Report of the American Society of Echocardiography Committee on Nomenclature and Standards in Two-dimensional Echocardiography.
The Committee recommends that when the transducer is placed in the suprasternal notch that it be referred to as in the suprasternal location. When the transducer is located near the midline of the… Expand
Echocardiography of the aortic root.
The echo pattern of the aortic root is elicited by locating the typical echo of the mitral valve and then angulating the transducer medially and sometimes cephalically. The characteristic echo… Expand
Ultrasound cardiography: contrast studies in anatomy and function.
Ultrasound cardiography has become established as a valuable clinical tool in the detection of pericardial effusion (1) and the study of mitral valve disease (2, 3). The tricuspid valve can also be… Expand
Ultrasound Localization of Left Ventricular Outflow Obstruction in Hypertrophic Obstructive Cardiomyopathy
Simultaneous recordings of reflected ultrasound from the anterior mitral leaflet and left ventricular outflow, the ECG, the phonocardiogram, and a recording of the carotid artery pulse were obtained… Expand
Sono-Elasticity: Medical Elasticity Images Derived from Ultrasound Signals in Mechanically Vibrated Targets
Cancers of the prostate have traditionally been detected by digital palpation which identifies increased stiffness (modulus of elasticity, hardness) of the abnormal tissue. Gray-scale ultrasound is… Expand
Ultrasound localization of left ventricular outflow obstruction in hypertrophic obstructive cardiomyopathy
Influence of the timing of atrial systole on mitral valve closure and on the first heart sound in man.
Abstract Simultaneous recordings of electrocardiogram, phonocardiogram, indirect carotid pulse and pulsed ultrasound cardiogram of the anterior mitral leaflet were obtained in patients with heart… Expand
The reliability of echocardiography in the diagnosis of infective endocarditis.
The echocardiograms of 17 patients with proved infective endocarditis were surveyed to assess the reliability of echocardiography in this disease. Vegetations were present on 20 valves (11 aortic, 7… Expand
Representations of rapidly oscillating structures on the Doppler display.
In cardiovascular applications of Doppler ultrasound, oscillating structures are at times within the sample volume of the transducer. When the period of oscillation is shorter than the time window of… Expand
