Q. Explain Left Ventricle Enlargement?

The left ventricle (LV) is ellipsoid in shape. It lies behind, and to the left of the right ventricle. Its long axis lies at about 45 degrees to the vertical. When this chamber enlarges, all its diameters increase, but particularly its long axis. This results in a downward displacement of the apex. On the PA view this causes the left ventricular border to elongate, and move downwards or outwards or both. On the lateral view, the chamber may extend posterior to the esophagus. Its posteroinferior border may project behind the IVC at a point 2 cm above the diaphragm (Hoffman Rigler sign). The changes in cardiac contour produced by left ventricular enlargement on all four views are shown in Figure.
