Abstract

Objective: Integrated backscatter (IBS) is an objective method to measure spontaneous echo contrast (SEC) quantitatively. The purpose of this study was to investigate the relationship between the quantitative values of left atrial SEC measured by using IBS with its qualitative gradation as well as the left atrial appendix (LAA) functions and LAA tissue Doppler characteristics (TD). Methods: Thirty-two patients (23 female, 9 male) with various diseases undergoing transesophageal echocardiography (TEE) were included. Mean age was 52+13 years. Left atrial SEC was graded as no SEC (n=12), mild (n=12) or severe SEC (n=8) in patients underwent TEE. LAA peak emptying and LAA apical and basal TD velocities were measured. LAA ejection fraction was assessed by standard means. Results: Between no SEC and mild SEC groups, left atrium IBS and LAA apical TD values were found statistically significant. But there were no differences between two groups regarding LAA emptying velocities, LAA ejection fraction values and LAA basal TD values. All of these parameters were found statistically different between severe and mild SEC groups. The left atrial IBS values were found to be correlated positively with the qualitative SEC grade. The left atrial IBS values correlated negatively with LAA emptying, apical TD velocities and LAA ejection fraction values. Conclusion: Integrated backscatter provides an objective quantitative measure of SEC that correlates well with LAA apical TD velocities and the other parameters of LAA.

Özet

Amaç: İntegrated backscatter (IBS) spontan ekokontrast'ı (SEK) kantitatif olarak belirleyen bir yöntem olarak kullanılmaktadır. Çalışmanın amacı kantitatif olarak belirlenen sol atriyum SEK değerlerinin, kantitatif olarak belirlenen SEK dereceleri ile sol atriyal appendiks (SAA) fonksiyonları ve SAA doku Doppler'i (DD) ile ilişkisini araştırmaktır. Yöntem: Çeşitli sebeplerle transözofajiyal ekokardiyografi (TÖE) uygulanan 32 olgu (23 kadın, 9 erkek) çalış-maya alındı. Ortalama yaş 52 ± 13 yıl idi. TÖE yapılan olgularda sol atriyum SEK'İ kalitatif olarak SEK yok (12 olgu), SEK hafif (12 olgu) ve SEK yoğun (8 olgu) olarak sınıflandırıldı. SAA'dan, SAA ileri akım hızı, SAA api-kal ve bazal DD akım hızları alındı. SAA ejeksiyon fraksiyonu hesaplandı. Bulgular: SEK yok ve SEK hafif grup arasında sol atriyum IBS, SAA apikal DD değerleri istatistiksel olarak anlamlı bulundu. Ancak SAA ileri akım hızı, SAA ejeksiyon fraksiyonu ve SAA bazal DD değerleri anlamlı bulun-madı. SEK hafif ve SEK yoğun gruplar arasında bütün bu parametreler istatistiksel olarak anlamlıydı. Sol atriyum İBS değerlen ile kalitatif SEK dereceleri arasında pozitif korelasyon saptandı. Sol atriyum İBS değerleriyle SAA ileri akım hızı, SAA ejeksiyon fraksiyonu, SAA apikal DD arasında negatif korelasyon bulundu. Sonuç: SEK'in kantitatif İBS değerleri, SAA apikal DD ve SAA diğer parametreleri ile uyumludur.
