Abstract

Objective The aim of the present study was to review left ventricular (LV) deformation in idiopathic-dilated cardiomyopathy (DCM). Materials and methods The following data sources were searched: medical text books, medical journals, and medical websites that have updated researches with keywords 'left ventricle speckle tracking' in the title of the article. Systematic reviews that addressed LV speckle tracking and studies that addressed idiopathic-DCM were selected for the presents study. A special search was conducted at midline with the keywords 'left ventricle speckle tracking' in the title of the paper; extraction was performed, including the assessment of the quality and the validity of the papers that fulfilled the prior criteria that described the review. Each study was reviewed independently; the data obtained were rebuilt in a new language according to the need of the researcher and arranged into topics through the article. Results Speckle tracking echocardiography is an ideal tool for the assessment of the LV because of its regional and global functional characterization, angle independence, and high temporal resolution. The dimensions and function of the LV have been proven to be important indicators of LV impairment, primarily in patients with LV pressure and/or volume overload. This includes mainly patients with cardiomyopathy, heart failure, congenital heart disease, pulmonary hypertension, coronary artery disease, or arrhythmia. Conclusion LV speckle tracking would be an interesting diagnostic and prognostic entity to study DCM.
