Tricuspid Regurgitation

Tricuspid regurgitation is a fairly common lesion in the 21st century, likely due to the large number of patients who are surviving longer after bouts of endocarditis, pulmonary hypertension, severe left heart disease, etc.
The murmur is usually soft, heard along the lower left sternal border, and gets louder with inspiration (Carvallo’s sign).
