Cardiac ultrasound shows that the left ventricular bright spot usually does not need treatment, usually with the growth and development of the fetus in the late pregnancy gradually disappear, the exact time can not be determined how long can completely disappear. Intraventricular bright spots and strong echoes in the left ventricle are ultrasound manifestations, which may be due to mineral deposits in the center of the papillary muscle, thickening of the tendon cords within the ventricle, or incomplete perforation of the papillary muscle, which are normal structural variation or transient manifestations, rather than pathologic changes. It usually does not require special treatment and will gradually become smaller and weaker as the fetus grows and develops, and mostly disappears in late pregnancy. In general, only less than 1% of the strong spots may suggest fetal chromosomal malformations or cardiac diseases. Therefore, cardiac ultrasound found that the left ventricle strong light spot but no other abnormalities, it is recommended to review the ultrasound regularly, usually pay attention to regular diet, strengthen nutrition, avoid colds, maintain a good state of mind, avoid emotional excitement, pay attention to rest, ensure adequate sleep, if other abnormalities are found, should be further examination, to clarify the presence of malformations.
