Innocent heart murmurs are caused by blood flowing through the chambers and valves of the heart or the blood vessels near the heart. Sometimes anxiety , stress , fever , anemia, overactive thyroid, and pregnancy will cause innocent murmurs that ca...

Many children have heart murmurs that are heard by their doctors at some time in their lives. Innocent heart murmurs are caused by blood flowing faster than normal through the chambers and valves of the heart or the blood vessels near the heart. A...

Mitral valve prolapse is a heart problem in which the valve that separates the upper and lower chambers of the left side of the heart does not close properly.
|
 |
Mitral valve prolapse (MVP) is a ballooning of the support structures of the mitral heart valve into the left upper collection chamber of the heart.

Ventricular septal defect describes one or more holes in the wall that separates the right and left ventricles of the heart. Ventricular septal defect is one of the most common congenital (present from birth) heart defects. It may occur by itself ...
|
 |
A ventricular septal defect is a hole in the wall of the heart (septum) that separates the left lower chamber (left ventricle) from the right lower chamber (right ventricle). The hole allows blood to flow from the left ventricle to the right ventr...

Patent ductus arteriosus (PDA) is a condition in which a blood vessel called the ductus arteriosus fails to close normally in an infant soon after birth. (The word "patent" means open) The condition leads to abnormal blood flow between the aorta a...

 |
Patent ductus arteriosus (PDA) is a heart defect that occurs when the ductus arteriosus (the temporary fetal blood vessel that connects the aorta and the pulmonary artery) does not close at birth.
|

Patent ductus arteriosus (PDA) is a heart abnormality that occurs when the ductus arteriosus (the temporary fetal blood vessel that connects the aorta and the pulmonary artery) does not close at birth.

Patent ductus arteriosus (PDA) is a heart abnormality that occurs when the ductus arteriosus (the temporary fetal blood vessel that connects the aorta and the pulmonary artery) does not close at birth.

The aorta is the main artery leaving the heart. When blood leaves the heart, it flows from the lower chamber (the left ventricle), through the aortic valve, into the aorta. In aortic stenosis, the aortic valve does not open fully. This restricts b...
|
|
When aortic valve stenosis occurs, the aortic valve, located between the aorta and left ventricle of the heart, is narrower than normal size.
|
|
|
Pulmonary valve stenosis is a condition in which the flow of blood from the heart (right ventricle, or lower chamber) is blocked at the valve that separates the heart from the pulmonary artery (pulmonic valve. This narrowing is usually present at ...
|
|
Pulmonary valve stenosis is a congenital heart defect in which blood flow from the heart to the pulmonary artery is blocked.
|
|
|
Atrial septal defect (ASD) is a congenital heart defect in which the wall that separates the upper heart chambers (atria) does not close completely. Congenital means the defect is present at birth.
|
|
An atrial septal defect is an abnormal opening in the wall separating the left and right upper chambers (atria) of the heart.
|
 |
An atrial septal defect (ASD) is an abnormal opening in the muscular wall separating the left and right upper chambers (atria) of the heart.

 |
Aortic coarctation is a narrowing of part of the aorta (the major artery leading out of the heart. It is a type of birth defect. Coarctation means narrowing.
|
|
Coarctation of the aorta (COA) is a congenital heart defect that develops in the fetus. It involves a constricture of the aorta, the main artery that delivers blood from the left ventricle of the heart to the rest of the body. In a constricture or...
|
|
A defect that develops in the fetus in which there is a narrowing of the aortic arch, the main blood artery that delivers blood from the left ventricle of the heart to the rest of the body. Coarctation of the aorta is diagnosed in both newborns an...

Acute mitral regurgitation is a disorder in which the heart's mitral valve suddenly does not close properly, causing blood to flow backward (leak) into the upper heart chamber when the left lower heart chamber contracts. See also: Chronic mitral r...

|
Chronic mitral regurgitation is a long-term disorder in which the heart's mitral valve does not close properly, causing blood to flow backward (leak) into the upper heart chamber when the left lower heart chamber contracts. The condition is progre...
