Left Border of the Heart[edit | edit source]

Anatomy of the heart, showing the left border

The left border of the heart refers to the anatomical boundary of the heart on the left side when viewed from the front (anterior aspect). It is primarily formed by the left ventricle and a small part of the left atrium.

Anatomy[edit | edit source]

The left border of the heart is formed by the left ventricle, which is the largest and most muscular chamber of the heart. It is responsible for pumping oxygenated blood to the body through the aorta. The upper part of this border is formed by the left atrium, which receives oxygenated blood from the lungs through the pulmonary veins.

Clinical Significance[edit | edit source]

Changes in the size or position of the left border of the heart can indicate various heart conditions. For example, an enlarged left border can suggest left ventricular hypertrophy, a condition where the muscle wall of the left ventricle becomes thickened.
