Multiple bright spots in the left ventricle, usually seen in fetal ultrasound, are an ultrasound phenomenon, not a reflection of cardiac malformations or abnormalities, but a normal developmental phenomenon, and most of the bright spots will disappear with the increase of months. The macules are graded by the ultrasound display of the bone tissue, which is graded in three levels, one below the bone tissue, two below the bone tissue, and three above the bone tissue. It is generally considered to be a thickening of the left ventricular papillary muscle, tendon cords, and calcification of mineral deposits within the papillary muscle. It cannot be fully elucidated at this time and is normal, but requires good periodic review. In addition, with the increase of age, myocardial tissue will deposit calcification, in the ultrasound examination will appear strong spot, this strong spot mostly belongs to the degenerative changes, usually does not affect the cardiac structure and function, but there are some will lead to valvular calcification, valvular closure insufficiency, this situation should be regularly observed.
