OBJECTIVES Knowledge of aortic valve function has been obtained from experimental studies. The aim of the present study was to investigate characteristics of aortic valve motion in humans. METHODS(More)
BACKGROUND Common 3D systems have only limited spatial and temporal resolution (frame rate of 25 Hz). Thin structures such as cardiac valves are not imaged exactly; rapid movement patterns cannot be(More)
Determination of cardiac output is a potentially important clinical application of three-dimensional (3-D) echocardiography since it could replace invasive measurements with the Swan-Ganz-catheter.(More)
Quantification of the left ventricular (LV) volume by three-dimensional echocardiography is accurate but time-consuming. To shorten the time required, we sought to determine the minimum number of(More)
