Right ventricular (RV) function is frequently overlooked during dilated cardiomyopathy (DCM) evaluation.
To evaluate RV function in children with idiopathic DCM using relatively recent echocardiographic modalities.
We prospectively studied the cardiac function in 50 children with idiopathic DCM and 50 healthy children as a control group, using four-dimensional echocardiography (4-DE), Tissue Doppler Imaging (TDI), and two-dimensional-speckles tracking echocardiography (2-D-STE). RV EF was measured by 4-DE.
The auto left (LV) ejection fractions (EF) measured by 2-D-STE were significantly lower in the patients' group than in the control. The sphericity index was also significantly lower in children with DCM than in the control. RV EF measured by 4-DE was significantly lower in the patient's group than the control. RV S wave, e´/a' ratio, myocardial performance index (MPI), and tricuspid annular plane systolic excursion (TAPSE) were significantly impaired in children with DCM than in control. Both LV and RV global longitudinal strains (GLS) were signi
There was impairment of the RV LGS and other systolic and diastolic parameters in children with DCM. STE and TDI can help to detect the early decline of RV function.
Core Tip: Cardiomyopathies are a group of cardiac muscle disorders characterized by mechanical and/or electrical impairment that give rise to dilated, hypertrophic or restrictive pathophysiology. In the current study, we prospectively studied the cardiac function in 50 children with idiopathic dilated cardiomyopathy (DCM) and 50 healthy children as a control group using Tissue Doppler Imaging (TDI) and two-dimensional-speckles tracking echocardiography. Right ventricular (RV) ejection fractions was measured by four-dimensional echocardiography. We found impairment of the RV LGS and other systolic and diastolic parameters in children with DCM. Speckles tracking echocardiography and TDI can help to detect the early decline of RV function.
