Measurement of atrioventricular annular plane displacement has been revived: will it prove to be useful in assessing fetal cardiac function?

摘要

The history of recording atrioventricular (AV) annular motion using ultrasound can be traced back to the 1960s1. The first papers describing the feasibility of recording mitral annular motion using M-mode ultrasonography and demonstrating that these recordings are distinctly different from those of the mitral valve leaflets, and instead resemble left ventricular volume curves, were published in 19672'3. Furthermore, it was found that the amplitude of mitral annular plane systolic excursion (MAPSE) correlated with stroke volume and was reduced in patients with heart failure3. However, these important observations were somehow forgotten and the technique has not been popular among cardiologists, who mostly prefer using the ejection fraction (EF) to assess systolic ventricular function.
