Cœur en sabot

Cœur en sabot (French for "clog-shaped heart" or "boot-shaped heart"[1]) is a radiological sign seen most commonly in patients with tetralogy of Fallot,[2] 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.
