On ultrasound, myocardial echo enhancement in the upper and middle segments of the left ventricular inferior wall is usually not serious. It is not a cause for concern in the average adult, and the echo enhancement may be related to poor lifestyle habits. In contrast, it may be more serious in those with congenital cardiac insufficiency. In the case of simple fetal echogenic enhancement of the upper and middle segments of the lower wall of the left ventricle, most of it is due to thickening of the tendon cords in the heart or calcification of the papillary muscle, which is a normal physiological phenomenon. With the increase of gestation months and the growth and development of the fetus, these phenomena will disappear automatically and there is no need to worry too much. If you are still unsure, it is recommended that you go to the hospital for a complete cardiovascular examination to determine the cause of the disease, and actively cooperate with the doctor’s diagnosis and relevant treatment.
