If your physician or healthcare provider detects a heart murmur and recommends follow-up tests, he or she may be concerned about the possibility of a valve problem. Although some heart murmurs indicate heart valve problems, many heart murmurs are considered to be “innocent” or harmless.
Your baby came to the cardiologist for evaluation of a heart murmur and the doctor tells you that your newborn has mild PPS, peripheral pulmonary stenosis. Then they tell you that this is a common finding in newborn babies and that you shouldn't worry.
Aortic stenosis is one of the most common and most serious valve disease problems. Aortic stenosis is a narrowing of the aortic valve opening. Aortic stenosis restricts the blood flow from the left ventricle to the aorta and may also affect the pressure in the left atrium.
A cervical venous hum is an extremely common type of innocent heart murmur. It is caused by the sound of blood flow returning normally through the veins above the heart. Specifically, the jugular veins drain blood from the head and neck and connect to larger veins which return to the heart.
