiography (3D TEE). Our approach uses physics-based modeling to solve for the stationary configuration of the closed valve structure from the patient-specific open valve structure, which is recovered using a user-in-theloop, thin-tissue detector segmentation. The method utilizes a tensile shape finding approach based on energy

We tested the method using ten intraoperative 3D TEE sequences by comparing (a) the closed valve configuration predicted from the segmented open valve, with (b) the segmented closed valve, taken as ground truth. Experiments show promising results, with prediction errors on par with 3D TEE resolution and with good potential for applications in preoperative planning.
