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.

Fetal Congenital Heart Disease Echocardiogram Screening Based on DGACNN: Adversarial One-Class Classification Combined with Video Transfer Learning

IEEE Transactions on Medical Imaging, 2020
Fetal congenital heart disease (FHD) is a common and serious congenital malformation in children. In Asia, FHD birth defect rates have reached as high as 9.3%.

Training-Free Condition Video Diffusion Models for single frame Spatial-Semantic Echocardiogram Synthesis

International Conference on Medical Image Computing and Computer-Assisted Intervention
Conditional video diffusion models (CDM) have shown promising results for video synthesis, potentially enabling the generation of realistic echocardiograms to address the problem of data scarcity.

[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.

Use and Abuse of the Echocardiogram

Pediatric Clinics of North America, 1984
Echocardiography is a valuable noninvasive technology that has profoundly influenced the standards of medical and surgical care of infants and children with cardiac disease. The correct and efficient utilization of this technology requires a knowledge of the structures that can be visualized on the echocardiogram, the limitations of the technique, and ...

Unnecessary Pre-Operative Cardiology Evaluation and Transthoracic Echocardiogram Delays Time to Surgery for Geriatric Hip Fractures.

Journal of Orthopaedics and Trauma, 2020
OBJECTIVE Delays to surgery for geriatric hip fracture patients are associated with increased morbidity and mortality. The American Heart Association (AHA) and American College of Cardiology (ACC) Clinical practice guidelines (CPG) were created to ...

The Use of Echocardiograms in Preparticipation Examinations

Current Sports Medicine Reports, 2017
Sudden cardiac death (SCD) is the leading cause of death during exercise in young athletes. Preparticipation physical examinations were developed to maintain the health and safety of athletes, including the prompt identification of those at risk for SCD. The use of medical history and physical examinations, electrocardiography, and echocardiography, or

The Effect of Respiratory Motion on the Echocardiogram

Chest, 1976
The effects of respiratory movements on the ultrasonic echoes of the cardiac structures were recorded and analyzed in 50 consecutive patients. Deep inspiration in cooperative patients resulted in a considerable increase of dense anterior echoes, with blotting out of any distal or posterior echoes in 12 of 44 patients (group A).

The echocardiogram in left atrial myxoma

The American Journal of Medicine, 1973
Abstract A case of left atrial myxoma is described in which the echocardiogram provided the clue to the diagnosis. The mechanisms involved in producing a positive result are discussed. The value of the echocardiogram appears to depend upon echoes from the tumor during diastole which can be detected immediately posterior to the anterior cusp of the ...

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.
