Figure 3. Left ventricular global longitudinal strain to differentiate between mutation positive sarcomeric hypertrophic cardiomyopathy and cardiac amyloidosis. In panel A, the apical 4-chamber view of a 66 year-old patient known with mutation positive hypertrophic cardiomyopathy. The thickness of the septum was 28 mm and the left ventricular ejection fraction was 55%. In panel B, the polar map shows markedly impaired longitudinal strain in the septal mid and basal areas and the global longitudinal strain is impaired (-13.6%). Panel C shows the apical 4-chamber view of a 75 year-old patient diagnosed with light chain amyloidosis. There is concentric hypertrophy of the left ventricle and the ejection fraction is 56%. Based on speckle tracking echocardiography analysis, the left ventricular global longitudinal strain is impaired (-12.2%) with typical sparing of the longitudinal strain values in the apical segments. Abbreviations: ANT, anterior; ANT_SEPT, anteroseptal; GS, global strain; INF, inferior; LAT, lateral; POST, posterior; SEPT, septal.
