A Rare Cause of Cardiomyopathy: A Case of Selenium Deficiency Causing Severe Cardiomyopathy that Improved on...

Selenium-associated cardiomyopathy is a rare but potentially fatal condition that has previously been described in the literature. Once identified, the condition may be reversible via supplementation. Gastrointestinal operations, especially bariatric and bowel resection, are increasingly associated with multiple deficiencies, including a deficiency of the micronutrient selenium (Se). This case report presents a patient with Se-deficient cardiomyopathy whose condition improved due to Se replacement.
