The changes in left ventricular (LV) structure and geometry that evolve after myocardial injury or overload usually involve chamber dilation and/or hypertrophy. Such architectural remodeling can be classified as eccentric or concentric. Consideration of LV volume, mass, and relative wall thickness (or mass/volume) allows classification of LV remodeling that includes virtually all LV remodeling changes that are seen in health and disease. These various architectural changes generally include the development of LV hypertrophy in a pattern that is closely related to the type of injury or overload, and they are accompanied by differences in cardiac function and hemodynamics. Some patterns of remodeling are associated with adverse outcomes whereas others appear to be adaptive and physiologic without adverse consequences. Considering all patients with LV hypertrophy as a homogenous group is inconsistent with our understanding of the various remodeling patterns that are discussed in this review.
