Congenital heart diseases

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

Congenital heart defects are heart malformations present at birth, meaning 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 anomaly
  • Hypoplastic left heart syndrome
  • Transposition of the great arteries
  • Patent ductus arteriosus
  • Pulmonary atresia
  • Valvular pulmonary stenosis
  • Single ventricle defects
  • Tetralogy of Fallot
  • Total anomalous pulmonary venous connection
  • Tricuspid atresia
  • Truncus arteriosus
  • Vetricular septal defect

 

What is the correct functioning of the heart?

The heart has four chambers. The two upper ones are the atria, the lower ones are the ventricles, and they are separated by a tissue wall called the pulp.

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

The four valves are:

  1. Tricuspid valve: It is located between the atrium and the ventricle on the right side.
  2. Pulmonary valve: it is located between the right ventricle and the pulmonary artery.
  3. Mitral valve: It is located between the left atrium and the left ventricle.
  4. Aortic valve: between the left ventricle and the aorta

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