0 the use of ultrasound (= sound waves used to produce images of the inside of someone's body) to examine the structure of the heart and how well it is working:
In the era of high-precision cross-sectional echocardiography, it now seems redundant to continue using normal data obtained from formalin-fixed autopsy specimens.
Echocardiography can usually identify the obstructive lesion in sufficient detail before surgical repair.
In the subsequent five patients, a precise diagnosis was obtained by echocardiography.
Because of this, he was referred to a cardiologist, who found signs of pericardial effusion, which was confirmed by echocardiography.

Postoperative echocardiography showed a satisfactory intracardiac repair with no residual shunts and minimal regurgitation across the left atrioventricular valve.
On fetal echocardiography, there was cardiomegaly with normal atrioventricular and ventriculoarterial connections and the heart rate was within normal limits.
They found that the diameters of both arteries were comparable to data of normal children which had been obtained by echocardiography.
