Chest X-Ray
Chest x-ray findings of left atrial enlargement are:
- Double density sign: Occur when the right side of the left atrium pushes behind the right atrial border, appearing as a double density. If large enough it can actually reach beyond the border of the right atrium.
- Convex left atria appendage: usually reflect prior rheumatic heart disease
- Splaying of the carina
- Posterior displacement of the left main stem bronchus on lateral radiograph
- Superior displacement of the left main stem bronchus on frontal view
- Posterior displacement of a barium filled oesophagus or nasogastric tube
