"Left ventricular hypertrophy (LVH) is present when the left ventricular mass is increased. It is a common condition, typically due to systemic hypertension, and it increases with age, obesity and severity of hypertension."
"Transthoracic echocardiography is an important screening tool to detect left ventricular hypertrophy; favourable features include near universal availability, absence of ionising radiation and superb temporal resolution. Like any ultrasound-based technique, echocardiography is more dependent on the operator than CT/MRI and is more affected by patient factors."
"The left ventricular mass index is then derived; values exceeding 95 or 115 g/m2 in females and males respectively traditionally define left ventricular hypertrophy. Further stratification of both the normal and hypertrophic left ventricle then proceeds using relative wall thickness, which subdivide the former into normal ventricles and those with concentric remodelling, and the latter into eccentric and concentric hypertrophy 3."
"Cardiac MRI (CMR) is the gold standard for evaluation of left ventricular hypertrophy, with the ability to measure multiple other myocardial parameters simultaneously. Its spatial resolution is poorer than echo/cardiac CT, takes longer to perform than either echo or CT, and has relative limitations in those with implanted cardiac devices (e.g. mechanical valves, pacemakers, etc.)."
