Outcomes After Transcatheter Mitral Valve Intervention: Threatened by Tricuspid Regurgitation

The tricuspid valve (TV) was historically referred to as the forgotten valve and considered to be a passive structure, on the systemic venous side of the heart, without clinically significant function. However, recent studies showed all-cause mortality was higher for tricuspid regurgitation (TR) than for aortic-valve disease or mitral-valve disease (hazard ratios: 2.74, 1.62, 1.25 respectively).1 TR is classified into primary, secondary or implantable device related. Primary tricuspid regurgitation occurs because of intrinsic valve disease and is attributable to congenital anomalies, infective endocarditis, rheumatic disease, carcinoid heart disease, toxic effects of chemicals, tumors, blunt trauma, or myxomatous degeneration.
