Aims and objectives:
Right ventricular (RV) size and volume assessment in cardiovascular magnetic resonance (CMR) is a gold standard [1,2]. CMR is of particular value in the detailed assessment of the RV, where the use of echocardiography can be limited due to problems with visualization, complex RV anatomy and motion [[...]
Methods and materials:
60 pediatric CMR studies were analysed [Table 1]. Children included in the study were representative of current routine indications for CMR. The following CMR parameters were measured: RV end-diastolic and end-systolic area (4CH EDA and 4CH ESA) [Figure 1, Figure 2], fractional area change (FAC), RV[...]
Results:
RVEDVI correlated best with 4CH ESA (r=0.85, <0.0001) and EDA (r=0.82, <0.0001). For RVEF only a moderate reverse correlation was found for 4CH ESA (-0.56, <0.0001), 4CH EDA (-0.49, 0.0001) and positive correlation for FAC (0.49, <0.0001). There was no correlation between TAPSE and RVEF [...]
Conclusion:
For routine screening in clinical daily practice, 4CH ESA seem reliable and easy method to identify patients with RV dysfunction.
