Abstract:
An statistical analysis of aorta-septal angle(AS angle) between anterior wall of aorta and ventricular septum was taken,AS angle was measured fromthe right ventricle with long-axis, two-dimensional echocardiongram of the left ventricle in 227 consecutive cases of patients with cardiovascular diseases and 80 healthy adults since 1985. It was found that AS angle for normal adults at the end of systoie(ES) and the end of diastole(ED) being 118.50?? 7.70? and 110.60??8.23?; the difference between ES and ED was 7.89??4.51?. In patients with overburdening of left ventricular volume and resistance of coronary artery disease, car-diomycpathy and hypertension , AS angles were amaller,and in patients with overburdening of right ventricular pressure of rheumatic mitral stenosis, AS angles were larger than healthy adults. The difference between ES and ED was smaller than normal for all patients. It was also found that in patients with heartdisease AS angle tends to be smaller or larger before the appearance of abnormality of the left ventricular cavity. Our data suggested that AS angle variance might afford some clinical significance of diagnosis
