Overview

A x-ray may be employed in the diagnosis of patients presenting with palpitation when there is an increased suspicion of structural heart disease.

X Ray

• A x-ray may be employed in the diagnosis of patients presenting with palpitations when there is an increased suspicion of structural heart disease.
• These include conditions such as :
  1. Mitral Valve Prolapse
  2. Severe aortic regurgitation
  3. Severe mitral regurgitation
  4. Congenital heart diseases
  5. Mechanical prosthetic valves
  6. Hypertrophic cardiomyopathy

Severe Mitral Regurgitation

• Chest x-ray demonstrates cardiomegaly with features of left atrial enlargement (double contour on the right, splayed carina and enlarged left atrial auricle). The heart is also generally enlarged as are the pulmonary veins, particularly in the right upper zone.
• The rough outline of the left atrium (yellow) can be inferred by the presence of a double border on the right (green arrow), splaying of the carina (blue) and prominence of the left atrial appendage (red arrow).

Prosthetic Heart Valves

• Mitral valve replacement and cardiac pacemaker following AVSD repair with BCPC (bidirectional cavo-pulmonary connection).

Atrial Septal Defect

• Cardiac contour is at the upper limit of normal for size.
• The aortic arch is small, and the pulmonary trunk prominent, consistent with the previous history of atrial septal defect.
• Lungs and pleural spaces are clear. No pneumothorax shown. No displaced fracture.
