Right ventricular speckle tracking assessment for differentiation of pressure ‐ versus volume‐overloaded right ventricle
ConclusionIn this study, RVGLS and RV‐free could more accurately discriminate RV pressure from volume overload than conventional measures. The reason could be that TAPSE and S′ are unable to differentiate active deformation from passive entrainment caused by the left ventricle. The pressure group had evidence of marked RV hypertrophy despite standard functional parameters (TAPSE and S) within normal range. This would enhance the value of strain to more sensitively detect abnormal function. A cut‐off value of below −16% for RVGLS and RV‐free predicts RV pressure overload with high accuracy.
