53±10(17～71)岁的100(男87,女13)例患者作左右心室造影,左前斜位45°和右前斜位45°的双平面X线片同时摄取。其中冠心病81例,扩张型心肌病6例,肥厚型心肌病2例,11例造影未见异常。A组27例示有三尖瓣脱垂,B组73例未见三尖瓣脱垂。A、B两组的年龄、性别、肺动脉压(收缩压、舒张压和平均压)和三尖瓣关闭不全发生率(18/27对 39/73,NS)均无显著差异。A、B两组的右室舒张末容量指数无显著差异(93±34对98±23ml/m~2,NS),A组右室收缩末容量指数小于B型(39±16对47±17ml/m~2,P<0.05),A组右室射血分数大于B组(58±10％对53±10％,P<0.05)。本
A total of 100 (male 87, female 13) patients aged 53 ± 10 (17-71) years were enrolled in a bi-planar radiograph with simultaneous left ventricular angiography, left anterior oblique 45 °, and right anterior oblique 45 °. Of which 81 cases of coronary heart disease, dilated cardiomyopathy in 6 cases, hypertrophic cardiomyopathy in 2 cases, 11 cases no abnormalities. A group of 27 cases showed tricuspid valve prolapse, B group 73 cases no tricuspid valve prolapse. Age, sex, pulmonary arterial pressure (systolic pressure, diastolic pressure and mean pressure) and tricuspid regurgitation incidence (18/27 vs 39/73, NS) in groups A and B were not significantly different. The right ventricular end-diastolic volume index in groups A and B had no significant difference (93 ± 34 vs 98 ± 23 ml / m ~ 2, NS), but the index of right ventricular end systolic volume in group A was less than that of type B (39 ± 16 vs 47 ± 17ml P <0.05). The right ventricular ejection fraction in group A was greater than that in group B (58 ± 10% vs 53 ± 10%, P <0.05). this
