Abstract
In patients with isolated severe tricuspid regurgitation (TR), the degree of mitral regurgitation (MR) tends to be masked. Right ventricular (RV) dilation and dysfunction following chronic TR promote left ventricular (LV) underfilling and limit MR. After stand-alone tricuspid valve (TV) surgery, MR can progress as the reduced LV preload is restored.1 In mitral valve (MV) surgery, even if TR is not severe, TV surgery is recommended if the TV annulus increases to a certain level or in the presence of moderate TR.
