Abstract
In this review, we discuss right-sided heart valve disease, namely tricuspid regurgitation (TR), tricuspid stenosis, pulmonary regurgitation, pulmonary stenosis and right-sided endocarditis. These are frequently seen in conjunction with other diseases, making assessment of their significance more difficult, but it has become increasingly clear that moderate or severe right-sided heart valve disease, in particular TR, is associated with worse prognosis. There remain large gaps in our knowledge of medical and interventional treatment, but in this article we outline what is known about the causes, presentation and management of these commonly seen conditions.
