The right ventricle (RV) possesses a complex geometry and unique functional characteristics stemming from its embryologic development. Unlike the left ventricle (LV), which arises primarily from the primary heart field, the RV originates predominantly from the anterior or secondary heart field, influencing its structural organization, myocardial fiber orientation, and contractile patterns. This embryologic origin is not only essential for understanding congenital anomalies but also profoundly impacts the interpretation and accuracy of echocardiographic modalities used to assess RV function. This review explores how knowledge of RV embryology enhances the clinical application of echocardiographic methods, including tricuspid annular plane systolic excursion (TAPSE), tissue Doppler imaging (TDI), RV fractional area change (FAC), 3D echocardiography, and RV longitudinal strain. Incorporating embryologic insights provides a more anatomically and physiologically grounded approach to evaluating RV performance, especially in congenital heart disease and right heart failure.
右心室（RV）具有复杂的几何形状和独特的功能特征，这些特征源于其胚胎发育过程。与主要起源于原始心脏区域的左心室（LV）不同，右心室主要起源于前侧或次级心脏区域，这影响了它的结构组织、心肌纤维方向和收缩模式。这种胚胎起源不仅对于理解先天性异常至关重要，而且对用于评估右心室功能的超声心动图检查方式的解读和准确性也有深远影响。本综述探讨了右心室胚胎学知识如何增强超声心动图方法的临床应用，包括三尖瓣环平面收缩期位移（TAPSE）、组织多普勒成像（TDI）、右心室面积变化分数（FAC）、三维超声心动图和右心室纵向应变。纳入胚胎学见解为评估右心室功能提供了一种更基于解剖学和生理学的方法，特别是在先天性心脏病和右心衰竭中。
