CAPTIVE-The的目的，本研究是确定术前和术后左心房容积指数和尺寸与成功恢复窦性心律后的迷宫operation. METHODS四十三例谁接受了考克斯迷宫III程序永久性心房颤动与外科手术干预各种心脏病的关系进行了评估。术前和术后3个月进行超声心动图检查。43例患者中36例（83.7%）恢复并维持了窦性心律。恢复窦性心律成功组（A组）术前左心房容积指数明显小于恢复不成功组（B组：76.7 ± 16.4 vs 108.9 ± 43.9 mL/m2，P = 0.047）。A组术后3个月体积指数（76.7 ± 16.4 vs 52.3 ± 15.0 mL/m2，P <0.001）和尺寸指数（35.8 ± 6.2 vs 30.8 ± 4.7 mL/m2，P <0.001）显著降低。B组无明显变化。A组心律失常持续时间明显短于B组（3.4 ± 2.8 vs 13.7 ± 8年，P = 0.001）.结论术前左房容积指数（与传统左房尺寸相反）和心律失常持续时间是迷宫手术后成功恢复窦性心律的重要预测因素。在手术后成功恢复并维持心律的患者中，可以实现容量指数的显著降低。
OBJECTIVEThe purpose of this study was to identify the relationship of preoperative and postoperative left atrial volume indices and dimensions with successful restoration of sinus rhythm after the maze operation.METHODSForty-three patients who underwent the Cox-maze III procedure for permanent atrial fibrillation in conjunction with surgical intervention for various heart diseases were evaluated. Echocardiographic studies were performed preoperatively and 3 months postoperatively. Volumes and dimensions were corrected for body surface area and analyzed.RESULTSSinus rhythm was restored and maintained in 36 (83.7%) of the 43 patients. The preoperative left atrial volume index of the group with successful restoration of sinus rhythm (group A) was significantly smaller than that of the group with unsuccessful restoration (group B: 76.7 ± 16.4 vs 108.9 ± 43.9 mL/m2, P = .047). In group A the volume index (76.7 ± 16.4 vs 52.3 ± 15.0 mL/m2, P < .001) and dimension index (35.8 ± 6.2 vs 30.8 ± 4.7 mL/m2, P < .001) decreased significantly 3 months after the operation. No such significant changes were found in group B. The duration of arrhythmia for group A was significantly shorter than that for group B (3.4 ± 2.8 vs 13.7 ± 8 years, P = .001).CONCLUSIONSThe preoperative left atrial volume index, as opposed to the conventional left atrial dimension, and the duration of arrhythmia are important predictors of successful sinus rhythm restoration after the maze operation. A significant reduction of the volume index can be achieved in patients whose rhythm is successfully restored and maintained after the procedure.
