NCT01627964

Brief Summary

The study develops software for motion analysis and assessment of cardiac function for cardiac images. Cardiac catheterization ventriculography of several randomly selected patients were taken from our hospital's PACS system. The investigators remove the patient information on the images, and use the image for motion analysis and assessment.
