A general model for continuous noninvasive pulmonary artery pressure estimation
Elevated pulmonary artery pressure (PAP) is a significant healthcare risk. Continuous monitoring for patients with elevated PAP is crucial for effective treatment, yet the most accurate method is invasive and expensive, and cannot be performed repeatedly. Noninvasive methods exist but are somewhat inaccurate, expensive, and cannot be used for continuous monitoring. We present a machine learning...
متن کاملDOPPLER ECHOCARDIOGRAPHY Continuous - wave Doppler echocardiographic detection of pulmonary regurgitation and its application to noninvasive estimation of pulmonary artery pressure
Continuous-wave Doppler echocardiography was used to estimate pulmonary artery pressures by measuring pulmonary regurgitant flow velocity in 21 patients with pulmonary hypertension (mean pulmonary artery pressure 20 mm Hg) and 24 patients without pulmonary hypertension. The pulmonary regurgitant flow velocity patterns, characterized by a rapid rise in flow velocity immediately after closure of ...
متن کامل[Noninvasive, indirect measurement of pulmonary artery pressure].
OBJECTIVE The gold standard for measuring pulmonary artery pressure (PAP) is right heart catheterization. However, the usefulness of this technique is limited in patients with lung disease because of a poor acoustic window. The aim of this study was to assess PAP in a group of healthy persons using a noninvasive, indirect measurement procedure derived from the venous return flow velocity wave. ...
متن کاملEstimation of diastolic intraventricular pressure gradients by Doppler M-mode echocardiography.
Previous studies have shown that small intraventricular pressure gradients (IVPG) are important for efficient filling of the left ventricle (LV) and as a sensitive marker for ischemia. Unfortunately, there has previously been no way of measuring these noninvasively, severely limiting their research and clinical utility. Color Doppler M-mode (CMM) echocardiography provides a spatiotemporal veloc...
متن کاملAssessment of pulmonary artery pressure by echocardiography—A comprehensive review
Pulmonary hypertension is a pathological haemodynamic condition defined as an increase in mean pulmonary arterial pressure ≥ 25 mmHg at rest, assessed using gold standard investigation by right heart catheterisation. Pulmonary hypertension could be a complication of cardiac or pulmonary disease, or a primary disorder of small pulmonary arteries. Elevated pulmonary pressure (PAP) is associated w...
