Patient's question:
Heart position and connections are normal. Right atrium and right ventricle are enlarged. Myocardial activity is normal. Pulmonary artery is widened. There is a 1.4 cm by 1.3 cm atrial septal defect with 11 holes (located 0.7 cm from the superior vena cava, 1.4 cm from the inferior margin, 1.0 cm from the right upper pulmonary vein, and 0.65 cm from the mitral valve). Left-to-right low-speed shunt.Doctor's answer:
Hello, ventricular septal defect is caused by incomplete development of the septum during the embryonic period, making it the most common congenital heart disease. It can be classified into three types: small ventricular septal defect, with a defect diameter less than 5 millimeters; medium ventricular septal defect, with a diameter of approximately 5 to 10 millimeters; and large ventricular septal defect, with a diameter greater than 10 millimeters. If the defect is small, it may be asymptomatic, and the child's general activities are not restricted, with normal growth and development. If the defect is larger, the child often exhibits delayed growth and poor weight gain.
