Differentiating L-transposition of the great arteries from other Disease
Patients with tricuspid atresia should be differentiated from other cardiac and non-cardiac causes of cyanosis-
Cardiac causes (starts with ‘t’)-
- Tetralogy of Fallot
- Truncus arteriosus
- Total anomalous pulmonary venous connection
- Other tricuspid valve abnormalities like tricuspid regurgitaton, tricuspid stenosis
Other less common causes are- pulmonary atresia, hypoplastic left heart syndrome, anomalous systemic venous connection.
Non-cardiac causes
- Pulmonary diseases – Structural abnormalities of the lung, V/P (ventilation-perfusion mismatch), airway obstruction, pneumothorax, and hypoventilation.
- Abnormal hemoglobin like methemoglobin, polycythemia
- Peripheral cyanosis for e.g. sepsis, hypoglycemia, dehydration, and hypoadrenalism.
