Ventricular septal defect symptoms?

summary

Ventricular septal defect (VSD) is a new problem for ordinary people. But if we are careless about it, the consequences will be serious. In order to better understand the disease, let's take a look at the following introduction.

Ventricular septal defect symptoms?

Children with small defects are asymptomatic and usually have an unexpected cardiac murmur during physical examination. The children have normal growth and development, ruddy complexion and flexible reaction. There was no abnormality of chest wall, normal size of left ventricle and no abnormality of peripheral blood vessel pulsation.

The main signs were as follows: there was a loud systolic murmur on the left lower edge of sternum, often accompanied by tremor, and most of the murmurs were full systolic; In the case of infraarterial defect, murmur and tremor were limited to the left upper sternal margin. For small muscle defects, the murmur is characterized by a short and high pitched systolic murmur at the left lower edge of the sternum. The murmur is terminated in the middle of contraction due to the narrowing or sealing of the holes between the trabeculae during myocardial contraction. There is no direct relationship between the intensity of cardiac murmur and the size of ventricular septal defect.

Children often have clinical manifestations when the pulmonary circulation resistance decreases 1-2 months after birth. Due to large pulmonary circulation flow, pulmonary edema, increased pulmonary venous pressure, decreased lung compliance, sucking difficulty, fatigue and sweating during feeding, weight loss, delayed height development, shortness of breath, repeated respiratory tract infection, further aggravating the formation of heart failure.

matters needing attention

The whole systolic murmur was weakened or even disappeared, and a loud systolic ejection murmur could be reached at the left upper edge of sternum. Aortic valve prolapse can lead to aortic regurgitation. Due to the increase of left ventricular end diastolic volume, there may be flood pulse, apical beat outward and characteristic diastolic blowing murmur of left sternal border hyperthyroidism. There is a loud and rough systolic murmur between the third and fourth ribs on the left edge of sternum. X-ray and ECG examination shows left ventricular enlargement and other changes. Combined with no cyanosis and other clinical manifestations, the disease should be suspected first. General two-dimensional and color Doppler ultrasound can be a clear diagnosis.
