Abstract (2. Language): 
It is well known that; examination of heart valves by transesophageal echocardiography (TEE) is superior to transthorasic echocardiography (TTE). In this study we aimed to evaluate differences between TEE and TTE for measurement of aortic valve area. 3 women (mean age: 55±8) and 12 men (mean age: 58+7) total 15 patients with calcific aort stenosis were included in the study. Aortic valve area measured by TTE. Alter premedication, left ventricular outflow tractus (L VOT) was measured by TEE using continuity equation aort valve area measured again.Mean gradient was calculated 32 mmHg by TTE. L VOT was measured 1.8 cm by TTE while 2.2 cm by TEE (p<0.05). Referency to the LVOTmeasurments aort valve area was measured 1 cm2 by TTE and 1.4 cm2 by TEE. Because of examination of L VOT is more accurate by TEE, we belive that as a noninvasive method using TEE is more reliable for measurement of aortic valve area.

Abstract (Original Language): 
Kalp kapaklarının değerlendirilmesinde transözefajial ekokardiyografinin (TEE) transtorasik ekokardiyografiye (TTE) üstünlüğü bilinmektedir. Bu çalışmada aort kapak alanı hesaplanmasında duyarlılık açısından TEE ile TTE arasında fark olup olmadığı tespit edilmek istendi. Çalışmaya TTE ile kalsifik aort darlığı saptanan 3 kadın (yaş ort: 55±8 yıl), 12 erkek (yaş ort:58±7 yıl) olmak üzere toplam 15 hasta alındı. Hastaların aort kapak alanları TTE ile hesaplandı. Daha sonra premedikasyonun ardından TEE ile sol ventrikül çıkış traktüsü ölçüldü. Ardından süreklilik denklemi kullanılarak aort kapak alanı tekrardan değerlendirildi. TTE'de ortalama gradient 32 mmHg ölçüldü. TTE ile sol ventrikül çıkış traktüsü (LVOT) 1.8 cm ölçülürken, TEE'de 2.2 cm olarak değerlendirildi (p<0.05). Ölçülen LVOT değerlerine göre hesaplanan aort kapak alanı TTE'de 1 cm2 bulunurken TEE'de 1.4 cm2 olarak bulundu (p<0.01). TEE ile LVOT ölçümü gerçek değere daha yakın olarak tespit edilebildiğinden dolayı aort kapak alanının noninvaziv değerlendirilmesinde daha doğru bir yaklaşım olacağı kanısındayız.
