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: --
Spontaneous closure of muscular ventricular septal defect identified by echocardiography in neonates.
On echocardiography, the left ventricular cavity was hypoplastic with a small muscular ventricular septal defect.
A better understanding of the flow patterns seen in this noninvasive technique is essential in maximizing the role of echocardiography as a diagnostic tool.
The monitoring transoesophageal echocardiography probe is also clearly visible.
Echocardiography showed normal chamber and vessel relationships, a small patent arterial duct, and an atrial septal defect with bidirectional shunting across the oval fossa.
Echocardiography is the ideal investigation as information can be obtained about cardiac valves as well as ventricular function.
On echocardiography, both great arteries were seen to arise from a leftward and posteriorly located, finely trabeculated ventricle.
They found that the diameters of both arteries were comparable to data of normal children which had been obtained by echocardiography.
