![]() ![]() Cyanosis happens when an infant or child’s skin turns blue from lack of oxygen during activity, such as crying or feeding.Īnother heart problem that causes a murmur is patent ductus arteriosus, in which a connection between the aorta and the pulmonary artery fails to close correctly after birth. This is a set of four defects in the heart that lead to episodes of cyanosis. One of the more serious congenital problems that causes heart murmurs is called Tetralogy of Fallot. These can be benign and never cause symptoms, or they can be severe malformations that require surgery or even a heart transplant. Murmurs, especially in children, may be caused by congenital heart malformations. Problems with these parts of your heart may lead to unusual sounds that your doctor can detect by listening to your heart with a stethoscope or by performing an echocardiogram test. Your pericardial sac surrounds your heart and protects it. The aortic valve goes from your left ventricle to your aorta.The pulmonary valve goes from your right ventricle out to your pulmonary trunk.The mitral valve leads from your left atrium to your left ventricle.The tricuspid valve goes from your right atrium to your right ventricle.They make sure that your blood always flows in one direction. Valves are located between these chambers. The two upper chambers are called the atria, and the two lower chambers are called the ventricles. What are the causes of heart murmurs and other sounds? A rubbing sound is usually caused by an infection in your pericardium (a sac that surrounds your heart) due to a virus, bacteria, or fungus. ![]() Rubbing sounds may be heard in people with certain kinds of infections. This can cause some regurgitation of blood into your left atrium. This could indicate a mitral valve prolapse, when one or both flaps of your mitral valve are too long. Other soundsĬlicks or short, high-pitched sounds may also be heard during your regular heartbeat. This is called a “summation gallop,” which can occur when your heart is beating very fast. You can also have both an S3 and an S4 sound. It’s always a sign of disease, likely the failure of the left ventricle of your heart.
