Cardiovascular Model Repository

The geometric models in this repository are collected from past research projects in the Cardiovascular Biomechanics Research Laboratory at Stanford University. The geometric models in this repository are mostly built from imaging data of healthy and diseased individuals. For each of the models, a short description is given with a reference. Click on the model image for a larger image of the model. The geometric models are in VTK PolyData XML .vtp format. For information about this format see VTK.org.You are free to download the geometric models and use them provided that you properly reference the source. The models are part of the academic output of the researcher cited and should be referred to as such. Permission is granted to use these models for research purposes, but not for commercial use.<b>Note: This repository is no longer maintained. A more up-to-date repository of cardiovascular models can be found at http://www.vascularmodel.com/sandbox/doku.php. </b> <br/><br/>This project includes the following software/data packages: <br/> <ul> <li> <a href="https://simtk.org/frs?group_id=31#pack_104">Arteriofemoral_bypass </a> : A 67 year-old female with rest pain and calf claudication at 20 feet with a past medical history significant for peripheral vascular disease (ankle brachial index 0.50 bilaterally), chronic obstructive pulmonary disease, nicotine abuse, and cerebral vascular occlusive disease (60% carotid stenosis) was studied. Noninvasive imaging was consistent with atherosclerotic occlusive disease of the iliac and femoral arteries bilaterally. Imaging data was acquired preoperatively to obtain geometric information (using MRA) of the aorto- iliac-femoral system. Approximately two weeks after the acquisition of the preoperative data the patient underwent an end-to-side aorto-femoral reconstruction. A Dacron bypass graft with nominal dimensions of 14 mm x 7 mm was used. Postoperative image data was acquired approximately 6 months after the operation. </li> <li> <a href="https://simtk.org/frs?group_id=31#pack_102">Bypass </a> : This model of a stenosis with a bypass is created from in-vitro MRI. </li> <li> <a href="https://simtk.org/frs?group_id=31#pack_106">Healthy3 </a> : Model of the sub-thoracic aorta including the iliacs from a healthy volunteer. </li> <li> <a href="https://simtk.org/frs?group_id=31#pack_105">Palmaz-stent </a> : The geometry of this stent is built using standard dimensions available in literature. The geometry is similar to a five-ring Palmaz-Schatz stent. The expanded geometry is taken from a pressure-driven expansion using a large-displacement, large-strain, elasto-plastic analysis using ABAQUS. </li> <li> <a href="https://simtk.org/frs?group_id=31#pack_101">Patient1 </a> : A 67 year-old male with bilateral aneurysms of the common iliac arteries. Note the tortoisity of the iliac arteries and the four renal arteries. </li> <li> <a href="https://simtk.org/frs?group_id=31#pack_285">Virtual Aorta 1 </a> : This model is constructed using two different datasets from two different subjects; one dataset of the thoracic aorta and one dataset of the the abdominal aorta including some parts of the iliacs. The solid models from the two datasets are scaled and modified to obtain a reasonably accurate solid model of the full aorta. </li> </ul>
