Left Ventricular Hypertrophy

Left ventricular hypertrophy can occur as a natural response to exercise (e.g., up to 60% increase in mass in trained rowers or cyclists), but also as a pathological reaction to hypertension and cardiovascular disease. If the stress is volume overload, eccentric hypertrophy with wall thickness increase proportional to chamber radius increase, occurs. If the stress is pressure overload, the wall thickens out of proportion to chamber size, a process called concentric hypertrophy.

Case #1. Concentric hypertrophy of the left ventricle.
