Reverberations in echocardiograms

Journal of Clinical Ultrasound, 1977
AbstractDifferent types of reverberations which may cause confusing artifacts in echocardiograms are described. Reverberations between the targets may result in identifiable complex echo patterns. An echocardiogram with reverberating echoes is presented. Several experimental studies were done to explain the reverberating echoies.

[The normal echocardiogram].

Soins; la revue de reference infirmiere, 1981
The echos of the mitral valve are a useful landmark for the rest of the echocardiographic examination. They usually are the easiest to record and, from a historical point of view, they were among the first to be described48.

Echocardiogram in calcified mitral anulus

The American Journal of Cardiology, 1975
Abstract Calcification of the anulus fibrosus of the mitral valve presents a characteristic pattern on the echocardiogram. This pattern may be mistaken for that of a posteriorly situated pericardial effusion. Two illustrative cases are presented.

Esophageal Perforation After Transesophageal Echocardiogram

Echocardiography, 1999
Esophageal rupture after transesophageal echocardiogram (TEE) is a rare but life‐threatening complication. Risk factors for perforation include spasm or hypertrophy of the cricopharyngeal sphincter, cervical arthritis, forward and left lateral bending of the distal esophagus, and esophageal disease such as inflammation or neoplasm.

Fourier analysis of the echocardiogram

Physics in Medicine & Biology, 1978
Fourier analysis has been applied to the analysis of echocardiograms, with the result that anterior mitral leaflet waveforms have been classified in a manner which is unambiguous and which lends itself easily to present-day automated technology.

Neonatal echocardiograms of macrosomic neonates

Journal of Perinatal Medicine, 2000
To compare echocardiograms of macrosomic and healthy full term neonates whose weight was appropriate for gestational age (AGA).Echocardiography was performed on 9 healthy full term AGA neonates and 15 macrosomic neonates. A data base was generated from valid echocardiographic measurements on each infant.Macrosomic infants were heavier than control ...

Out-of-Hospital Transesophageal Echocardiogram for Cardiac Arrest Resuscitation: The Initial Case

Prehospital Emergency Care, 2019
Objective: The use of transesophageal echocardiogram (TEE) during cardiac arrest in the emergency department (ED) is a newer concept. TEE provides dynamic evaluation of chest compressions and rhythm analysis.

Systematic analysis of contrast echocardiograms

The American Journal of Cardiology, 1983
Contrast echocardiography was first described in 1968. Since then, many reports have described clinical and experimental uses for the technique. Contrast echocardiography is performed at least occasionally in most echocardiography laboratories, but most physicians use this technique merely to determine the presence of a shunt or, more rarely, for ...
