Q. Can you explain Right Ventricle Enlargement?

The right ventricle (RV) is roughly triangular in shape on the PA view, with a near vertical base - apex axis. When this chamber enlarges (Fig.), there is broadening of its triangular shape. Two patterns of enlargement are generally seen. A bulge may be seen along the left heart border above the apex, formed by the enlarged ventricle. The change in contour could also be due to the enlarged RV elevating a normal LV. This causes a long prominent upper contour above the apex, and a second shorter contour turning medially below the apex. On the lateral view, an enlarged RV fills in the retrosternal clear space, owing to its anterior location.
