Key result
A patient-specific fluid-structure interaction model successfully reproduced mitral valve mechanics and estimated a regurgitant volume of 60 ml, matching clinical imaging findings.
Why the study?
Patient-specific computational models of the mitral valve could provide a personalised understanding of mitral valve mechanics, dysfunctions, and possible interventions.

This proof-of-concept study demonstrates that integrating advanced imaging with computational fluid-structure interaction models can successfully simulate patient-specific mitral valve mechanics, paving the way for personalized treatment planning.
Patient-specific mitral models merit prospective validation; leaves open any role in guiding therapy.
The mechanics of the mitral valve (MV) are the result of the interaction of different anatomical structures complexly arranged within the left heart (LH), with the blood flow. MV structure abnormalities might cause valve regurgitation which in turn can lead to heart failure. Patient-specific computational models of the MV could provide a personalised understanding of MV mechanics, dysfunctions and possible interventions. In this study, we propose a semi-automatic pipeline for MV modelling based on the integration of state-of-the-art medical imaging, i.e. cardiac magnetic resonance (CMR) and 3D transoesophageal-echocardiogram (TOE) with fluid-structure interaction (FSI) simulations. An FSI model of a patient with MV regurgitation was implemented using the finite element (FE) method and smoothed particle hydrodynamics (SPH). Our study showed the feasibility of combining image information and computer simulations to reproduce patient-specific MV mechanics as seen on medical images, and the potential for efficient in-silico studies of MV disease, personalised treatments and device design.

Biffi et al. (2019) conducted a case report in Mitral regurgitation (n=1). Patient-specific fluid-structure interaction (FSI) modeling vs. Clinical imaging (CMR and TOE) was evaluated on Mitral valve regurgitant volume. A patient-specific fluid-structure interaction model successfully reproduced mitral valve mechanics and estimated a regurgitant volume of 60 ml, matching clinical imaging findings.
