b'10 A N O T H E R F I R S T New technique resolves leaky heart valve HonorHealth was the first site in Arizona to perform a transcatheter tricuspid valve replacement on a patient outside of a clinical trial. In this advanced technique an artificial, self-expanding tricuspid valve is implanted via a catheter to prevent or reduce tricuspid regurgitation, the backflow of blood into the upper right chamber of the heart.When this condition becomes moderate or severe, it can be life limiting and potentially, life threatening.12 HonorHealth Foundation'
