Remodeling has three patterns. Concentric remodeling where there is an increase in relative wall thickness (ventricular wall thickness compared to cavity size) and with or without increase cardiac mass. Eccentric hypertrophy where there is an increase in cardiac mass and chamber volume with relative wall thickness varying between being decreased, the same or increased. This change is noticed in cases of volume overload, after infarction and isotonic exercise. Mixed concentric and eccentric changes as in myocardial infarction (MI), Where there is a combined volume and pressure overload on noninfarcted areas.
