【摘要】：目的：通過(guò)經(jīng)食道心臟超聲檢查測(cè)量房顫患者行射頻消融術(shù)前和術(shù)后24-48小時(shí)左心耳的相關(guān)超聲指標(biāo),評(píng)估左心耳短期內(nèi)的功能變化及左心耳出現(xiàn)血栓的風(fēng)險(xiǎn)。方法：納入2014年11月至2015年4月共28例陣發(fā)性心房顫動(dòng)患者。術(shù)前24-48小時(shí)內(nèi)行經(jīng)食道心臟超聲檢查測(cè)量左心耳最大排空速度(LAA flow emptying velocity,LAA-FEV)、左心耳最大充盈速度(LAA flow filling velocity,LAA-FFV)、左心耳最大面積(Maximum left atrial appendage,LAA max)及最小面積(Minimum left atrial appendage,LAA min),計(jì)算左心耳面積變化率(Area change rate of the left atrial appendage,LAA-EF):(LAA max-LAA min)/LAA max,并在食道超聲下觀察有無(wú)左心耳自發(fā)顯影(Spontaneous echo contrast,SEC)以及血栓。之后行房顫射頻消融術(shù),術(shù)后24-48小時(shí)內(nèi)再次行食道心臟超聲測(cè)量相同數(shù)據(jù)。結(jié)果：術(shù)前與術(shù)后相比LAA-FEV、LAA-FFV、LAA-EF未見(jiàn)明顯變化(PO.05),術(shù)后2例患者新出現(xiàn)左心耳自發(fā)顯影(P0.05)。結(jié)論：陣發(fā)性房顫患者行射頻消融術(shù)后短期內(nèi)未見(jiàn)明顯左心耳功能變化,同時(shí)有增加左心耳血栓的趨勢(shì),但無(wú)統(tǒng)計(jì)學(xué)意義。
[Abstract]:Objective: to evaluate the changes of left atrial appendage function and the risk of thrombus in left atrial appendage before and 24 to 48 hours after radiofrequency ablation in patients with atrial fibrillation by transesophageal echocardiography. Methods: from November 2014 to April 2015, 28 patients with paroxysmal atrial fibrillation were included. The maximal left atrial appendage emptying velocity (LAA flow emptying velocity,LAA-FEV), left atrial appendage maximum filling velocity (LAA flow filling velocity,LAA-FFV), left atrial appendage maximum area (Maximum left atrial appendage,LAA max) and minimum area (Minimum left atrial appendage,LAA min), were measured by transesophageal echocardiography within 24-48 hours before operation. Ear area change rate (Area change rate of the left atrial appendage,LAA-EF): (LAA max-LAA min) / LAA max, and left atrial appendage spontaneous development (Spontaneous echo contrast,SEC) and thrombus were observed under esophagus ultrasound. Then radiofrequency ablation of atrial fibrillation was performed, and esophageal echocardiography was performed 24-48 hours after operation. Results: there was no significant change in LAA-FEV,LAA-FFV,LAA-EF (PO.05) before and after operation. Spontaneous left atrial appendage was found in 2 patients after operation (P0.05). Conclusion: there was no significant change of left atrial appendage function in patients with paroxysmal atrial fibrillation after radiofrequency ablation, but there was no statistical significance.
