Abstract

Several echocardiographic methods have been proposed to assist patient selection for cardiac resynchronization therapy. Color-coded tissue Doppler is one of the most promising methods to quantify mechanical dyssynchrony. However, tissue Doppler data are affected by Doppler angle of incidence and tethering or translational motion. Furthermore tissue Doppler based modalities are good for longitudinal motion analysis but limited in other directions of wall motion such as radial, circumferential, and rotational. Speckle tracking is a more recent technique that allows accurate calculation of regional radial and circumferential strain as well as regional rotation for dyssynchrony analysis. Although no ideal echocardiographic method exists that integrates regional dyssynchrony data in all contraction directions as yet, technical refinements and advances in understanding of pathophysiology will help to improve the study of mechanical dyssynchrony.

Özet

Kardiyak resenkronizasyon tedavisine aday hastaların seçimine yardımcı olabilecek çeşitli ekokardiyografik yöntemler önerilmiştir. Mekanik senkronizasyon bozukluğunu değerlendirmede en ümit vaad eden tekniklerden bir tanesi renkli doku Doppler ekokardiyografidir. Ancak doku Doppler verileri açı bağımlıdır ve itme çekilme ile translasyon hareketinden etkilenir. Bunun da ötesinde doku Doppler temelli yöntemler uzun eksen hareketinin analizine uygun iken radiyal, sirkumferansiyel ve rotasyonel hareketlerin incelenmesinde kısıtlılık gösterir. Benek takibi daha yeni bir teknik olup bölgesel radiyal ve sirkumferansiyel strain ve bölgesel rotasyon analizi için elverişlidir. Halen tüm kasılma yönlerindeki senkronizasyon bozukluğunu bir arada değerlendirebilen tek bir ideal ekokardiyografi yöntemi olmamasına rağmen, teknik gelişmeler ve patofizyolojik özelliklerin daha iyi kavranması ile mekanik senkronizasyon bozukluğu daha iyi ve doğru değerlendirilebilecektir.
