The internal cardiac crux is an important anatomic landmark for the appreciation of both normal and congenitally altered anatomy. The four-chamber two-dimensional echocardiographic plane of section at the internal crux is the most feasible tomographic plane. The unique noninvasive access to the internal crux anatomy is frequently more sensitive and diagnostic than other imaging modalities, including angiography. This report describes the echocardiographic and anatomic landmarks of the normal crux and the more frequent congenital anomalies that alter these relationships.
心脏内部十字交叉是理解正常及先天性解剖结构改变的重要解剖学标志。在内部十字交叉处的四腔二维超声心动图切面是最可行的断层平面。对内部十字交叉解剖结构独特的非侵入性观察，通常比包括血管造影在内的其他成像方式更敏感且更具诊断价值。本报告描述了正常十字交叉的超声心动图和解剖学标志，以及改变这些关系的更常见先天性异常。
