What we do
About our project
Congenital heart disease is the most common birth defect with an estimated incidence of 1 in 100 live birth. Among many reported congenital defects, univentricular heart defects represent the most severe end of the spectrum, in which most commonly one ventricle is severely underdeveloped and thereby unable to drive the systemic or pulmonary circulation. Even though many surgical approaches have been proposed and applied resulting in increased life-expectancy, patients with congenital cardiovascular disease can still suffer from long-term complications related to the local biomechanical stress. Therefore, studies on the influence of biomechanical stress on local geometrical adaptations can potentially inform treatment and surgery strategies.
In our studies we make use of imaging and image based modeling to assess local biomechanical parameters in for instance the Fontan circulation or in the ascending aorta in patients born with bicuspid valves. For these studies MRI imaging is often used either to derive directly hemodynamic parameters, including flow or shear stress or as input parameter for computational fluid dynamics to quantify for instance power loss, viscous energy loss or stagnation volume. Longitudinal image and data acquisition are applied to link these biomechanical parameters to outcome in these patients.
