Patient: 4.5 year old girl with normal valve morphology and motility: no significant thickening of the myocardial echogenicity: the middle of the ventricular septum was dilated towards the right ventricle. CDFI recorded a left-to-right shunt with a shunt velocity of 390 cm/sec and a pressure difference of 61 MMHG. A small notch, approximately 0.36 cm wide, with normal septal continuity and no shunt in the septal plane or in the pulmonary artery was seen. The pressure difference was 23 MMHG, and a limited regurgitation was recorded in the pulmonary valve with an area of 0.3 cm2. The impression is that the heart chambers are normal in size: septal membrane tumor combined with small ventricular defect: tricuspid valve, pulmonary valve with limited regurgitation. What is the prognosis? Thank you for the detailed answer! Doctor: Analysis: The diagnosis of ventricular defect is clear, the fractional flow is not large, and it should have little effect on growth and development and daily activities. In the future there may be problems: 1, a few people may suffer from infective endocarditis, causing sepsis; 2, the presence of a heart murmur has an impact on further education and employment, etc. Treatment recommendations: 1, the first choice of surgery. Reason: mature technology, long-term efficacy is certain, there are fifty years of treatment history 2, follow-up observation, every few years should review the ultrasound, any problems immediately to seek medical attention. 3, interventional treatment is not recommended Structurally less suitable, long-term efficacy is not certain, complications are not uncommon.
