Coronary Veins, Anterior View

Description

Oriented in anterior (frontal) view, the heart is presented with the coronary venous network coursing over the sternocostal surface, with the great cardiac vein ascending in the anterior interventricular sulcus alongside the left anterior descending artery before turning left within the coronary (atrioventricular) sulcus toward the coronary sinus. Smaller venules and named tributaries are implied along the left ventricular margin, including the left marginal vein, while the anterior cardiac veins drain the right ventricle and pass directly toward the right atrium. Superiorly, the ascending aorta and pulmonary trunk frame the base of the heart, with the superior vena cava and pulmonary veins providing orientation around the atria. Green lymphatic vessels and nodal clusters surround the great vessels and pericardial reflections, distinguishing cardiac lymph drainage from the blue venous return. An anterior emphasis on the great cardiac collecting vessel matters because this is the venous channel most often encountered when correlating coronary angiography with coronary venography for cardiac resynchronization therapy planning, where a left ventricular lead may be advanced via the coronary sinus into a lateral or posterolateral venous branch. Surface relationships also anchor teaching of the “triangle of Brocq and Mouchet” region and the close pairing of the great cardiac vein with the anterior interventricular artery, a practical consideration when dissecting or mobilizing the epicardium. The lymphatic overlay supports discussion of pericarditis and postoperative mediastinal lymphatic drainage patterns. Clear landmarks. Cardiac anatomy courses, cardiothoracic surgery atlases, and interventional cardiology teaching files will benefit from this pairing of coronary veins with adjacent arterial and lymphatic pathways, especially when explaining coronary sinus cannulation, venous variations, and epicardial lead placement on the male adult heart. Suitable for lecture slides, journal figures on coronary venous access, and patient education materials on venous return and cardiac lymphatics.
