Abstract

Dilated cardiomyopathy is a rare complication of hypothyroidism. Studies with standard echocardiography have established that compromised left ventricular systolic dysfunction associated with hypothyroidism is reversible after hormone replacement therapy. Speckle tracking strain imaging has been used to evaluate subtle myocardial dysfunction and regional wall-motion abnormalities in the context of normal ejection fraction. We report a case of a 15-year-old female of primary hypothyroidism and dilated cardiomyopathy in which residual subclinical left ventricular systolic dysfunction was detected by two-dimensional speckle-tracking echocardiography after recovery of ejection fraction.
