[Discovery of left ventricular hypertrophy during adult echocardiography].

Left ventricular hypertrophy is a common finding during echocardiography. A precise evaluation of the left ventricular wall thickness, ventricular mass and distribution of hypertrophy is crucial both for diagnostic workup, follow-up and for prognostic evaluation. The differential diagnosis of left ventricular hypertrophy includes hypertrophic cardiomyopathies, hypertrophy secondary to abnormal left ventricular filling conditions, hypertrophy linked to intense physical training and the isolated basal septal hypertrophy of the elderly. Amongst the tools at the disposition of the cardiologist, regional analysis of longitudinal strain appears promising in helping distinguish cardiac amyloidosis form other forms of hypertrophy.
