Chest X-ray: On chest X-ray (CXR), transposition of the great vessels typically shows a cardio-mediastinal silhouette appearing as an "egg on a string", in which the enlarged heart represents an egg on its side and the narrowed, atrophic thymus of the superior mediastinum represents the string. [4]
[2] [3] Chest x-rays and electrocardiograms may also be used in reaching or confirming a diagnosis; however, an x-ray may appear normal immediately following birth. [2] [3] If d-TGA is accompanied by both a VSD and pulmonary stenosis, a systolic murmur will be present. [citation needed]
Chest X-ray: X-ray images help to visualize the condition of the lungs and heart. If the heart is enlarged on an X-ray, other tests will usually be needed to find the cause. A useful measurement on X-ray is the cardio-thoracic ratio, which is the transverse diameter of the heart, compared with that of the thoracic cage. [30]
A chest radiograph, chest X-ray (CXR), or chest film is a projection radiograph of the chest used to diagnose conditions affecting the chest, its contents, and nearby structures. Chest radiographs are the most common film taken in medicine.
Simple l-TGA does not produce any visually identifiable features at birth. However, systemic blood pressure then becomes much higher than pulmonary blood pressure. The morphological right ventricle, evolved to handle a low blood pressure, will over a period of years hypertrophy and may fail, because of the high pressure it is forced to work against.
Arterial switch operation (ASO) or arterial switch, is an open heart surgical procedure used to correct dextro-transposition of the great arteries (d-TGA). [ 1 ] [ 2 ] Its development was pioneered by Canadian cardiac surgeon William Mustard and it was named for Brazilian cardiac surgeon Adib Jatene , who was the first to use it successfully.
By comparison, a chest X-ray carries a dose of approximately 0.02-0.2 mSv [10] and natural background radiation exposure is around 2.3 mSv/year. [11] Thus, each cardiac CT scan carried out with current protocols (dose approximately 1 mSv) is equivalent to approximately 5-50 chest X-rays or less than 1 year of background radiation.
