There is no definitive answer to the chances of a ventricular septal defect healing on its own, and it is specifically related to the size of the defect. Small ventricular septal defects are usually asymptomatic and are often detected on physical examination when a rough holosystolic murmur is heard below the left edge of the sternum. Medium- and large-sized defects can present with symptoms in the late neonatal period and infancy, such as difficulty in feeding, shortness of breath when sucking on the breast, pallor, excessive sweating, lack of weight gain, recurrent respiratory infections, and congestive heart failure that often occurs in the first six months of life. Ventricular septal defect belongs to a kind of congenital heart disease. Ventricular septal defect has a certain possibility of self-healing with age, you can go to the hospital through the ultrasound examination of the heart, and if it is found that there is no self-healing, it can be treated by surgery, so as not to affect the growth and development of the child. Specific diagnosis and treatment need to follow the doctor’s advice.
