Left ventricle of the maternal heart 9 years after pregnancy

Anatomy of the left ventricle LV of 153 mothers 5-10 years after pregnancy, with and without a history of hypertension The LV end diastolic anatomy was reconstructed from the contours using high order interpolation meshes as described in our previous work. The 153 meshes were then spatially aligned by their centre of mass, and by an orientation defined by their basal plane and the left to right direction set by the centre of mass of the LV and right ventricle. A statistical shape model was then built with a principal component analysis (PCA), finding the modes of anatomical variation of this cohort. Data shared containts:1. AtlasMeshData.zip, where each case has 1.1 binary.vtk: The mask of the left ventricular (LV) myocardium and right ventricular blood pool from the short axis magnetic resonance image in end diastole1.2 binary_mesh files (.exelem and .exnode): the cubic Hermite mesh that was personalised to the anatomy of the left ventricle1.3 Image_binary_mesh.jpg: image of the overlay between the fitted mesh and the mask of the LV myocardium1.4 Image_Initialization.jpg: image of the overlay between the template LV mesh used for personalization and the mask of the LV myocardium1.5 ImageDistances2ClosestPointbinary_meshxxxxxxxxxx.jpg: image of the distances between the LV mesh and the mask of the LV myocardium (xxxxxxxxxx is a digit encodign for the time when the image was generated)1.6 PersonalizationReportbinary.txt: file with metrics of mesh fitting accuracy and quality 2. VTKMeshes.zip: the collection of all the LV shapes in VTK format, after correction of centre of mass and circumferential orientation. 3. AtlasModesPVSn43_rvspace_s4_c3.pdf: illustration of all the 10 first modes of anatomical variation, together with the box-plot of the differences between hypertensive pregnancy (blue) and normotensive pregnancy (green). 4. Mode6revealsDifferences.png: screen capture of mode 6 from last file, revealing the largest differences between the groups of hypertensive and normotensive pregnancy.
