It is not possible to generalize how long it usually takes for a fetal left ventricular strong spot to disappear; some fetuses may disappear around 28 weeks and some fetuses will not disappear.
Fetal left ventricular bright spot is an imaging description of a strong echogenic spot similar in intensity to the echoes of bone observed on ultrasound near the papillary muscle or tendon cords in the cavity of the left ventricle of the fetus.
The timing of the disappearance of the fetal left ventricular strong spot depends on the cause of the disease. Strong echoes caused by incomplete perforation of the tendon cords of the papillary muscles of the fetal heart usually close gradually, and in some fetuses they disappear gradually after 28 weeks of gestation.
Fetal chromosomal abnormalities caused by the left ventricle strong spot, generally can not gradually become smaller, on the contrary, may gradually increase, to further improve the amniocentesis, non-invasive DNA and other tests, to clarify the presence or absence of chromosomal abnormalities, the condition is more serious, the termination of pregnancy should be carried out under the guidance of a doctor.
After pregnancy, we should do a good job of maternity examination during pregnancy, and any abnormalities should be dealt with in a timely manner.
