Color Doppler Tissue Imaging for Evaluation of Right Ventricular Systolic Function in Patients with Congenital Heart Disease

New developments in echocardiographic methods to assess right ventricular function in congenital heart disease

“…Similar results were obtained by Lytrivi et al [22] who evaluated RV function in children with CHD using tricuspid annulus TDI to assess IVA and peak systolic myocardial velocity. Both variables correlated well with MRI-derived RVEF, the IVA somewhat more so.…”

Comprehensive evaluation of right ventricular function in children with different anatomical subtypes of hypoplastic left heart syndrome after Fontan surgery

“…In children, normal values for pulsed tissue Doppler imaging have been established for both left and right ventricles [7,20] and the technique has been used to assess RV function in congenital heart disease in general [8] and HLHS in particular [21]. In contrast to Frommelt et al [21], we conducted our study using colour TDI and it is important to emphasize that with this method, mean velocities within a specific region of interest (the sample volume) are displayed.…”

“…Among others, these include the myocardial performance index (MPI) [4,5], evaluation of tricuspid valve annular plane systolic excursion (TAPSE) [6] and, more recently, tissue Doppler imaging (TDI) [7]. TDI allows the interrogation of regional myocardial tissue velocities and has been shown to be a useful tool in the evaluation of RV function in children with congenital heart disease [8].…”

Echocardiographic assessment of right ventricular systolic function in conscious healthy dogs following a single dose of pimobendan versus atenolol

“…The inability of Hori et al 28 to measure a difference may be explained by a baseline depression of RV systolic function secondary to general anesthesia in their dogs prior to the administration of the esmolol, in addition to a lack of statistical power given the small number of dogs. 28 Pulsed wave TDIderived S 0 has also been shown to correlate well with radionuclide ventriculography in people with a variety of right heart diseases, 29 and with cardiac magnetic resonance (CMR)-derived RV EF in people with congenital heart disease 30 and arrhythmogenic RV cardiomyopathy. 31 Similar to S 0 , TAPSE is one of the simplest methods to assess RV longitudinal systolic function.…”
