ABSTRACT
Left ventricular systolic dysfunction (LVSD) is a common finding in patients with Duchenne (DMD) and Becker (BMD) muscular dystrophies. Novel echocardiographic techniques have been used for the detection of LVSD in several heart diseases. We aim to compare cardiac anatomic and functional data studied by three-dimensional (3DE) and two-dimensional (2DE) echocardiography and to analyze the myocardial strain for the detection of early LVSD in DMD and BMD patients. We performed a cross-sectional study of 46 DMD and 14 BMD patients. We measured left atrium volume and left ventricle volumes and ejection fraction using 3DE and 2DE techniques. Myocardial strain analysis was derived from global longitudinal strain (GLS) measurements. GLS was measured by 2DE with the speckle tracking technique. The correlation between 3DE and 2DE for the measurement of left atrium volume as well as left ventricle diastolic and systolic volumes was strong. 2DE presented larger left atrium and left ventricle volumes. Left ventricle ejection fraction was similar between the two techniques. Myocardial strain analysis was able to detect early LVSD in 50.0% of DMD patients and in 9.1% of BMD patients. In conclusion, two-dimensional echocardiography appears to be a good alternative for the anatomical and functional evaluation of the left heart chambers in DMD and BMD patients. Myocardial strain analysis detects early LVSD in a sizable portion of patients with dystrophinopathies.
