Mayo Clinic cardiology fellow, Erin Fender, M.D., discusses secondary tricuspid regurgitation as well as the epidemiology, survival, and long-term outcomes. Visit here for more information on tricuspid regurgitation at Mayo Clinic.
The causes of secondary tricuspid regurgitation can fall into two different categories, pressure overload lesions and right ventricular and annular dilation. Pressure overload lesions include left ventricular systolic dysfunction, diastolic dysfunction, pulmonary hypertension, and mitral or aortic valve disease. Right ventricular dilation and annular dilation include dilated cardiomyopathy, atrial fibrillation, right ventricular infarction, and left to right shunt. Surgical options are available for tricuspid regurgitation repair, however, early intervention is important.
