Overview
Surgery is the mainstay of treatment for TGA. However, infusion of PGE1 to a newborn diagnosed with TGA is recommended as it prevents the ductus arteriosus from closing, therefore providing an additional shunt through which to provide the systemic circulation with a higher level of oxygen.
Medical Therapy
Surgery is the mainstay of treatment for TGA. However, infusion of PGE1 to a newborn diagnosed with TGA is recommended as it prevents the ductus arteriosus from closing, therefore providing an additional shunt through which to provide the systemic circulation with a higher level of oxygen.[1][2]
- Prostaglandins (PGE)
- Prevents the ductus arteriosus from closing, therefore providing an additional shunt through which to provide the systemic circulation with a higher level of oxygen.
- Antibiotics
- Antibiotics may be administered preventively. However, due to the physical strain caused by uncorrected d-TGA, as well as the potential for introduction of bacteria via arterial and central lines, infection is not uncommon in pre-operative patients.
- Diuretics
- Analgesics
- Analgesics normally are not used pre-operatively, but they may be used in certain cases. They are occasionally used partially for their sedative effects.
- Cardiac glycosides
- Cardiac glycosides are used to maintain proper heart rhythm while increasing the strength of each contraction.
- Sedatives
- Sedatives may be used palliatively to prevent a young child from thrashing about or pulling out any of their lines.
Life Style Modifications
Patients with transposition of the great arteries and a large ventricular septal defect who have not undergone repair may require certain life style modifications to control symptoms which include:
- Increased caloric density during infancy (particularly if they have significant congestive heart failure and poor weight gain).
- Following definitive repair, most patients do not need a special diet.
- Specific activity restrictions are dependent on the patient's residual hemodynamic abnormalities.
- Following the arterial switch procedure, exercise stress testing is necessary in older patients who are interested in participating in competitive sports.
