【摘要】：目的探讨瓣膜置换术在巨大左心室患者临床治疗中的应用价值及其对心功能的影响。方法选取2003年8月-2013年10月该院收治的37例患者。所有患者行瓣膜置换术进行治疗。分别对患者治疗前后不同时间超声心动图指标、心功能(NYHA)分级情况进行比较,并统计患者并发症及死亡情况。结果与治疗前相比,患者治疗后1个月左心室舒张末期内径(LVEDD)和左心室收缩末内径(LVESD)下降,治疗后6个月LVEDD、LVESD及每博指数(SVI)下降,治疗后1年LVEDD、LVESD及SVI下降,左心室射血分数(LVEF)和左心室短轴缩短率(LVFS)提高。与治疗前相比,患者治疗后6个月和1年心功能Ⅰ、Ⅱ级比率提高,Ⅲ、Ⅳ级比率下降。患者术后早期死亡2例,死亡率为5.41%(2/37)。室性心律失常15例,低心排出量综合征14例,肺部并发症6例。结论瓣膜置换术能够有效改善巨大左心室患者心功能,且近期术后并发症和死亡率较低,其远期疗效则需做进一步的临床随访研究。
[Abstract]:Objective to evaluate the clinical value of valve replacement in the treatment of giant left ventricle and its effect on cardiac function. Methods 37 patients from Aug. 2003 to Oct. 2013 in our hospital were selected. All patients were treated with valve replacement. The echocardiographic parameters and cardiac function (NYHA) grading were compared before and after treatment, and the complications and death of the patients were counted. Results 1 month after treatment, left ventricular end diastolic diameter (LVEDD) and left ventricular end systolic diameter (LVESD) were decreased, LVEDD,LVESD and (SVI) were decreased at 6 months after treatment, and LVEDD,LVESD and SVI were decreased one year after treatment. Left ventricular ejection fraction (LVEF) and left ventricular shortening rate (LVFS) were increased. Compared with pre-treatment, the rate of cardiac function 鈪，
