Value of Pulsed Doppler Echocardiography in the Diagnosis of Aortic Regurgitation

ABSTRACT

In order to assess the sensitively and specificity of the pulsed Doppler echocardiography in the aortic regurgitation, 44 patients with valvular heart diseases were examined by pulsed Doppler echocardiography. Every patient was examined in sequence of clinical examination including the physical, M-mode & 2D echocardiographic examination, Doppler technique and then angiocardiography. The obtained results were; 1) Pulsed Doppler echocardiography was very useful in the diagnosis of the aortic regugitation(sensitivity100%, specificity90%). 2) Pulsed Doppler echocardiography was especially useful in the detection of the aortic regurgitation in patients who were not detected by physical and conventional echocardiographic examination.
