Type one muscular dystrophy (DM1) is the most common inherited muscular dystrophy in the adult population. Typically, DM1 presents as myotonia, muscle weakness, cataracts, and cardiac abnormalities, mainly in the conduction system. Although left ventricular dysfunction is not the most common manifestation of DM1, it can be seen with disease progression. The presentation of DM1 as a de novo heart failure is unusual, making its diagnosis a clinical challenge.
