The murmur of tricuspid regurgitation is characterized on auscultation by a soft, blowing wind-like sound that intensifies on inspiration, usually below grade 3/6. Tricuspid regurgitant murmurs and instrumental murmurs are extremely rare. Most tricuspid regurgitation is caused by relative tricuspid valve insufficiency due to right ventricular enlargement, commonly due to chronic obstructive pulmonary disease leading to pulmonary hypertension, resulting in right heart failure, which causes right ventricular enlargement leading to dilatation of the valve annulus, causing relative tricuspid regurgitation. Acute tricuspid regurgitant murmurs can be seen in acute pulmonary embolism leading to acute right heart failure, causing a regurgitant tricuspid murmur. For the presence of tricuspid regurgitant murmur, the main treatment is to actively treat the underlying disease causing pulmonary hypertension and right heart failure, and no special treatment is needed for tricuspid regurgitation.
