What are the meanings of AO, LVD, LVS, LAS, RVD, RAS, PA, IVSD, LVPWD, MVE, TV, AOV, PAV, EF and FS in cardiac color ultrasound?

AO: the diameter of aorta; LVD: left ventricular inner diameter

LVS: end systolic inner diameter; LAS left atrial diameter

RVD: right ventricular diameter; RAS: right atrial diameter

PA: pulmonary artery diameter; IVSD: interventricular septum thickness

LVPWD: left ventricular posterior wall thickness; MVE: mitral valve orifice blood flow velocity

TV: tricuspid valve orifice blood flow velocity; AV: aortic orifice velocity

PV: pulmonary orifice velocity; EF: Ejection fraction

FS: Shortened fraction

Color Doppler echocardiography mainly checks whether there is any abnormality in the morphology of the heart and whether the heart function is normal, especially for congenital heart disease. Color Doppler echocardiography is the only instrument that can dynamically display the structure of the heart cavity, the beating of the heart and the blood flow, without any damage to the human body. The heart probe is like the lens of a camera. With the rotation of the probe, the various structures of the heart are clearly displayed on the screen.

Cardiac color Doppler ultrasound is also the only instrument that can directly display valve lesions. Through the measurement of color Doppler ultrasound, doctors can know the degree of valve lesions and decide whether to treat them conservatively or surgically. Cardiomyopathy is a disease with increasing incidence in recent years. The thickening of myocardium and the enlargement of cardiac cavity depend on color Doppler ultrasound to judge. For coronary heart disease, color Doppler ultrasound can directly display myocardial movement and cardiac function, and remind clinicians of the location of myocardial ischemia < P > Baidu Encyclopedia-Normal value of color Doppler ultrasound.
