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. 

Filter by Condition

Anomalous Left Coronary Artery Arising from the Pulmonary Artery (ALCAPA)

Anomalous left coronary artery arising from the pulmonary artery (ALCAPA) is a rare pediatric heart condition that Lurie Children’s treats.

Aortic Stenosis

When the aortic valve is narrowed or thickened, causes obstruction. This makes it hard for the heart to pump blood to the body.

Aortopathy (Dilated Root & Abnormalities of the Aorta)

Any disease of the aorta, the main artery taking oxygenated blood from the left side of the heart to the arteries of all limbs and organs.

Arrhythmias & Electrophysiology

Arrhythmia is an abnormal rhythm of the heart. Learn more about pediatric arrhythmias including causes, symptoms, treatment, and electrophysiology here.

Arrhythmogenic Right Ventricular Cardiomyopathy (ARVC)

ARVC is a rare, heart condition linked to sudden death. We’re experts at genetic diagnosis and treatment for children and families with ARVC.

Arterial Tortuosity Syndrome

A rare disease affecting the connective tissue of the body, causing abnormal twists and turns in the arteries.

Atrial Septal Defect

An opening between the heart's two upper chambers, which lets some blood from the left atrium return to the right atrium instead of flowing to the body.

Atrioventricular Canal

When the common valve between the upper and lower chambers doesn't close properly, allowing blood to leak backward from the heart's lower chambers to the upper ones.


Cardiomyopathy can appear suddenly (acute) or can be present for many years or even since birth (chronic/congenital), and can lead to heart failure. Learn more here.

Catecholaminergic Polymorphic Ventricular Tachycardia (CPVT)

CPVT is a rare heart condition linked to rhythm problems and sudden death. We’re experts at genetic diagnosis and treating children and families with CPVT.

Chest Pain

Chest pain in children and teenagers is most commonly musculoskeletal, pulmonary, or idiopathic. It is rarely due to cardiac disease. Learn more about here.

Coarctation of the Aorta

When the aorta is pinched or constricted, usually between the upper and lower half of the body, obstructing blood flow to the lower part and increasing blood pressure in the upper.
