Abstract

Atrial linear scars in Cox‐Maze IV procedures are achieved using Cryothermy (Cryo) or radiofrequency (RF) techniques. The subsequent postoperative left atrial (LA) reverse remodelling is unclear. We used 2‐ and 3‐dimensional echocardiography (2‐3DE) to compare the impact of Cryo and RF procedures on LA size and function 1 year after Cox‐maze IV ablation concomitant with Mitral valve (MV) surgery.

一项随机试验，通过二维和三维超声心动图评估低温和射频Cox-Maze IV消融对心房大小和功能的影响。冷冻或燃烧。

背景：Cox-Maze IV手术中的心房线性瘢痕是使用低温（Cryo）或射频（RF）技术实现的。随后的术后左心房（LA）反向重塑尚不清楚。我们使用二维和三维超声心动图（2-3DE）来比较Cryo和RF手术对Cox迷宫IV消融伴二尖瓣（MV）手术后1年左心房大小和功能的影响。方法：72例MV合并AF患者随机分为两组 = 35）或RF（n = 37）消融。另外33名患者未经消融（NoMaze）。所有患者均在手术前一天和手术后1年接受了超声心动图检查。结果：42例消融患者术后1年窦性心律恢复正常。他们在手术前具有可比较的左心室和右心室收缩功能、左心房容积指数（LAVI）和二维储层应变。在随访中，射频治疗后3DE提取的储液器和助推器功能更高（37 ± 10%对26 ± 6%；p 结论：无论使用何种能量来源，MV手术和迷宫后的SR恢复都会导致左心房缩小。与射频相比，Cryo产生的消融区域的扩展意味着影响左心房收缩功能的结构性左心房重塑。

期刊介绍： Clinical Physiology and Functional Imaging publishes reports on clinical and experimental research pertinent to human physiology in health and disease. The scope of the Journal is very broad, covering all aspects of the regulatory system in the cardiovascular, renal and pulmonary systems with special emphasis on methodological aspects. The focus for the journal is, however, work that has potential clinical relevance. The Journal also features review articles on recent front-line research within these fields of interest. Covered by the major abstracting services including Current Contents and Science Citation Index, Clinical Physiology and Functional Imaging plays an important role in providing effective and productive communication among clinical physiologists world-wide.
