Figure 2: Transthoracic echocardiography during follow-up in the same patient as in Figure 1. There was a reduction in the size of all cardiac chambers including left atrium and ventricle (5.7 cm × 4.0 cm; end-diastolic volume – 161 cm; end-systolic volume – 72.5 ml), with the calculated LV ejection fraction of 55% (a and c). The color flow mapping of the tricuspid valve revealed trivial tricuspid regurgitation with normal pulmonary artery pressure (b). The mitral inflow velocities showed grade I diastolic dysfunction (d). Tissue Doppler imaging demonstrated normal LV systolic and diastolic functions (e). The speckle tracking echocardiography showed that the global longitudinal strain of the LV had improved to 19.7% (f). The polar map demonstrated improvement in the regional function of the LV basal and apical segments (g). LV: Left ventricle
