Male Heart, Inferior View

Description

Seen from an inferior perspective, the diaphragmatic surface is dominated by the left ventricle, with the apex projecting inferolaterally to the left, while the right ventricle occupies a more anteroinferior position toward the right margin. The coronary sulcus separates atrial tissue superiorly from the ventricular mass inferiorly, and the posterior interventricular sulcus runs toward the apex between the ventricles. Epicardial coronary vessels course in these grooves, with arterial branches in red and the accompanying venous tributaries in blue tracking back toward the coronary sinus. An inferior (diaphragmatic) view matters because it corresponds to the surface that rests on the central tendon of the diaphragm and frames what you are actually looking at in subcostal echocardiography and in operative exposure when the heart is elevated. Dominance patterns come into focus here: the posterior descending artery and the posterolateral branches are judged by their course in the posterior interventricular and atrioventricular grooves, a practical point when correlating inferior wall myocardial infarction with right coronary artery versus circumflex territory and with AV nodal ischemia. Coronary venous anatomy is not an afterthought either. It drives left ventricular lead placement for cardiac resynchronization and guides retrograde cardioplegia via the coronary sinus. Use this asset for gross anatomy labs, cardiovascular physiology teaching on ventricular geometry, and for cardiology or cardiothoracic surgery figures explaining coronary artery distribution on the inferior wall. It also fits radiology and echocardiography materials that pair surface anatomy with imaging orientation, and publisher layouts that need a clean, white-background heart with clearly separated arterial and venous pathways.
