Introduction
Thyroid storm is a rare condition that involves severe clinical
manifestations of hyperthyroidism. It is life-threatening and requires
urgent treatment. In particular, thyroid storm after open heart surgery
is extremely rare, and there have been very few cases reported in the
literature. Herein, we report a case of thyroid storm that developed
after mitral valve repair surgery, which was very difficult to manage
because we were initially unable to diagnose it.
