Introduction

Welcome to visibleheart.com, an interactive educational site creation jointly developed and maintained by the University of Minnesota and Medtronic, Inc.

This site is a showcase for the Visible Heart® project, a novel educational tool for observing how a real heart works from within. You can see a beating heart, all the valve movements, the contractions of atria and ventricles, and the architecture of the heart as it beats. The Video Library features video clips and sample views from various anatomical sites within the heart.

The Visible Heart® allows for visualization of the inner workings and anatomical features of a beating heart through the use of a clear blood-like solution and an isolated heart apparatus. The Visible Heart® preparation employed to produce such images as these on this website is subject to U.S. Patent No. 7,045,279. To view these images, visit the continually updated video library section of this site or follow the Visible Heart® throughout the world by clicking on the conferences section. You can also learn about the history of this project and the process by which these high-resolution images were created in the background section. However, the creation of internal images is only one facet of this multidisciplinary project. The Visible Heart® lab has published in peer-reviewed scientific journals on the merits of using an isolated large mammalian isolated heart maintained with a clear perfusate. The preparation can function in working or Langendorff modes for research in cardiac anesthesiology, cardiology, electrophysiology, and cardiac surgery. Additionally, this large mammalian isolated working heart also serves as a model for evaluating therapies targeted at improving cardiac performance following acute myocardial infarction, bypass and/or transplant procedures. After reviewing the contents of the site, send us your comments and/or requests for special educational programs where such images and associated functional data could be utilized, contact us to see if we can help.
