Additional file 1 of Anaesthetic management of a large paraganglioma resection in a woman with isolated L-looped transposition of the great arteries: a case report

Additional file 1. Loops 1: Middle esophagus four-chamber view. The normal right atrium (RA) is connected to the triangular-shaped ventricle (the morphologic left ventricle) by means of mitral valve with two leaflets at a higher attachment point. The ventricle has small muscle trabeculae. The left atrioventricular valve has the lowest attachment point, suggesting tricuspid valve. The enlarged left atrium (LA) is connected to the round ventricle (the morphologic right ventricle) by the tricuspid valve, which has a thick muscular trabecula. Loops 2: Middle esophagus aortic valve long axis view. The Aorta is closer to the front of the body, and part of the normal riight ventricular structure is missing. The left atrium is enlarged and connected to the morphologic Right Ventricle (the functional left ventricle) by the tricuspid valve.

附加文件1。循环1：经食管中段四腔心切面（Middle esophagus four-chamber view）。正常右心房（right atrium, RA）通过附着点更高的双叶二尖瓣（mitral valve）连接至三角形心室（形态学左心室，morphologic left ventricle），该心室肌小梁纤细。左房室瓣附着点最低，提示为三尖瓣（tricuspid valve）。扩大的左心房（left atrium, LA）通过三尖瓣连接至圆形心室（形态学右心室，morphologic right ventricle），该心室肌小梁粗大。循环2：经食管中段主动脉瓣长轴切面（Middle esophagus aortic valve long axis view）。主动脉更贴近身体前方，部分正常右心室结构缺失。左心房扩大，通过三尖瓣连接至形态学右心室（功能左心室，functional left ventricle）。
