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:^{[citation needed]}

• 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.
