Patient: Pediatric patient with heart murmur. Laboratory, examination date: 03/19/08 left atrium slightly large, remaining atrium of normal size, normal wall thickness, regular motion, normal amplitude of motion, continuous and intact atrial septum, 5 mm echogenic interruption in the myocardial part of the septum near the intercardium. normal opening and closing of all valve structures, normal internal diameter of ascending aorta and pulmonary artery. There were no abnormal channels between the aorta and no pericardial effusion. CDFI: abnormal periseptal blood flow was seen in systole from the left ventricle into the right ventricle through the septal defect orifice, the blood flow bundle was not dominated by red, colorful mosaic, Vmax=3.8m/s, PG=58mmHg, TDI-PW: motion velocity spectrum at the septal mitral annulus S wave V=6.8cm/s, E wave V=8.7cm/s, A Doctor’s orders: review after 6 months, would like to hear your opinion. Guangzhou Children’s Hospital Cardiac Center Zhang Li: Myocardial ventricular septal defect usually cannot heal by itself, your child’s defect is 5mm, which is a small to moderate defect, plus it is a myocardial ventricular defect, which does not have a great impact on hemodynamics, I don’t know if your child usually has symptoms such as recurrent colds or pneumonia, if not, you can consider surgery or interventional treatment when you are older, and review every three to six months.
