Right Ventricle, Anterior View

Description

Dominating the anterior (sternocostal) surface of the heart, the right ventricle occupies most of the anteroinferior silhouette, lying anterior to the left ventricle and inferior to the right atrium. Its free wall is positioned to the right of the anterior interventricular sulcus, with the interventricular septum forming the medial boundary toward the left ventricle. Superiorly, the right ventricular outflow tract (conus arteriosus, infundibulum) tapers toward the pulmonary trunk. Orientation is obvious. This anterior perspective matters because it mirrors what you meet after median sternotomy or anterolateral thoracotomy, when the right ventricle is the chamber most exposed and most susceptible to injury during re-entry. The relation of the conus arteriosus to the pulmonary valve and proximal pulmonary trunk also anchors teaching on right ventricular outflow tract obstruction, including the infundibular component of tetralogy of Fallot and postrepair RVOT anatomy. Surface anatomy drives decisions. Use this asset for gross anatomy and cardiothoracic surgery teaching when introducing chamber identification on the external heart, the interventricular groove as a landmark for the LAD, and the concept of right ventricular predominance on the anterior cardiac surface. It also reads well in exam-prep diagrams, patient-education materials explaining right-sided pump function, and operative atlases illustrating exposure during sternotomy.
