- mitral regurgitant flow 二尖瓣回流
- Purpose:The aim of the study was to quantitate analogue mitral regurgitant (MR)jet size with three dimensional(3D)reconstruction in vitro pulsatile flow model. 目的：采用三维（3D）超声重建技术定量评价模拟二尖瓣返流（MR）的大小。
- Methods By directly integrating the mitral regurgitant jet in space and in time during the systole, 19 patients with eccentric MR were examined by the modified ACOM, and the severity of the 19 patients using RV as evaluation parameter was graded. 方法对19例患偏心性反流患者采用ACOM改进法,于收缩相对经二尖瓣反流瓣口的血流速度直接进行时间和空间双重积分,得到二尖瓣反流量,并将反流量作为评价参数,对患者的反流严重程度进行划分。
- Mitral regurgitation is one of the most serious heart diseases. 二尖瓣返流是心脏疾病最主要的发病之一。
- Objective To assess the clinical signi ficance on the degree of mitral regurgitation by the use of pulsed doppler echocardiogrphy to examine the pulmonary veins flow. 目的探讨脉冲多普勒肺静脉血流评价二尖瓣返流的程度。
- Clinical left ventricular enlargement with secondary mitral regurgitation? 临床上有否左心室扩大伴二尖瓣返流?
- No operative deaths. no residual mitral regurgitation and stenosis occured. 术后恢复平稳，没有手术死亡，无二尖瓣关闭不全和二尖瓣狭窄发生。
- TDI for Assessing Left Ventricular Function in Patients with Significant Mitral Regurgitation. 严重二尖瓣关闭不全病人左室功能的组织多普勒评价。
- Moderate mitral regurgitation was more common in eccentric left ventricular hypertrophy group. 离心性肥厚组中度二尖瓣反流者较多。
- The valve regurgitate flow usually occur in multiple mainveins in DDVI, and in femoral veins in DVI. DDVI组发生返流瓣膜组合是以多条大静脉同时出现为主，而DVI组则以单根为主。
- Objective To analyze the cause of mitral regurgitation(MR) after percutaneous balloon valvuloplasty (PBMV). 目的分析经皮二尖瓣球囊成形术(PBMV)并发二尖瓣关闭不全(MR)的原因。
- The valve regurgitate flow usually occur in multiple mainveins in DDVI,and in femoral veins in DVI. DDVI组发生返流瓣膜组合是以多条大静脉同时出现为主 ,而DVI组则以单根为主。
- Instead of a decreased right ventricle, this could also correspond to an increased left ventricle. This would probably be due to late aortic stenosis or mitral regurgitation. 假如不是右心室缩小，那可能就是左心室增大，这可能是由于主动脉瓣狭窄或二尖瓣返流导致。
- ObjectiveTo summarize the experience in surgical technique and clinical results of treating ischemic mitral regurgitation (IMR). 目的探讨缺血性二尖瓣关闭不全(IMR)手术治疗的方案。
- Objective: To explore the value of the vena contracta(VC) method in quantitative diagnosis of eccentric mitral regurgitation(EMR). 目的:探讨射流紧缩面法定量评价二尖瓣偏心反流的价值。
- Objective:To evaluate vary cases morphology character of mitral regurgitation caused by different causes by Color Doppler Flowing Imaging(CDFI). 目的:采用彩色多普勒血流显像技术,评价由不同病因引起的二尖瓣返流形态学特征。
- Here we describe one 3 month-old female infant with congestive heart failure and one 13 year-old girl with mitral regurgitation and hemoptysis. 我们陈述两个案例，分别是呈现心衰竭的三个月女婴和二尖办回流并有咳血的十三岁女孩。
- Echocardiographic study revealed marked mitral regurgitation with a large vegetation on the atrial side of the anterior leaflet of the mitral valve. 超声心动图显示明显的二尖瓣返流，伴有二尖瓣前叶心房侧大的赘生物。
- Results:The differences of mitral regurgitation in color Doppler flowing morphology,color and position caused by vary heart disease were found. 结果:发现不同心脏疾病引起的二尖瓣返流,彩色多普勒血流形态、色彩、所处位置及收缩时长存在差异。
- Objective To investigate and validate a modified automatic cardiac output measurement (ACOM) method to quantify the eccentric mitral regurgitation (MR). 目的研究并证实自动心脏输出量测量法(ACOM)改进法定量评价二尖瓣偏心性反流。
