❚❚ POURQUOI ESTIMER LA PRESSION DE
L’OREILLETTE DROITE (POD)?
L’estimation de la PAPS à partir du ***flux Doppler continu d’insuffisance
tricuspide (IT)*** est incontestablement la méthode le
plus souvent et le plus facilement réalisable à partir d’incidences
différentes (parasternale, apicale, sous-costale).

Continuous wave (CW) Doppler of the tricuspid regurgitation (TR) trace is used to measure the difference in pressures between the right ventricle and right atrium. The simplified Bernoulli equation (P = 4[TRmax]2) is used to

Background: ***Tricuspid regurgitation velocity (TRV)*** as a surrogate for invasive mean pulmonary artery pressure (mPAP) is integral in the assessment of pulmonary hypertension (PHT).

To quantify pulmonary hypertension with echocardiography it is necessary to measure the ***maximal tricuspid regurgitation velocity with CW Doppler***. Thus, pulmonary pressures can be obtained only in the presence of a measurable TR signal. Fortunately, a certain degree of tricuspid regurgitation is frequently observed, and ...
