Comer Children's Hospital cardiologists and cardiac surgeons are experts in the diagnosis and treatment of heart valve conditions. Our patients are our priority; we take time to get to know each family, understand the cause and severity of each child's condition, explain our diagnostic process, and answer any questions you may have about heart valve conditions.
The heart consists of four chambers, two atria (upper chambers) and two ventricles (lower chambers). Valves serve as gatekeepers, allowing blood to leave each chamber of the heart while preventing it from flowing backward. There are four heart valves: the tricuspid valve, pulmonary valve, mitral valve and aortic valve. Common heart valve conditions include:
- Regurgitation, which occurs when the valve doesn't close completely, allowing blood to flow backward into the heart
- Stenosis, or valve narrowing, which prevents the heart from properly distributing blood to the body
- Atresia, or undeveloped valves, which prevents blood from passing between the atria and ventricles
