Jan 22, 2025 · Pulmonary artery acceleration time (PAAT) and PAAT–to–right ventricular ejection time ratio (PAAT:RVET), by pulsed-wave Doppler echocardiography, are markers for pulmonary artery pressures.

Jun 20, 2022 · Pulmonary artery acceleration time (PAAT) has emerged as reliable parameter for the estimation of systolic pulmonary artery pressure (sPAP) in cardiological population with preserved right ventricular function.

Pulmonary artery acceleration time (PAAT) is a non-invasive method to assess pulmonary hemodynamics, but lacks validity in children. This study sought to evaluate the accuracy of Doppler echocardiography (DE) derived PAAT in predicting right heart ...

Dec 21, 2016 · Pulsed-wave Doppler determination of the pulmonary artery acceleration time (PAAT) as a surrogate for pulmonary artery pressure was found to be of clinical value for assessment of pulmonary hypertension (PH) with studies to date exclusively performed in adults.

Doppler measurements of the pulmonary artery accel- eration time (PAAT) are commonly used to estimate pulmonary artery pressure (PAP).

Pulmonary artery acceleration time (PAAT) is a reliable and non-invasive method for assessing pulmonary hemodynamics. To date, few studies have used PAAT to assess preterm infants, especially those with respiratory distress syndrome (RDS).

Apr 15, 2018 · PAAT measurement. PAAT measured in (A) upper esophageal aortic arch short-axis view and (B) midesophageal ascending aortic short-axis view in a patient with atrial fibrillation. PAAT was measured from onset of systolic pulmonary artery flow to peak velocity using pulsed-wave Doppler.

The aim of this study was to determine whether echocardiography-derived pulmonary artery acceleration time (PAAT) possesses adequate diagnostic performance for PH, using right-heart catheterization as a reference standard.

Pulmonary Artery Doppler Waveform Parameter known as Pulmonary Artery Acceleration Time (PAAT) has been investigated in adults and older children and found to be reliable in estimating pulmonary pressure.

Doppler echocardiography (DE) derived Pulmonary Artery Acceleration Time (PAAT) is a non-invasive method to assess and longitudinal track changes in pulmonary hemodynamics, but lacks validity in children.
