Congenital Heart Defects

Cardiovascular diseases are considered the leading cause of death in the world.

Congenital heart defects are problems with the structure of the heart present from birth, which means that the heart or blood vessels did not develop properly.

There are different types of congenital heart disease, such as

  • Aortic Valve Stenosis
  • Atrial Septal Defect
  • Coarctation of the Aorta
  • Complete Atrioventricular Canal Defect
  • Transposition of the Great Arteries
  • Ebstein’s Anomaly
  • Hypoplastic Left Heart Syndrome
  • Patent Ductus Arteriosus
  • Pulmonary Atresia
  • Pulmonary Valve Stenosis
  • Single Ventricle Anomalies
  • Tetralogy of Fallot
  • Total Anomalous Pulmonary Venous Connection
  • Tricuspid Atresia
  • Truncus Arteriosus
  • Ventricular Septal Defect

What is the correct functioning of the heart?

The heart has four chambers. The upper two are called the atria, the lower two are called the ventricles, and are separated by a wall of tissue called the atrial septum.

Blood is pumped through the chambers, passing through the four valves, which open and close to allow passage in one direction only.

The four valves are:

  • Tricuspid valve-This is located between the atrium and the ventricle on the right side.
  • Pulmonary valve-This is located between the right ventricle and the pulmonary artery.
  • Mitral valve-This is located between the left atrium and left ventricle.
  • Aortic valve – located between the left ventricle and the aorta.

Normal blood flow is a cycle that flows like this: body-heart-lungs-heart-body.

If you have a heart condition, contact the ABC Cardiovascular Center to schedule an appointment with a specialist who can treat your specific symptoms.
