【摘要】：目的:本文主要是采用三維超聲心動圖技術(RT-3DE)對經射頻消融術(RFCA)治療的陣發(fā)性房顫患者左房容積動態(tài)變化情況進行實時跟蹤分析,評價其手術后效果。方法:研究對象:2014年10月至20016年10月之間,40位來我院進行治療陣發(fā)性房顫疾病的患者;治療手段:射頻消融手術(RFCA);手術開始之前的3天以及治療結束的3天后,1個月后,3及6個月后采用超聲心動圖技術進行復診檢查。手術后,對已治愈患者進行追蹤觀察,并行四次超聲心動圖檢查復查,以了解其病患處的變化情況。比較分析患者消融手術(RFCA)前后各個相應時間點的左心房相關指標改變情況�；颊邫z查時均為竇性心律。復診主要是以常規(guī)測量及RT-3DE測量為主,其包含了:左心房室的相應功能指標,左心房最小、最大的容積(LAVmin、LAVmax),左心房主動、被動的排空分數(LAAEF、LAPEF),左心房收縮前的容積(LAVp)等等。其中測量的各數據分別反映了:左心房的存儲、輔泵功能以及左心室的舒張、收縮功能。最后,計算反應左心房整體功能的左心房功能指數(LAFI)。結果:從測量的各項指標中,我們可以看出手術前后的顯著差異,手術后3天時間內LAFI及A峰值、Aa顯著下降,前者調查對象之間沒有顯著的差異,不具有統(tǒng)計學意義(p0.05),而后者的調查對象之間的差異顯著,具有統(tǒng)計學意義(p0.05);手術1個月后,患者的心室、心房各項生理功能明顯改善,差異非常顯著,具有統(tǒng)計學意義(p0.05);術后3個月LAFI、LAAEF、LAPEF、LAEF、A峰及Aa均明顯升高(P0.05),LAD及左心房容積明顯減小,差異均顯著有統(tǒng)計學意義(P0.05);術后6個月除上述變化外,S峰亦明顯增高,D峰明顯降低差異顯著(P0.05)。結論:采用經導管射頻消融術(RFCA)治愈的患者,在手術結束的三天時間內,其左心房的功能出現下降的現象;經過一個月時間后,左心房的功能慢慢開始恢復,處于一個緩慢的上升期;手術后3到6個月期間,患者的左心房輔泵、管道功能都得到了提高;采用三維超聲心動圖的技術可以準確、快速的監(jiān)測到術后患者心房的動態(tài)變化情況。
[Abstract]:Objective: to analyze the dynamic changes of left atrial volume in patients with paroxysmal atrial fibrillation treated by radiofrequency ablation (RFCA) with three dimensional echocardiography (RT-3DED). Methods: from October 2014 to October, 40 patients came to our hospital to treat paroxysmal atrial fibrillation. Methods of treatment: radiofrequency catheter ablation (RFCA) was performed 3 days before the operation and 3 days after the end of the operation. Echocardiography was used to follow up the cured patients 3 and 6 months later, and the patients who had been cured were followed up and observed after the operation. Four echocardiographic examinations were performed. In order to understand the changes of patients, the changes of left atrium related indexes before and after ablation operation were compared and analyzed. The patients were all sinus rhythm at the time of examination. The main methods of re-diagnosis were routine measurement and RT-3DE measurement. It includes the corresponding functional indexes of the left atrium, the smallest left atrium, the largest volume of LAVmin LAVmaxa, the active left atrium, the passive emptying fraction of LAAEFN LAPEFN, the volume of left atrium before contraction and so on. The measured data reflect the storage of the left atrium, respectively. Auxiliary pump function and left ventricular diastolic and systolic function. Finally, the left atrial function index (Lafi), which reflects the global function of the left atrium, was calculated. Results: from the measurements, we can see the significant difference before and after the operation. During the 3 days after operation, LAFI and A peak value Aa decreased significantly. There was no significant difference between the former and the latter, but the difference between the latter was significant (P 0.05), and one month after the operation, there was no significant difference between the two groups, and one month after the operation, there was no significant difference between the two groups. The ventricular and atrial physiological functions of the patients were significantly improved with significant difference (P 0.05), and the Lafi / LAAEFA / LAPEFA peak and a were significantly increased at 3 months after operation, and the volumes of left atrium and left atrium decreased significantly. In addition to the above changes, the S peak also increased significantly at 6 months after operation. The difference was significant (P 0.05). Conclusion: the patients cured by radiofrequency catheter ablation (RFCA) were cured within 3 days after operation. The function of the left atrium declined; after a month, the function of the left atrium slowly began to recover, in a slow upward period, and during the period of 3 to 6 months after the operation, the patient's left atrium pump, Using three-dimensional echocardiography can accurately and quickly monitor the dynamic changes of the patients' atrium after operation.
