Normal coronary arteries and isolated, regional, left ventricular dysfunction in myotonic dystrophy: a case report

Development of cardiomyopathy in myotonic dystrophy is rare. Regional ventricular abnormality in the presence of normal coronary vessels has not been reported in this condition. We describe a case of isolated, regional, left ventricular dysfunction with corresponding defects on nuclear perfusion imaging in a patient with classical myotonic dystrophy and normal coronary arteries.
