| 1 | 大螺距前门控CT扫描在房颤消融术前的应用与辐射剂量研究显示文摘目的:应用大螺距双源CT扫描房颤患者心脏,描述并测量在导管射频消融电隔离术前左房、肺静脉解剖与邻近关系及辐射剂量。方法:选择顽固性阵发性心房颤动患者30例分为两组,A组:采用HP(high pitch,大螺距)前瞻性心电门控扫描(flash spiral模式)。B组:回顾性心电门控模式扫描(spiral模式),计算两组患者扫描辐射剂量;运用二维平面测量肺动脉、上腔静脉、食管与左房一肺静脉的距离,三维重建后描述其解剖形态及与左房-肺静脉的位置关系。结果:两组扫描方式患者左房-肺静脉均显示清晰,无明显伪影。有效射线剂量:flash模式扫描有效射线剂量为(0.85±0.13)msv,Spirl扫描剂量为(13.27±3.02)msv。15例flash模式扫描中有其中7例患者冠状动脉显示清晰,图像质量好。Spiral扫描中,2例冠状动脉可诊断。肺动脉与左房顶壁平均最小距离:(4.05±2.78)mm。上腔静脉与右上肺静脉平均最小距离:(1.98±1.46)mm,食管与左房后壁上缘、中部、下缘的距离分别为(1.60±0.54),(1.34±0.47),(2.76±1.21)mm。结论:①房颤患者采用大螺距flash spirl模式与回顾性心电门控模式比较有效射线剂量低于1 mSv,图像质量无差别。②重建图像可真实反映左房、肺静脉与邻近结构的位置关系及距离。③可以清楚显示左心房和各支肺静脉的开口直径及其分支,并可发现有、无肺静脉狭窄及发育畸形。因此双源CT大螺距扫描可作为心房颤动射频消融肺静脉电隔离术前的常规影像学检查手段。 | 何桂茹 杨进军 杨君 刘艳 李江红 | 2014 | 新疆医学2014，0，4： | 2 |
| 2 | Surgical perspectives in the management of atrial fibrillation显示文摘Atrial fibrillation(AF) is the most common cardiac arrhythmia and a huge public health burden associated with significant morbidity and mortality. For decades an increasing number of patients have undergone surgical treatment of AF, mainly during concomitant cardiac surgery. This has sparked a drive for conducting further studies and researching this field. With the cornerstone Cox-Maze III 'cut and sew' procedure being technically challenging, the focus in current literature has turned towards less invasive techniques. The introduction of ablative devices has revolutionised the surgical management of AF, moving away from the traditional surgical lesions. The hybrid procedure, a combination of catheter and surgical ablation is another promising new technique aiming to improve outcomes. Despite the increasing number of studies looking at various aspects of the surgical management of AF, the literature would benefit from more uniformly conducted randomised control trials. | Katerina Kyprianou Agamemnon Pericleous Antonio Stavrou Inetzi A Dimitrakaki Dimitrios Challoumas Georgios Dimitrakakis | 2016 | World Journal of Cardiology2016，8，1： | 1 |
| 3 | Collateral findings during computed tomography scan for atrial fibrillation ablation:Let's take a look around显示文摘The growing number of atrial fibrillation catheter ablation procedures warranted the development of advanced cardiac mapping techniques, such as image integration between electroanatomical map and cardiac computed tomography. While scanning the chest before catheter ablation, it is frequent to detect cardiac and extracardiac collateral findings. Most collateral findings are promptly recognized as benign and do not require further attention. However, sometimes clinically relevant collateral findings are detected, which often warrant extra diagnostic examinations or even invasive procedure, and sometimes need to be followed-up over time. Even though reporting and further investigating collateral findings has not shown a clear survival benefit, almost all the working groups providing data on collateral findings reported some collateral findings eventually coming out to be malignancies, sometimes at an early stage. Therefore, there is currently no clear agreement about the right strategy to be followed. | Francesco Perna Michela Casella Maria Lucia Narducci Antonio Dello Russo Gianluigi Bencardino Gianluca Pontone Gemma Pelargonio Daniele Andreini Nicola Vitulano Francesca Pizzamiglio Edoardo Conte Filippo Crea Claudio Tondo | 2016 | World Journal of Cardiology2016，8，4： | 0 |
