迷宫术（迷宫）后，左心房转运功能恢复缓慢，但术后长期仍处于较低水平。由于迷宫留下的左心房转运功能不足，患者在迷宫后仍可能易于发生血栓栓塞。放射状切口的方法（径向）已被证明保留更大的心房运输功能比迷宫在术后早期period.MethodsTo检查后，径向的心房运输功能的系列变化，出32例接受径向，15例患者进行了评估，经胸多普勒超声心动图1，3，6，和12个月后手术。通过二尖瓣和三尖瓣的血流速度谱确定心房充盈分数和峰值A/E流速比。对21例桡动脉栓塞后随访超过3个月的患者进行了血栓栓塞事件发生率检查。结果13例患者行迷宫III术后（41 ± 6个月）左心房转运功能在3个月内明显高于行迷宫术后的水平。桡动脉后3个月的心房充盈分数为28.2% ± 7.9%，迷宫后41个月的心房充盈分数为15.1% ± 4.0%（p < 0.01）。桡动脉和迷宫术后3个月和41个月的A/E比值峰值分别为0.52 ± 0.18和0.25 ± 0.07（p < 0.01）。这种增加的心房转运功能在桡动脉后维持了很长一段时间。有没有血栓栓塞事件后的任何患者的径向或迷宫，无论术后抗凝治疗。ConclusionsThe径向的方法，防止血栓栓塞恢复足够的心房运输功能更有效，更快比迷宫。
BackgroundThe left atrial transport function recovers slowly over several months after the maze procedure (Maze), but remains at a low level even during the long-term postoperative period. Because the Maze leaves an insufficient left atrial transport function, patients may still be prone to thromboembolism after the Maze. The radial incision approach (Radial) has been shown to preserve greater atrial transport function than does the Maze in the early postoperative period.MethodsTo examine the serial change in the atrial transport function after the Radial, out of 32 patients who underwent the Radial, 15 patients were assessed by transthoracic Doppler echocardiography 1, 3, 6, and 12 months after surgery. The atrial filling fraction and peak A/E velocity ratio were determined from the flow-velocity spectra across the mitral and tricuspid valves. The incidence of thromboembolic events was examined in 21 patients who were followed for more than 3 months after the Radial. The data were compared with data obtained from 13 patients after (41 ± 6 months) the Maze III procedure.ResultsThe left atrial transport function after the Radial increased within 3 months to a significantly greater level than did that after the Maze in the long-term. The atrial filling fraction was 28.2% ± 7.9% at 3 months after the Radial and 15.1% ± 4.0% at 41 months after the Maze (p < 0.01). The peak A/E ratio was 0.52 ± 0.18 at 3 months after the Radial and 0.25 ± 0.07 at 41 months after the Maze (p < 0.01). This increased atrial transport function was maintained for an extended period after the Radial. There were no thromboembolic events in any of the patients after the Radial or Maze, irrespective of postoperative anticoagulant therapy.ConclusionsThe Radial approach prevents thromboembolism by restoring sufficient atrial transport function more effectively and faster than does the Maze.
