Internal Sectional Cut of the Right Ventricle

Description

Anterior sectional anatomy of the right ventricle is presented with the ventricular cavity opened to expose the trabeculae carneae along the free wall and apex, contrasted against the smoother outflow region of the infundibulum (conus arteriosus) positioned superiorly. Medially, the interventricular septum forms the inner boundary of the right ventricular chamber, while the inflow tract lies more inferior and posterior relative to the pulmonary outflow. Superior and leftward in the field, the right ventricular outflow tract narrows toward the pulmonary valve region. Clear spatial orientation. That cut face matters when you need to teach or plan around right ventricular flow dynamics and the internal landmarks that guide interventions. Congenital lesions such as tetralogy of Fallot often involve subpulmonic (infundibular) stenosis, and this perspective helps separate obstruction in the muscular outflow tract from valvular pulmonary stenosis. It also supports discussion of right ventricular remodeling in pulmonary hypertension, where hypertrophy and altered trabeculation can complicate catheter navigation and imaging interpretation. Cardiology and gross anatomy courses use this plate to contrast right ventricular inflow versus outflow morphology and to reinforce the septal relationship important in ventricular septal defect classification. It also fits surgical and interventional teaching materials covering right ventriculotomy, right ventricular outflow tract reconstruction, and echocardiographic correlation (parasternal short axis and RV outflow views) for pulmonary valve assessment.
