The use of the hepatic pressure maneuver to identify the murmur of tricuspid regurgitation.

To enhance the bedside diagnosis of tricuspid regurgitation, the influence of manual pressure applied below the liver on lower left sternal border murmurs was determined in 23 patients. All 23 subjects had right ventriculograms and right atrial phonocardiograms. The sign was positive in 13 cases, including 3 who were without a Carvallo sign. The application of manual pressure below the liver is a simple and valid additional maneuver for identifying the murmur of tricuspid regurgitation.
