Abstract
in English, Turkish

Tissue Doppler Imaging (TDI) and TDI-derived strain provide considerably accurate information in the non-invasive assessment of local myocardial functions. Given its high temporal and spatial resolution, TDI allows assessment of local myocardial functions in each phase of cardiac cycle. However, the most important limitation of this method is its angle dependence. New techniques to measure myocardial deformation, such as speckle tracking echocardiography, overcome the angle-dependence limitation of TDI-derived strain. Moreover, these techniques provide more unique information about myocardial fiber orientation. This review examines the architectural structure and function of the myocardium and includes technical revisions of this information that will provide a basis for STE.

Doku Doppler görüntüleme (TDI) ve TDI kaynaklı strain bölgesel miyokardial fonksiyonların non-invasiv değerlendirmesinde oldukça doğru bilgiler vermektedir. Yüksek temporal ve spatial çözünürlüğü nedeniyle, kardiyak siklusun her fazında bölgesel miyokardiyal fonksiyonların değerlendirmesine imkan tanır. Ancak, bu metodun en önemli kısıtlılığı açı bağımlı olmasıdır. Speckle tracking echocardiography gibi miyokardiyal deformasyonu ölçen yeni teknikler, TDI kaynaklı strainin açı bağımlılığı limitasyonunun üstesinden gelebilmektedir. Üstelik miyokardial fiber orientasyonunu ile ilgili daha değerli bilgiler vermektedir. Bu derleme miyokardiyal mimari ve fonksiyonları ve STE için temel oluşturacak bu bilgilerin teknik olarak gözden geçirilmesini içermektedir.
