超声心动图和胸片连续观测左至大小和功能在决定慢性主动脉瓣反流的治疗方面常起关键作用.作者分析平均年龄49(24～77)岁的22(男19、女3)例中～重度慢性主动脉瓣反流而无临床症状的患者相隔3个月的二次M型超声心动图及胸片测值间变异.其中先天性二叶式主动脉瓣11例,风湿性心脏病4例,心内膜炎2例及原明未明者5例.本组无一例伴有主动脉瓣狭窄或其它瓣膜病变.检查前停用心血管活性药物.检查中均为窦性心律.首次检查后一年内病情稳定,治疗未变,超声心动图复查左室大小和功能无进行性改变.
Continuous echocardiography and chest radiograph observation of left to size and function often play a key role in determining the treatment of chronic aortic regurgitation. The authors analyzed 22 (19 males, 3 females) patients with an average age of 49 (24-77) years Moderate to severe chronic aortic regurgitation without clinical symptoms in patients separated by 3 months after the second M-mode echocardiography and chest X-ray variability among them, including congenital bile duct aortic valve in 11 cases, rheumatic heart 4 cases of endocarditis, 2 cases of endocarditis and 5 cases of untreated patients.No case of aortic valve stenosis or other valvular disease was found in this group.Animal cardiovascular activity was stopped before the test.All the patients had sinus rhythm. During the first year after the first check, the condition was stable and the treatment had not changed. Echocardiography was used to review the left ventricular size and function without any change.
