Percutaneous temporary aortic valve: a hemodynamic support system for acute aortic insufficiency.

A percutaneous temporary aortic valve hemodynamic support catheter is a device that can conceptually maintain stable hemodynamics when significant structural damage occurs to the native aortic valve ensuing acute severe aortic insufficiency. Applications may include a bridge to surgery in active aortic valve endocarditis and an option to allow for diseased valve resection prior to transcatheter aortic valve replacement. An early prototype has undergone successful fundamental mathematical, bench and animal proof-of-concept studies. Design, concept and early data are presented and discussed.
