The strong left ventricular spot is usually found without any special treatment, and continued observation is sufficient. Fetuses are often found to have a strong left ventricular spot on ultrasound. 99% of the spots get smaller and disappear with increasing gestational age, while only less than 1% of the spots indicate chromosomal abnormalities or cardiac malformations. Therefore, it is of special clinical significance to find strong light spots in fetal heart ultrasound, especially if the spot is less than 5 mm. Therefore, if the fetus is found to have a strong light spot in the left ventricle and there are no positive findings in other laboratory tests of the pregnant woman, there is generally no need to deal with it, and regular review of the cardiac ultrasound is sufficient. If other abnormalities are found, further tests are recommended to clarify the possibility of malformation. In adults, the presence of strong light spots in the left ventricle is usually indicative of calcification. If the patient has symptoms of discomfort, further tests such as coronary CT and coronary angiography can be performed to clarify the diagnosis.
