1、中国超声医学杂志2017年4月第33卷第4期ChineseJUltrasoundMedVol.33No.4April2017—313—经食管实时三维超声研究不同反流程度二尖瓣脱垂患者瓣环动态变化崔翼靖陈昕张慧慧周文艳杨军摘要目的应用经食管实时三维超声心动图(RT-3DTEE)分析二尖瓣脱垂(MVP)患者不同程度反流瓣环立体结构在全心动周期的变化规律。方法57例行RT-3DTEE检查的患者,对照组33例,MVP患者24例,其中14例为二尖瓣中-重度反流组,10例为二尖瓣轻度反流组。应用QLab7.0软件分别于舒张早、中、晚期和收缩早、中、晚期测量二尖瓣瓣环。结果
2、与对照组相比,轻度MR组DAP于收缩中晚期、舒张早期、舒张晚期增大(P<0.05);中-重度MR组于全心动周期瓣环C3D、A2D、DAP、DAlPm均明显增大(P<0.05)。与轻度MR组相比,中-重度MR组DAP于全心动周期均明显增大,A2D、C3D、DAlPm于收缩晚期、舒张中期增大(P<0.05),而H、H/DAlPm差异均无统计学意义(P>0.05)。结论不同程度MR瓣环结构变化不同,瓣环前后径扩大比前外后内径出现较早。关键词超声心动图三维经食管二尖瓣脱垂二尖瓣瓣环QuantitativeAssessmentofMitralAnnulusDynamic
