Transluminal implantation of artificial heart valves. Description of a new expandable aortic valve and initial results with implantation by catheter technique in closed chest pigs.

Andersen and colleagues invented percutaneous aortic valve replacement (PAVR), also known as percutaneous aortic valve implantation (PAVI), transcatheter aortic valve implantation (TAVI) or transcatheter aortic valve replacement (TAVR). This procedure replaces the aortic valve of the heart through the blood vessels, instead of by open heart surgery.  See Andersen, H.R. "How transcatheter aortic valve implantation (TAVI) was born: The struggle for a new invention," Cardiovasc. Med., 29 September 2021 | https://doi.org/10.3389/fcvm.2021.722693.
