Pediatric Heart Conditions

We take specialized and evidence-based approaches to diagnose and treat pediatric heart conditions. The following is a list of heart conditions in children that our team of experts treats.

Loeys-Dietz Syndrome

A rare genetic disorder of the connective tissue, similar to Marfan Syndrome, affecting blood vessels, bones, joints, ligaments, and muscles, as well as internal organs.

Long QT Syndrome

A disorder causing abnormal heart rhythms, loss of circulation of blood through the heart and loss of consciousness, which can be fatal if not quickly controlled.

Marfan Syndrome

A condition that affects the entire body; specifically the connective tissues of the joints, eyes, heart, blood vessels, lungs, bones, and covering the brain and spinal cord.

Mitral Valve Prolapse

Caused when the left ventricle of the heart contracts, part of the valve falls back into the left atrium, allowing blood to leak back through the valve into the atrium.

Myocardial Bridging

A congenital anomaly in which the arteries that feed the muscles of the heart form inside the heart muscle instead of on the outer surface.


Inflammation of the heart muscle or of the lining outside the heart, the immune system causing inflammation to get rid of infection or in response to some other trigger.


An awareness of heartbeats, an uncomfortable but common complaint. A doctor can help determine if the palpitations are dangerous.

Patent Ductus Arteriosus

A tube-like connection between the aorta and pulmonary artery, which usually closes shortly after birth, but sometimes doesn't close, commonly in premature infants.

Postural Orthostatic Tachycardia Syndrome (POTS)

A chronic condition most often seen after the onset of puberty, usually indicated by the elevation of heart rate upon standing, causing dizziness and palpitations.

Pulmonary Stenosis

A pulmonary valve that doesn't open properly, causing the right ventricle of the heart to pump harder, restricting the amount of blood reaching the lungs for oxygenation.

Single Coronary Artery

A very rare congenital cardiac abnormality in which only one artery feeds blood to the heart muscle.

Single Ventricle

A complex congenital heart defect where only one ventricle, instead of two, has formed.
