The abnormality mitral stenosis was in myocardium, not in the valve. 二尖瓣狭窄的病变是在心肌而不是在瓣膜。
Aim: To measure left ventricular long axis function in the patients with rheumatic mitral stenosis( MS). 目的:检测风湿性心脏病二尖瓣狭窄(S)者左心室纵轴功能。
Methods:MVA were measured in 21 patients with pure mitral stenosis by 6 methods and the other 5 were compared with AFCE. 方法：在21例单纯二尖瓣狭窄患者，利用上述6种方法测量MVA，以AFCE测值为标准进行对比研究。
Conversely, a diminished or absent S1 in mitral stenosis suggests a rigidly calcified valve that cannot "snap" shut. 相反，二尖瓣狭窄时S1减弱或消失，表明瓣叶严重钙化，无法关闭。
Conclusion：As a treatment for appropriate patients with mitral stenosis, PBMV has good long-term results. 结论：PBMV术后可保持较好的远期疗效，不失为治疗风湿性二尖瓣狭窄的有效方法。
Objective To study the relationship between the degree of mitral stenosis (MS) and atrial filling fraction (AFF). 目的研究二尖瓣狭窄程度与左房充盈分数的关系。
Analysis of the effects by percutaneous mitral balloon valvutoplasty in rheumatic mitral stenosis. 本文分析经皮球囊二尖瓣成形术治疗风湿性二尖瓣狭窄的疗效。
Conclusion PBMV as a treatment for appropriate patients with mitral stenosis has good long-term results. 术前超声心动图计分、心功能、有无心房颤动和左房压为长期疗效的独立预测因素。
Objective: To analyze the characteristics and occurrence of silent mitral stenosis(SMS) in rheumatic heart disease. 目的：分析风湿性心脏病哑型二尖瓣狭窄的发生及特点。
In many cardiac disorders, dyspnea due to a fixed cardiac output and that due to pulmonary congestion occur simultaneously( eg, in mitral stenosis). 在许多心脏疾病中，由固定心排血量引起的呼吸困难常与肺充血引起的呼吸困难同时发生(如二尖瓣狭窄)。
The preliminary results of prosthetic valve replacement for mitral stenosis using artificial chordae with preservation of the subvalvular apparatus. 瓣膜替换治疗二尖瓣狭窄用人工腱索保留瓣下结构的初步观察。
In many cardiac disorders, dyspnea due to a fixed cardiac output and that due to pulmonary congestion occur simultaneously (eg, in mitral stenosis). 在许多心脏疾病中，由固定心排血量引起的呼吸困难常与肺充血引起的呼吸困难同时发生(如二尖瓣狭窄)。
Objective To evaluate the efficacy and safety of percutaneous balloon mitral valvuloplasty(PBMV) in the geriatric patients with mitral stenosis. 目的探讨老年二尖瓣狭窄患者接受经皮球囊二尖瓣成形术(PBMV)的疗效和安全性。
Method: 4 cases of rheumatic mitral stenosis were treated by PBMV with single balloon catheter.Result: All of the 4 cases were successfully operated. 方法:采用国产单球囊导管对4例风湿性心脏病二尖瓣狭窄患者进行PBMV。
Combination of simple mitral stenosis and mitral incompetence can breakdown the risk for formation of atria sinistrum mural thrombosis. 单纯二尖瓣狭窄时二尖瓣关闭不全的存在使左房血栓形成的风险下降。
Objective To evaluate the value of acoustic quantification technique in assessment of right ventricular(RV) function in patients with mitral stenosis. 结论声学定量技术能有效地观察测量二尖瓣狭窄治疗前后右室功能的变化,为临床提供判断疗效的依据。
We compared changes of hemodymamics and car-diac function before and after percutaneous balloon mi-tral valvuloplasty(PBMV)in 75 patients with rheumatic mitral stenosis. 本文观察了75例风湿性二尖瓣狭窄(MS)患者经皮球囊导管二尖瓣成形术(PBMV)治疗前、后的血流动力学和心功能的变化.
Objective To observe safty and effect of percutaneous balloon mitral valvuloplasty(PBMV) on the patients with rheumatic mitral stenosis complicated with left atrial thrombus. 目的探讨经皮球囊成形术(PBMV)治疗合并左房血栓的风湿性二尖瓣狭窄的可行性、安全性和临床效果。
S1 may be loud and "snapping" in quality in mitral stenosis, indicating both that the valve is pliable and that it remains wide open at the beginning of isovolumic contraction. 二尖瓣狭窄时S1响亮、呈喀嚓声，既表明瓣膜柔软，也表明瓣膜在等容量收缩开始时仍张开着。
Objective:To observe whether percutaneous transluminal ballonmitral valvuloplasty (PTBMV) can improve the pulmonary function of patients with single mitral stenosis (MS). 目的：观察单纯二尖瓣狭窄(MS)患者接受经皮腔内球囊二尖瓣成形术(PTBMV)治疗前后的肺功能指标的变化。
