Cœur en sabot
Cœur en sabot is a radiological sign seen most commonly in patients with tetralogy of Fallot, a cyanotic congenital heart disease. It is a radiological term to describe the following findings in the x-ray:
- The cardiac size is normal or mildly enlarged.
- The left cardiac border shows uplifted apex "outermost lower most point of the heart at the left side" denoting right ventricular enlargement.
- exaggerated cardiac waist, which means that the pulmonary segment is small and concave suggesting infundibular pulmonary stenosis.
