The Cox Maze III procedure has been simplified with the availability of tissue ablation devices; however, complications related to their use are recognized. We report a case of 45-year-old woman who underwent mitral valve repair and concomitant Cryo-Maze procedure. She had reversible right coronary artery spasm develop after the procedure demonstrated by ST-segment elevation changes and coronary angiography, which was reversed with intracoronary nitroglycerin. The region of spasm suggested it as a consequence of proximity of the right coronary artery to the right atrial ablation lines.
Cox 迷宫 III 手术已经随着组织消融设备的出现而简化；然而，与它们的使用相关的并发症也得到了认可。我们报告了一例 45 岁女性，她接受了二尖瓣修复术和同期的冷冻迷宫手术。术后出现了可逆性右冠状动脉痉挛，表现为 ST 段抬高改变和冠状动脉造影，经冠状动脉内硝酸甘油逆转。痉挛区域提示其为右冠状动脉接近右心房消融线的结果。
