Description

MIVAL3D: A MULTIDISPLINARY PROJECT OF SEHRC ON MITRAL VALVE SURGERY E-LEARNING.

Mitral valve insufficiency is the second heart valve disease in the first world, and it frequently requires surgical treatment. These surgery procedures require a high level of expertise and pre-surgery thorough evaluation of different strategies for the intervention. Although modern heart imaging such as 3D echocardiography provides a good insight into heart structures, there is a lack of specific tools for surgeons to visually analyze heart structures, simulate different surgical approaches and predict function changes after the intervention.

The aim of the MIVAL3D project was to create a set of tools based on medical imaging to allow surgeons to visually analyze and interactively manipulate a 3D model of the patient's heart, simulate a surgical intervention procedure and predict functional changes after the intervention.

Phase I of the project developed a virtual recreation tool to:  (i) reconstruct a 3D graphic model of the heart from two- and three-dimensional echocardiographic images, (ii) segment its different structures and extract a polygonal model of the left ventricle and the mitral valve, (iii) perform a quantitative analysis of the mitral valve motion in normal physiological conditions and (iv) construct a synthetic reference virtual model of the heart that to use as a reference atlas model.

Using the application, surgeons can select a dataset of a particular patient or a reference model, analyze it on the basis of illustrative visualizations that clearly distinguish the segmented structures, and, at the same time, provide enough realism. Moreover, they can query for a blood flow simulation that takes into account the topological and geometrical model of the mitral valve and the left ventricle, the blood pressures and the  mechanical properties of the heart tissues. The results of this simulation are shown as an animation on top of the heart model. Finally, they can graphically define a surgery approach and query for the modified model animation.
