	Introduction

 
Historically, right-sided valvular disease has received less attention from clinicians and researchers than left-sided valve disease, in part because of a protracted latent asymptomatic period. Moreover, because tricuspid regurgitation (TR) is often due to left-sided valve disease and pulmonary regurgitation (PR) is often secondary to congenital cardiac disease, the underlying disorder rather than the valve lesion tends to dominate the clinical picture.

It is increasingly recognized that right-sided valve disease is not benign and has a significant and independent impact on morbidity and mortality. Today, diagnostic techniques and appropriate management strategies for patients with right-sided valve disease are established and continually refined. In this era of increasing awareness and improved treatment options for patients with valve disease, it is important that clinicians consider the diagnosis of right-sided valve disease, understand its pathophysiology, choose appropriate confirmatory testing, and refer patients for timely intervention to prevent clinical deterioration with associated adverse consequences.

This review examines the causes of right-sided valve disease and the latest diagnostic advances and treatment options for these often-neglected valve lesions. Patients with native right-sided valve disease are rarely affected by endocarditis, and indications for prophylaxis have recently changed.¹

	Tricuspid Valve Disease

 
Tricuspid Regurgitation
TR that is at least moderate in severity is most frequently "functional" in nature and by definition not related to primary tricuspid valve (TV) leaflet pathology but rather secondary to another disease process causing right ventricular (RV) dilatation, distortion of the subvalvular apparatus, tricuspid annular dilatation, or a combination of these. Furthermore, a moderate or greater degree of TR, regardless . . . [Full Text of this Article]
