How can you make a TR get more prominent during Doppler echo?

A tricuspid regurgitation (TR) jet can be enhanced by deep inspiration or passive leg raising which increases the right sided inflow. Another method is to give agitated saline used for contrast echo, which also makes the TR jet more prominent. Sometimes it is possible to enhance TR jets by adjusting the gain and reject settings of the echocardiograph.
