Imaging Diagnosis of Right Ventricle Involvement in Chagas Cardiomyopathy

Figure 5

Myocardial deformation analysis of right ventricle (RV) from speckle tracking echocardiography. Strain analysis of RV from representative CC patients demonstrating preserved systolic function in Panel (a) (GLS: −17.8%, FAC: 55.7%) and reduced systolic function in Panel (b) (GLS: −8.4%, FAC: 10.5). Both patients have preserved left ventricle ejection fraction. Graphics in each panel represent myocardial strain in % (superior right, yellow trace) and RV area change in cm² (inferior right, red trace). RV: right ventricle; EndoGLS: Endocardial Global Longitudinal Strain; FAC: Fractional Area Change; es: end-systolic time.
