Patient's question:
22-week ultrasound showed a strong echo spot in the left ventricle of the fetus. Below is the full report: Fetal heart: The four-chamber view clearly shows that the sizes of the left and right atria and ventricles are almost symmetrical, the connections between the left and right atria and ventricles are consistent, the central "cross" intersection exists in the heart, the mitral valve and tricuspid valve are clear, and the opening and closing movements are visible on both sides. The outflow tracts of the left and right ventricles are clear, the relationship between the ventricles and the great arteries is consistent, and the great arteries are cross-arranged at the base of the heart. A strong echo spot is visible in the left ventricle of the fetus.I asked the doctor who performed the examination today, and she said that a screening for Down syndrome is needed. If the test results are normal, this is no
Doctor's answer:
Left ventricular intracardiac strong echo is an ultrasound finding, not a cardiac malformation, nor a diagnosis of fetal cardiac abnormalities. It is very common in clinical practice, and its pathogenesis remains unclear. There are several possible explanations:1. Central mineralization of papillary muscles
2. Thickening of intraventricular chordae
3. Incomplete perforation of papillary muscles and chordae (a developmental variation). Intracardiac strong echoes are generally of no significant clinical importance for most fetuses but can also be seen in fetuses with other cardiac and extracardiac abnormalities. Down syndrome is low-risk, which means it’s okay.
