Heart Conditions


Myocarditis refers to an inflammation of the heart that usually results from an infection within the heart muscle itself. It is most often caused by a virus but can be caused by some bacteria (including the bacteria that causes Lyme Disease), fungi, autoimmune disorders like SLE (Systemic Lupus Erythematosis), and a host of medical drugs.

Prenatal care for aortic stenosis

In a normal fetus, blood flows from the heart through the aortic valve to the rest of the body. The term 'aortic stenosis' refers to a narrowing of this valve, resulting in an obstruction of blood flow. Advances in technology have led to increased ability to diagnose aortic stenosis in infants before birth. Fetal intervention to correct the anatomical defect has the potential to alter the natural history of the disease, which may lead to a significant improvement in the outcome.  

Prenatal Care for Hypoplastic Left Heart Syndrome

Hypoplastic left heart syndrome (HLHS) refers to the underdevelopment of the left side of the heart, including the aorta, aortic valve, mitral valve and the left ventricle. The hypoplastic left heart is unable to pump enough blood to meet the body's demands and requires surgery shortly after birth. 

Project ADAM

Project ADAM Michigan is a program administered by University of Michigan C.S. Mott Children’s Hospital Congenital Heart Center to help prepare schools for sudden cardiac emergencies. The Project ADAM initiative provides schools with guidance and support on how to minimize the risk of sudden cardiac death in the school setting.

Pulmonary Atresia

Pulmonary atresia (PA) is a rare congenital abnormality of heart development where the pulmonary valve that controls blood flow from the right side of the heart to the lungs doesn’t form (atresia).

Sick sinus syndrome

Sick sinus syndrome occurs when the sinus node — the heart’s normal pacemaker — does not function normally. Sick sinus syndrome is rare in young people except when there is a history of heart surgery involving the heart’s upper chambers — the atria.

Single Ventricle Clinic

The C.S. Mott Children’s Hospital Congenital Heart Center Multidisciplinary Single Ventricle Clinic provides comprehensive longitudinal evaluation and follow-up care for children, adolescents and young adults with single ventricle congenital heart disorders.

Sudden Cardiac Arrest Education Video Series

The U-M Cardiovascular Center and C.S. Mott Children’s Hospital have combined efforts to promote good cardiac screening practices by pediatric, family practice and school health care providers and to support emergency response readiness at local schools.

Supraventricular Tachycardia

Supraventricular tachycardia (SVT) is the most common arrhythmia (abnormal heart rhythm) diagnosed in children.

Tetralogy of Fallot

Tetralogy of Fallot occurs when the right side of the heart does not develop properly while a baby is in the mother's womb.

Three Strikes Congenital Heart Center

A young mother learns her unborn baby has a serious heart defect and may not survive to birth. By bringing her to the Congenital Heart Center at U-M's C.S. Mott Children's and Women's Hospital, the baby, Mira, not only survived to birth but continues to thrive.

Transposition of the Great Arteries

Complete transposition of the great arteries (TOGA) occurs when the aorta, which normally comes off the left ventricle and pumps red blood to the body, arises from the right ventricle(1) and pumps blue blood returning from the body back to the body bypassing the lungs completely.

Truncus Arteriosus

Truncus arteriosus occurs when the great arteries do not develop normally while the baby is in the mother’s womb.

Ventricular Fibrillation

Ventricular fibrillation (VF) is an arrhythmia (abnormal heart rhythm) that is rare in children. It can occur in children with cardiomyopathy, early after complex heart surgery, and very rarely in children with otherwise normal hearts.

Ventricular Septal Defect (VSD)

A ventricular septal defect (VSD) is a defect or hole(1) in the wall that separates the lower two chambers of the heart. These chambers are called the ventricles (2) and the wall separating them is called the ventricular septum. A child can have single or multiple ventricular septal defects. Ventricular septal defects also occur in association with more complex heart defects such as Tetralogy of Fallot and transposition of the great vessels. The information on this page applies to patients with a ventricular septal defect and an otherwise normal heart.

Ventricular Tachycardia

Ventricular tachycardia (VT) is an arrhythmia (abnormal heart rhythm) that is quite rare in children. It can occur in children with cardiomyopathy, following some heart surgeries, and with inherited diseases that affect the heart’s electrical system (e.g. Long QT syndrome, Brugada’s syndrome).

Wolff-Parkinson-White syndrome

Wolff-Parkinson-White syndrome is a congenital heart problem that affects the heart’s electrical system. Although it is present at birth, the onset of symptoms varies and indeed some people never have symptoms.
