摘 要:目的探讨实时三维经食管超声心动图(RT3D-TEE)指导下全胸腔镜技术行二尖瓣成形术的意义及术后近中期效果评价。方法选取2016年1月至2018年12月在空军军医大学第一附属西京医院采用全胸腔镜技术行二尖瓣成形术治疗二尖瓣关闭不全的147例患者临床资料,其中男性97例(66.0%)、女性50例(34.0%),年龄10~68岁,平均年龄(45.8±14.5)岁,术前均行RT3D-TEE检查,观察二尖瓣病变部位、分析反流机制、测量二尖瓣结构各项指标,帮助手术医师选择成形环型号及手术方式。术后即刻行RT3D-TEE评价二尖瓣成形效果,随诊时记录经胸超声心动图结果。采用单因素方差分析比较术前和术后LA左右径、LV前后径、LVEF、EDV、ESV以及二尖瓣反流或狭窄情况等指标的变化,有统计学意义的组间进行LSD-t检验。结果全组无围手术期死亡患者,有2例术中成形失败转而选择二尖瓣置换术,二尖瓣成形即刻成功率为98.6%。中期随访超声心动图显示,二尖瓣无或微量反流114例(78.6%),少量反流19例(13.1%),少-中量反流10例(6.9%),中量反流2例(1.4%)。术后出现二尖瓣前叶收缩期前向运动(SAM征)0例;二尖瓣前向血流速度加快8例。与术前比较,术后1个月、3个月、12个月LA左右径、LV前后径、EDV、ESV较术前均缩小[分别为LA左右径(50.9±8.2)mm vs(39.9±7.1)mm vs(39.3±5.4)mm vs(39.8±7.9)mm,F=87.032,P<0.05;LV前后径(56.9±6.8)mm vs(49.0±5.8)mm vs(48.2±4.3)mm vs(48.5±6.3)mm,F=71.042,P<0.05;EDV(135.4±38.6)ml vs(99.1±30.1)ml vs(93.1±21.6)ml vs(98.6±37.3)ml,F=52.639,P<0.05;ESV(58.3±20.9)ml vs(47.7±21.3)ml vs(41.8±13.4)ml vs(44.1±25.8)ml,F=18.300,P<0.05];与术前比较,术后1个月、3个月LVEF较术前略减低[分别为(57.5±5.1)%vs(53.1±6.5)%vs(55.8±5.6)%,F=14.885,P<0.05];术后12个月与术前LVEF比较差异无统计学意义[术前(57.5±5.1)%vs(56.5±5.9)%,P>0.05]。平均随访时间为(23±10)个月,随访时所有患者均存活,无因反流复�Objective To assess the clinical value of mitral valvuloplasty under the guidance of real-time three-dimensional transesophageal echocardiography(RT3D-TEE)and its short-and medium-term effects.Methods The clinical data of 147 patients with mitral insufficiency treated by VATS from January 2016 to December 2018 were collected,including 97 males(66%)and 50 females(34%)ranging in age from 10 to 68(mean,45.8±14.5)years.RT3D-TEE was performed before operation to help surgeons choose the model of ring and surgical procedure.RT3D-TEE was performed immediately after operation to evaluate the effect of mitral valvuloplasty.Echocardiographic results were recorded during follow-up.The changes in the diameters of the left atrium(LA)and left ventricle(LV),left ventricular ejection fraction(LVEF),and mitral regurgitation or stenosis before and after operation were compared.Results There were two cases of surgical failure,in which mitral valve replacement was subsequently performed.The immediate success rate of mitral valvuloplasty was 98.6%.Echocardiography showed that there were 114 cases(78.6%)with no or minimal mitral regurgitation,19(13.1%)with mild mitral regurgitation,10(6.9%)with mild-to-moderate regurgitation,and 2(1.4%)with moderate regurgitation.There were no cases with SAM sign(anterior leaflet systolic forward motion),and eight cases had faster mitral flow velocity.Compared with the values before operation,the diameters of LA and LV,end-diastolic volume(EDV)and end-systolic volume(ESV)decreased at 1,3,and 12 months after operation[LA:(50.9±8.2)mm vs(39.9±7.1)mm,(39.3±5.4)mm,and(39.8±7.9)mm,F=87.032,P<0.05;LV:(56.9±6.8)mm vs(49.0±5.8)mm,(48.2±4.3)mm,and(48.5±6.3)mm,F=71.042,P<0.05;EDV:(135.4±38.6)ml vs(99.1±30.1)ml,(93.1±21.6)ml,and(98.6±37.3)ml,F=52.639,P<0.05;ESV:(58.3±20.9)ml vs(47.7±21.3)ml,(41.8±13.4)ml,and(44.1±25.8)ml,F=18.300,P<0.05].Compared with preoperative LVEF,the LVEF at 1 and 3 months after operation was slightly lower[(57.5±5.1)%vs(53.1±6.5)%and(55.8±5.6)%,F=14.885,P<0.05).There w
