Tracheobronchial calcification: an observation in three children after mitral valve replacement and warfarin sodium
1Department of Radiology, Children's Hospital Medical Center, Oakland, CA.
Insights
Warfarin sodium therapy may cause tracheal calcification in children, particularly after heart valve surgery. Further research is needed to confirm this link in pediatric patients.
Area of Science:
- Pediatric Cardiology
- Radiology
- Pharmacology
Background:
- Tracheal calcification in children can be congenital or acquired.
- Calcification in the larynx and trachea is a known complication of warfarin embryopathy.
Abstract:
Tracheal calcification in children may be congenital or acquired. The authors describe three children in whom tracheal or tracheobronchial calcification was noted on radiographs after prosthetic mitral valve replacement and after long periods of warfarin sodium therapy. Laryngeal and tracheal calcification has been known to occur in warfarin embryopathy. This suggests that possibility of warfarin sodium as an etiologic factor in the development of the tracheal or tracheobronchial calcification in these children. However, further investigation is necessary.

Definition and Purpose
An X-ray, or radiograph, is a non-invasive method that uses ionizing radiation to take images of internal structures. It is mainly used in cardiac imaging to examine the heart, lungs, and major blood vessels, aiming to identify abnormalities in the heart's size, shape, and position, such as heart failure, congenital defects, and vascular...
