Tricuspid transcatheter valve-in-valve: an alternative for high-risk patients
(Oxford Univ Press Inc, 2012-03-01)
Tricuspid valve disease is not uncommon. Some patients with tricuspid valve disease require tricuspid replacement with bioprosthesis and, over time, may require re-interventions. Transcatheter tricuspid valve-in-valve ...
