The murmur of tricuspid regurgitation is best heard at the lower sternal border, and classically increases significantly when more blood is returned to the right side of the heart with inspiration. Patients with tricuspid valve regurgitation will have a flow rumble due to increased flow through the tricuspid valve. The flow rumble is best heard at the lower sternal border and increases with inspiration.
Tricuspid valve regurgitation results in a large V-wave in the jugular venous pulse. As regurgitation becomes more severe, the normal X-trough is obliterated and there may be a single, positive CV wave detected. If the patient is in atrial fibrillation only a CV wave is observed since an A-wave is dependent upon atrial systole and sinus rhythm. The V-wave of tricuspid regurgitation increases in height during inspiration.
