Abstract

OBJECTIVE: There are limited data comparing aortic dimensions and elastic properties between transthoracic echocardiography TTE and transesophageal echocardiography TEE . Therefore, we aimed to investigate aortic dimensions and indices of aortic elastic properties as well as their relation with left ventricular LV filling and diastolic parameters obtained from TTE and TEE. METHODS: Forty two patients were included in the study. Aortic dimensions and related elasticity parameters, LV filling and diastolic parameters, left atrial volume index LAVi , LV mass index were calculated from TTE and TEE recordings in all patients. The correlation analyses were performed for aortic elasticity indices and LV filling and diastolic parameters obtained from TTE and TEE. RESULTS: There were no significant differences in aortic dimensions and elasticity indexes obtained from TTE and TEE. The correlation analysis revealed that while age E/A, E/E` and LAVi were significantly correlated with aortic elasticity indexes obtained from both TTE and TEE, LV mass index was significantly correlated with only TEE aortic elasticity indices. CONCLUSION: When compared to TTE, aortic elastic properties obtained from TEE were more closely related with LV filling and diastolic parameters. In addition, the indexes of aortic function were comparable between TEE and TTE with good intra and interobserver variability

Aortik elastisite ve aortik elastisitenin sol ventrikül dolum ve diyastolik parametreleri ile ilişkisinin transtorasik ve transözofajiyal ekokardiyografi değerlendirilmesi

Abstract

AMAÇ: Aort boyutlar ve elastik özelliklerini transtorasik ekokardiyografi TTE ve transözofageal ekokardiyografi TEE ile karşılaştıran sınırlı veri vardır. Bu nedenle, TTE ve TEE elde edilen aort boyutlar ve aortik elastik indekslerinin karşılaştırmanın yanı sıra bunların sol ventrikül LV dolum ve diyastolik parametreleri ile ilişkisini araştırmayı amaçladıkYÖNTEMLER: Çalışmaya kırk iki hasta dahil edildi. Tüm hastaların TTE ve TEE kayıtlarından aort boyutları ve ilgili elastikiyet parametreleri, sol ventrikül dolum ve diyastolik parametreleri, sol atriyal volüm indeksi LAVİ , sol ventrikül kütle indeksi hesaplandı. TTE ve TEE elde edilen aort elastikiyeti indeksleri ve sol ventrikül dolum ve diyastolik parametreleri için korelasyon analizi yapıldı.BULGULAR: TTE ve TEE ile elde edilen aort boyutları ve elastikiyeti indeksleri arasında anlamlı bir fark yoktu. Korelasyon analizinde yaş, E / A, E / E`ve LAVİ hem TTE hem de TEE ile edilen aort elastikiyeti indeksleri ile anlamlı derecede ilişkili iken, sol ventrikül kitle indeksi sadece TEE ile elde edilen aort elastikiyeti indeksleri ile ilişkili saptandıSONUÇ: TTE ile karşılaştırıldığında, TEE elde edilen aortik elastik özellikleri sol ventrikül dolum ve diyastolik parametreleri ile daha yakından ilişkili bulunmuştur. Buna ek olarak, TEE ve TTE ile elde edilen aort fonksiyon indeksleri iyi gözlemci içi ve gözlemciler arası değişkenliği ile benzerdir.
