To exploit this capability, both the sonographer and the cardiologist interpreting the ultrasound images require extensive training. Performing a proper ultrasound examination requires that the sonographer be knowledgeable on the correct placement

How to Perform an Acoustic Quantification Study: Technical Factors Influencing Study Quality and Pibeat-to-beat values for left ventricular (LV) cavity area and volume. These measurements can then be used to calculate load-dependent parameters of systolic performance such as ejection fraction and stroke volume in real-time. In addition, it is possible to generate load-independent parameters of sy

Evaluation of Left Ventricular Diastolic Function Using Acoustic Quantification, in 1984. In his study of 188 patients with heart failure, 36% of the patients had normal or near normal left ventricular (LV) systolic function, with ejection fractions of 0.45 or greater. Echocardiographic findings in these patients demonstrated an abnormally low left atrial emptying index which s

Indirect atrial assessment of LA function during cardiac catheterization includes measurements of pulmonary capillary wedge pressure or left ventricular (LV) end diastolic pressure (LVEDP) but rarely involves direct measurement

Conventional clinical assessment of regional wall motion abnormalities is based on visual interpretation of the magnitude of systolic endocardial excursion and wall thickening.
