35 weeks premature baby heart murmur is congenital heart disease

35 weeks premature infant heart murmur is not necessarily congenital heart disease.

For premature infants with congenital heart disease, due to the existence of pores between the heart chambers, abnormal growth of heart valves, local vascular stenosis, etc., it is easy to cause abnormal blood flow in the heart, heart murmur. However, there are many clinical reasons for premature infant heart murmur. The premature infant heart is not fully developed, resulting in blood turbulence in the heart vessels, and may also form physiological heart murmur. For premature infants who are invaded by external pathogens after birth and form diseases such as endocarditis and myocarditis, there may also be heart murmur.
