In the past, it was assumed that correcting aortic or mitral valve disease would reduce tricuspid regurgitation. This assumption has historically kept the volume of tricuspid repair and replacement procedures relatively low. While the volume of tricuspid replacement procedures has remained low in recent years, the volume of tricuspid repair procedures has increased strongly. The increase in tricuspid repair procedures has been pushed by a growing awareness among cardiologists of the hazards of leaving severe tricuspid regurgitation untreated. The volume of tricuspid replacement procedures has remained low due to the lower mortality rates associated with tricuspid repair relative to replacement.
