We report a case of hypertrabeculated left ventricular myocardium associated with congenital hypothyroidism in a preterm infant. The myocardical anomalies and long QT interval, absent at birth, appeared simultaneously to abnormal thyroid hormones and progressively improved until complete recovery during Levo-Thyroxine treatment. We speculate that thyroid dysfunction could be the potential cause of transient hypertrabecular aspect of the left ventricle.
