Stent treatment of inferior vena cava compression in an ovine with a total artificial heart

Artif Organs. 2011 Jul;35(7):E161-3. doi: 10.1111/j.1525-1594.2011.01233.x. Epub 2011 May 25.


Although current continuous-flow total artificial hearts (CFTAHs) are much smaller than previous models, venous kinking may still occur after device implantation, especially in smaller animals. By inserting a self-expanding stent at the site of venous narrowing in a sheep model implanted with a CFTAH, we were able to restore the normal venous geometry and dramatically increase the CFTAH output. Because this percutaneous approach avoids the challenges associated with reoperation in these cases, it may be useful to other CFTAH investigators.
