Description de la mesure |
Délai |
|---|---|---|
|
Pulmonary artery pressure (PAP) assessment - Tricuspid valve regurgitation peak velocity
Délai: up to 72 hours
|
This is measured in apical 4 chamber view, with continuous wave Doppler using modified Bernoulli equation. Systolic pulmonary artery pressure is equivalent to right ventricular systolic pressure in absence of outflow obstruction. Systolic Pulmonary Artery Pressure (SPAP) = Right Ventricular Systolic Pressure = 4x TR2 + Right Atrial Pressure (RAP) (RAP= 3-5 mmHg) |
up to 72 hours
|
|
Pulmonary artery pressure (PAP) assessment - Pulmonary regurgitation peak velocity
Délai: up to 72 hours
|
This is measured in short axis parasternal view with continuous wave Doppler using this equation: Mean Pulmonary Artery Pressure MPAP= 4xPR2 + Right Ventricular Diastolic Pressure (RVdP=2-5 mmHg)
|
up to 72 hours
|
|
Pulmonary artery pressure (PAP) assessment - Transductal right-to-left flow peak velocity
Délai: up to 72 hours
|
This is measured in high short axis ductal view with continuous wave Doppler
|
up to 72 hours
|
|
Pulmonary artery pressure (PAP) assessment - Interventricular septum configuration
Délai: up to 72 hours
|
This is measured in short axis parasternal view above level of papillary muscles, left ventricle is normally O shaped, D or crescent shape indicated bowing of septum due to RV dysfunction.
|
up to 72 hours
|
|
Pulmonary artery pressure (PAP) assessment - Left ventricle systolic eccentricity index (LV-sEI)
Délai: up to 72 hours
|
This is measured in short axis parasternal view by measuring LV dimensions the parallel versus the perpendicular dimension.
The normal ratio is 1.
|
up to 72 hours
|
|
Right ventricular performance - Tricuspid annular plane systolic excursion(TAPSE)
Délai: up to 72 hours
|
This is measured using Mmode in apical 4 chamber view over lateral annulus of tricuspid valve
|
up to 72 hours
|
|
Right ventricular performance - Myocardial Performance Index (MPI)
Délai: up to 72 hours
|
This is measured by using pulsed wave doppler to measure isovolumetric ejection time + isovolumetric relaxation time/ right ventricular ejection time.
|
up to 72 hours
|
|
Right ventricular performance - E/A ratio
Délai: up to 72 hours
|
This is measured in apical 4 chamber view by pulsed wave Doppler on mitral valve.
The cut off value: 0.8- 2.
|
up to 72 hours
|
|
Left ventricular performance - Ejection fraction
Délai: up to 72 hours
|
This is measured using M-Mode in long axis parasternal view with a normal range of 55-75%
|
up to 72 hours
|
|
Left ventricular performance - E/A ratio
Délai: up to 72 hours
|
This is measured in apical 4 chamber view by pulsed wave Doppler on mitral valve.
The cut off value: 0.8- 2
