Abstract

Systolic cusp separation of normal aortic valves has been shown by echocardiography and by angiography to be related to left ventricular stroke volume. In this study, stroke volume was compared with echocardiographic area between the aortic cusps in systole (aortic ejection area). An excellent correlation was observed (r = 0.93) over a wide range of stroke volumes, even in the presence of mitral regurgitation. Stroke volume appears to correlate more closely with aortic ejection area than with angiographic or echocardiographic measurements of peak systolic cusp separation.

Noninvasive monitoring of stroke volume by pulsed Doppler echocardiog- raphy is an important recent advance in neonatal care. Using this technique, we assessed stroke volume in 112 healthy neonates (birth weight 780-5350 g, menstrual age 27-42 weeks). Stroke volume increased with advancing birth wei
