Abstract
Methods Ninety-five healthy volunteers, 45 patients with AndersonFabry disease (AFD), 48 with hypertension (HT), 65 with hypertrophic cardiomyopathy (HCM), 62 with severe aortic stenosis (AS), 85 with systemic amyloidosis (AMY) were enrolled. Longitudinal and transversal strain was calculated from 3 long-axis cine views, circumferential and radial strain from 3 short-axis cine images using a dedicated software (Tomtec Feature Tracking). Fourteen healthy volunteers were scanned twice, and inter-study, inter-observer, intra-observer intraclass correlation coefficients ranged between 0.36 and 0.77. Forty AS patients underwent a second scan six months after aortic valve replacement.

Myocardial strain in a health and disease: CMR feature tracking analysis in cardiac hypertrophy
We aimed to study myocardial strain in primary and secondary forms of cardiac hypertrophy, comparing it with normal values from healthy volunteers
Longitudinal and transversal strain was calculated from 3 long-axis cine views, circumferential and radial strain from 3 short-axis cine images using a dedicated software (Tomtec Feature Tracking)
