심부전증에서 관정맥동의 심초음파적인 측정

다국어 초록 (Multilingual Abstract)

The coronary sinus(CS) is a small tubular structure just below the tricuspid valve. The dilatation of the coronary sinus as well as the inferior vena cava and the hepatic vein may provide echocardiographic signs of systemic congestion. To observe the difference in the size of CS in various heart diseases especially in patients with congestive heart failure, we m e a d the CS by using a two-dimensional echocardiogram in right ventricular inflow view(5-10 mm below the Thebesian valve at end-systolic phase) of 58 patients (M:F=20:38) with congestive heart failure(group 11, 63 patients(M:F=27:36) of various heart disease without congestive symptom(group 2) and 94 healthy volunteers(control group, M:F=52:42).
In the normal control group the size of CS is 6.2±1.2 mm, and shows no significant difference between gender, and no significant correlation between size of CS and age. The size of CS in group 1 and 2 are 9.0±2.3 mm and 6.4±1.3mm. respectively. There are significant differences between group 1 and the normal control group(p<0.00l), and between group 1 and group 2 (p<0.00l), but no significant change between group 2 and the normal control group. In group 1, the size of CS shows a significant correlation to the duration of heart failure(r = 0.32, p<0.016), but there shows no significant correlation to body surface area, left ventricle dimension, and TR peak velocity. If the presence of heart failure diagnosed according to the size of CS , the predictive value is high at the size of CS exceeds 8.0mm. Accuracy is 84%. In heart failure, the size of IVC are 16.6±5.4mm, the variation rate of IVC during respiratory cycle are 0.40±0.13, and the variation rate of CS during cardiac cycle are 0.31±0.20. There is no significant correlation between the sue of CS and the size of IVC, hut there is a significant inverse correlation between the size of IVC and the variation rate of IVC(r=-0.434, p<0.05). There is a significant inverse correlation between the size of IVC and the variation rate of CS(r=-0.490, p<0.05). There is a significant correlation between the variation rate of CS and the variation rate of IVC(r=0.411, p<0.05). The measurement of the size of CS and variation rate of CS provide valuable information concerning presence and duration of congestive heart failure.
