【摘要】：目的采用經(jīng)食管實(shí)時(shí)三維超聲心動(dòng)圖(RT 3D-TEE)重建二尖瓣解剖結(jié)構(gòu),探討二尖瓣環(huán)、瓣葉各參數(shù)隨心動(dòng)周期的變化規(guī)律。方法 18例陣發(fā)性房顫患者行RT 3D-TEE檢查,于左室長(zhǎng)軸觀采集3個(gè)心動(dòng)周期包含完整二尖瓣環(huán)及瓣葉的三維超聲圖像。運(yùn)用eSie Valves分析軟件獲得二尖瓣環(huán)及瓣葉各參數(shù)的動(dòng)態(tài)值。結(jié)果二尖瓣環(huán)面積、周長(zhǎng)、前后徑、連合間徑、非平面角度、主動(dòng)脈瓣環(huán)與二尖瓣環(huán)間夾角測(cè)值收縮期舒張期(P0.05),而瓣環(huán)高度、瓣環(huán)高度/連合間徑測(cè)值收縮期舒張期(P0.05);前瓣葉總面積及A1、A2、A3區(qū)面積和長(zhǎng)度收縮期舒張期(P0.05),后瓣葉總面積及P1、P2、P3區(qū)面積和長(zhǎng)度在收縮期和舒張期間的差異無(wú)統(tǒng)計(jì)學(xué)意義(P0.05)。二尖瓣各參數(shù)組內(nèi)及組間測(cè)值的一致性分析顯示一致性好。結(jié)論 RT 3D-TEE能快速定量分析二尖瓣環(huán)及瓣葉各參數(shù)隨心動(dòng)周期的變化規(guī)律,且一致性好,可為二尖瓣的修復(fù)、置換手術(shù)提供參考。
[Abstract]:Objective to reconstruct the anatomical structure of mitral valve by transesophageal real-time three-dimensional echocardiography (RT3D-TEE) and to investigate the changes of mitral annulus and lobes parameters with cardiac cycle. Methods 18 patients with paroxysmal atrial fibrillation were examined by RT 3D-TEE. Three dimensional echocardiographic images of mitral annulus and lobes were collected from 3 cardiac cycles of left ventricular long axis. The dynamic values of mitral annulus and lobes were obtained by eSie Valves software. Results the mitral annulus area, circumference, anteroposterior diameter, interconjunctival diameter, non-plane angle, the angle between aortic annulus and mitral annulus were measured in systolic diastolic phase (P0.05), and the annulus height. The total area of anterior lobe and the area and length of A _ 1 A _ 2A _ 2 A _ 3 region were measured in systolic period (P 0.05), but there was no significant difference in the area and length of posterior lobe area and P _ (1) P _ (2) P _ (3) area between systolic and diastolic period (P _ (0.05). The consistency analysis of mitral valve values within and between groups showed good consistency. Conclusion RT 3D-TEE can be used to analyze the changes of mitral annulus and lobes parameters with cardiac cycle, and the consistency is good, which can provide reference for mitral valve repair and replacement surgery.
