Correlation between Pulmonary Artery Pressure Measured by Echocardiography and Right Heart Catheterization in Patients with Rheumatic Mitral Valve Stenosis (A Prospective Study)

.

Sensitivity and specificity of sPAPTRVmax in detecting pulmonary hypertension (PH) were 92.8% and 86.6% .

.

Atenção à técnica:

RAP was estimated to be 3 mmHg when the IVC diameter was <21 mm with >50% collapsibility, 8 mmHg when the IVC diameter was <21 mm with <50% collapsibility, and 15 mmHg when the IVC diameter was >21 mm with <50% collapsibility.

Vejam agora como usar corretamente a aceleração do fluxo na pulmonar:

mPAPPAAT: Pulsed-wave Doppler interrogation of the proximal PA was then performed in the parasternal short-axis view with the sample volume placed at the annulus of the pulmonary valve. The sample volume was placed at the pulmonary valve annulus and not more proximally in the RV outflow tract to maximally align blood flow and Doppler interrogation. PAAT was defined as the interval between the onset of systolic PA flow and peak flow velocity, whereby mPAPPAAT = 79 − (0.45 × PAAT). In cases with PAATs < 120 ms, the following formula was used: 90 − (0.62 × PAAT).

.

Vejam a sensibilidade a simples análise do fluxo na pulmonar:

mPAPPAAT were 94.1% and 73.3%,

.

Então, soltar laudo sem estimativa da pressão pulmonar passa a ser proibido nas boas casas do ramo de ecocardiografia
