What’s wrong?

• The aorta arises from the right ventricle and pumps 'blue' blood to the body, head and limbs causing child to be cyanosed hence urgent intervention is required.
• Must have one or more of other defects such as ASD,VSD,PDA in order to survive prior to surgery.

Corrective Procedures?

• If ASD/PFO is inadequate - Balloon Atrial Septostomy is done shortly after birth - echo guided procedure which can be done in ICU or in the cath lab.
• Surgical Correction is performed usually within 4 weeks of life.
  
  
  • Arterial switch operation- switching of great vessels to correct pumping chambers (ventricles) and re-implantation of coronary arteries to newly constructed aorta.

What are the possible complications after the procedures?

• Chest is usually left opened for 2-3 days to allow swelling in the heart to subside and usually closed in PICU.
• Bleeding as the operation involves numerous suture lines
• Arrhythmias
• Ventricular dysfunction
• Coronary artery insufficiency
• Pulmonary Artery narrowing a few years after surgery
