Congenital heart defects

  1. 1. Congenital Heart Defects  
  2. 2. What are Congenital Heart Defects? <ul><li>Congenital Heart Defects are problems with the </li></ul><ul><li>heart's structure that are present at birth. These </li></ul><ul><li>defects can involve: </li></ul><ul><ul><li>The interior walls of the heart  </li></ul></ul><ul><ul><li>The valves inside the heart  </li></ul></ul><ul><ul><li>The arteries and veins that carry blood to the heart or the body  </li></ul></ul>
  3. 3. Congenital Heart Defects
  4. 4. Sign and Symptoms Signs and symptoms are related to the type and Severity of the heart defect.   
  5. 5. Embryology There is a complex sequence of events that result in a well   formed heart at burth and disruption of any portion may result in   a defect.The orderly timing of cell growth,cell migration,and   programmed cell death (&quot;apoptosis&quot;) has been studied      extensively and the genes that control the process are being     clearing up.
  6. 6. Changes at Birth  The ductus arteriosus stays open because of circulating   factors including prostaglandins. The foramen ovale stays   open because of the flow of blood from the right atrium to   the left atrium.  
  7. 7. Causes   The cause of congenital heart disease may be either genetic or environmental, but is usually a combination of both.
  8. 8. Genetics <ul><li>Most of the known causes of congenital heart disease are sporadic genetic changes, either focal mutations or deletion or addition of segments of DNA.  </li></ul><ul><li>  </li></ul>
  9. 9. Prepregnancy and Maternal Obesity Several studies have shown an increased risk for neural tube defects associated with prepregnancy maternal obesity. Because few recent studies have examined the relation between maternal prepregnancy obesity and overweight and other birth defects, we explored the relation for several birth defects and compared our findings with those of previous studies.
  10. 10. Hypoplasia <ul><li>Hypoplasia can affect the heart, typically resulting in the underdevelopment of the right ventricle or the left ventricle . This results in only one side of the heart capable of pumping blood to the body and lungs effectively.Hypoplasia of the heart is rare but is the most serious form of CHD. It is called hyperplasia left heart syndrome  when it affects the left side of the heart and hyperplasia left heart syndrome  when it affects the right side of the heart. </li></ul><ul><li>  </li></ul>
  11. 11. Obstruction defects and Septal defects <ul><li>  </li></ul><ul><ul><li>OBSTRUCTION DEFECTS </li></ul></ul><ul><ul><li>  SEPTAL DEFECTS </li></ul></ul>Obstruction defects occur when heart valves, arteries, or veins are abnormal narrow or blocked.Common defects include pilmonic stenosis,aortic stenosis,and coarctation of the aorta,with other types such as bicuspid aortic valve stenosis and subaortic stenosis being relative manner rare. The septum is a wall of tissue which separates the left heart from the right heart . Defects in the interatrial septum  or the interventricular septum allow blood to flow from the left side of the heart  the right, reducing the heart's efficiency. Ventricular septal defects are
