Results The lesion located at the basal segments of left lower lobe in 9 cases (90%), furthermore, 7(70%) at the posterior basal segments; The remainder 1 case (10%) was found at the posterior basal segment of right lower lobe; The lesion present as multiloculated cyst containing fluid and/or air in 7 cases(70%) without contrast enhancement of cyst wall, 3 cases (30%) presented as irregular mass with moderate enhancement, in which bronchiectasis with mucous impaction, calcification or cyst containing fluid may be seen; MRP, MIP and VR reconstructions showed anomalous branches arising from descending aorta in all 10 patients(100%) with draining into left atrium via pulmonary vein,which was consistent with surgery; Ipsilateral hilar lymphadenopathy was demonstrated in 7 cases (70%).

结果 9例（90％）病灶位于左下叶基底段，其中7例（70％）位于左下叶后基底段，1例（10％）位于右下叶后基底段；7例（70％）病灶表现为含液/气的薄壁多房囊腔，增强后囊壁无明显强化，3例（30％）表现为不规则团块，增强后有中等强化，其内有粘液嵌塞的扩张支气管，也可有钙化或液性区；MPR、MIP及VR等三维重建显示10例（100％）均为降主动脉发出异常分支供血，并通过肺静脉回流入左房，血管显示情况与手术相符；7例（70％）患侧肺门淋巴结有增大。

In the Embolic Protection in Patients with Atrial Fibrillation trial, researchers compared the current standard of therapy, anticoagulation with warfarin, to a fabric-covered expandable nitinol cage known as the WATCHMAN, which blocks blood clots that typically form in the left atrial appendage, an outpouching of the left atrium.

在房颤患者的血栓保护试验中，研究者比较了目前应用华法林抗凝的治疗，以及一种名为WATCHMAN的左心耳封闭系统（可防止左心耳内血栓的可膨胀镍钛装置）的治疗效果。

A 2. 5～5. 5 MHz transducer was used according to the acoustic depth of the heart examined. Group B was used x-ray fluoroscopy (a Philip mono-rotatable C arm X-ray equipment) as image guide with routine method reported by american college of cardiology cardiovascular technology assessment committee. TTE guiding CSC in site: The guide wire was inserted into left subclavicular vein and inferior vena cava and it was displayed clearly by TTE. The sheath could be displayed clearly too by TTE. CSC was put through the sheath into right atrium in prone position and was thoroughly showed by TTE via untypical parasternal four-chamber view.

本研究对60例心内电生理检查患者，应用TTE作为影像学引导的可行性和临床应用的方法学进行了探讨，并对5只犬TEE引导射频导管消融术时大头电极导管到位的可行性进行了动物实验研究，具体为：(1)专用冠状窦电极导管置放时TTE引导的可行研究；(2)普通电极导管置放时TTE引导的可行研究；(3)专用冠状窦电极导管和普通冠状窦电极导管置放时TTE的对比研究：(4)TTE引导His束电极导管和右室电极导管到位的临床应用研究；(5)TTE在心内电生理检查中的应用研究；(6)TEE引导射频导管消融术大头电极导管到位的实验研究。

Later, under the untypical parasternal four-chamber view which can thoroughly display the ostium of coronary sinus, the catheter was promoted further to the ostium of coronary venous sinus. Then the echocardiography technician adjusted the transducer of TTE in order to thoroughly confirm the position of the catheter tip. After confirming the position of catheter tip in the coronary venous sinus, the operator inserted the catheter into the coronary venous sinus for 3～4 mm farther. It was noted that if resistance was encountered by operator, the operation must be stopped, which was the same as x-ray fluroscopy as image guiding. TTE guiding His bundle elactric cahteter、high right atrium electric cahteter and right ventricular electric catheter in site: It is difficult using TTE singly since there are too many crossroads in inferior venous.

本研究结果显示，(1)单独应用TTE作为影像学引导进行冠状窦电极导管置放的成功率为93.8％～96.7％，并且应用TTE作为影像学引导放置专用冠状窦电极导管和普通电极导管的成功率和放置时间在统计学上无显著差异；(2)TTE作为影像学引导，除过度肥胖患者外，可完全替代X线引导进行冠状窦电极导管置放，包括鞘管和扩张管的放置、指引导丝在静脉而非动脉内的证实均可由TTE完成引导，且较X线C型臂有一定优越性；(3)TTE结合普通X线胃肠透视机作为影像学导引，可顺利完成心内电生理检查时导管的安全到位，而不需昂贵的X线C型臂，可将心内电生理检查扩大到广大的基层医院；(4)TTE较X线更易和更早期发现介入治疗的并发症如急性心包填塞等，对并发症的防治甚至挽救病人的生命至为重要；(5)动物实验研究表明，TEE可引导射频导管消融术时大头电极导管成功到位。
