An atrioventricular canal defect, or AV canal, is a combination of several closely associated heart problems that result in a large defect in the center of the heart.
Cardiac catheterization is a specialized procedure in which a long, flexible tube — a catheter — is inserted into a vein or artery and guided into the heart.
Cardiovascular genetic testing helps determine if a change in your child’s DNA explains the features of their heart anatomy or their risk for a cardiac condition seen in your family.
Catecholaminergic polymorphic ventricular tachycardia (CPVT) is an inherited cardiac condition that causes sudden rhythm disturbances in otherwise healthy children.
A fetal cardiac intervention (FCI) is a needle- and catheter-based procedure guided by an ultrasound image that can help improve some life-threatening heart problems in a fetus.
Hemitruncus is when one pulmonary artery branch arises from the ascending aorta just above the aortic sinuses, whereas the main pulmonary artery and the other pulmonary branch arise in their...
Hypertension (high blood pressure) refers to how hard the blood is pushing against the walls of the artery through which it flows — not how quickly it flows.
A single ventricle defect occurs when one of the two pumping chambers in the heart, called ventricles, isn’t large enough or strong enough to work correctly.
Tetralogy of Fallot (TOF) is a serious congenital heart defect where the heart’s anatomy prevents enough oxygen-poor (blue) blood from flowing to the lungs to receive oxygen.
Tetralogy of Fallot (TOF) with pulmonary atresia is a more severe form of TOF, where the heart’s anatomy prevents enough oxygen-poor (blue) blood from flowing to the lungs to receive...
Transesophageal echocardiography uses a small ultrasound probe placed into a child’s esophagus to closely evaluate the heart and blood vessels within the chest.
Transposition of the great arteries (TGA) is when the “great” arteries, the aorta and the right ventricle, are reversed in their origins from the heart.
In tricuspid atresia, the tricuspid valve — which is normally located between the right atrium and the right ventricle — is missing, as is the right ventricle.
Twin reversed arterial perfusion (TRAP) occurs in identical twin pregnancies when one twin has an absent or non-functioning heart and receives all of its blood from the normally functioning and...
