Four chamber apical view with continuous wave Doppler interrogation across the tricuspid valve. The peak velocity is 2.7 m/sec, thus estimating a pressure gradient between the right ventricle and right atrium of 29 mmHg. This added to an RA pressure estimate will estimate PA systolic pressure. The high quality Doppler signal with a clearly defined peak lends to more reproducible and reliable pressure estimation.
