Repaired Tetralogy of Fallot: Ratio of Right Ventricular Volume to Left Ventricular Volume as a Marker of Right Ventricular Dilatation

Abstract

The RV/LV ratio is more accurate than the RVEDVi in differentiation of significant from insignificant PR. After TOF repair, female and male patients have similar RV/LV ratios despite significant differences in RVEDVi between the sexes.

Determinants of left- and right‑ventricular ejection fractions in patients with repaired tetralogy of Fallot: a cardiac magnetic resonance imaging study

“…8 The presence of the RV outflow tract (RVOT) aneurysm or akinesia was assessed as described previously. 2 Data on inter-and intraobserver variability of the measurements of ventricular volumes and PR were published previously 10,12 and were comparable to those from other centers.…”

“…Selected data on patients with repaired TOF undergoing CMR imaging study in our center were published previously. [9][10][11][12] In particular, we previously analyzed factors associated with biventricular dysfunction in the same study population (31 patients with biventricular dysfunction and 65 patients with normal biventricular systolic functions were selected out of a group of 146 patient; unpublished data).…”

“…10,26 In the univariate analysis, RVOT aneurysm/ akinesia showed a negative association with RVEF. However, in the multivariate analysis, remains unexplained.…”

Alternation of Right Ventricular Contraction Pattern in Healthy Children

“…6,7 Standard RV Performance and Pulmonary Vascular Resistance We used RV stroke volume (RVSV) as a geometry-independent indicator of RV performance. RVSV was determined as the longed myocarditis due to Kawasaki disease.…”

Right Ventricular Remodeling Due to Pulmonary Regurgitation Is Associated With Reduced Left Ventricular Free Wall Strain in Surgically Repaired Tetralogy of Fallot

“…As for the r-TOF group, the RV/LV EDVI ratio (1.55±0.56) in the present study was similar to those in previous reports. 22 Zhang et al reported that the correlations between 3-D echocardiography and cMRI measurements were acceptable. 23 In our next step, we will compare RV volume obtained on 3D-TTE with that on cMRI to validate the accuracy and reproducibility.…”
