Tricuspid stenosis is a rare condition, whereas tricuspid regurgitation is more frequent, especially in its secondary form. For appropriate management, secondary tricuspid regurgitation has to be clearly distinguished from primary tricuspid regurgitation. Similar to mitral regurgitation, primary tricuspid regurgitation requires intervention sufficiently early to avoid secondary damage of the RV, which is associated with poor outcome. Secondary tricuspid regurgitation should be liberally treated at the time of left-sided valve surgery. Consideration of isolated surgery of secondary tricuspid regurgitation after previous left-sided valve surgery requires comprehensive assessment of the underlying disease, pulmonary haemodynamics, and RV function.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
