Abstract
We included 50 patients with total TOF repair with a median age of 10 years, all of them had full echocardiographic assessment and ten of them had CMR.
RV longitudinal diameter within our study group mean value was 61mm, the transverse mid RV diameter mean value was 31mm, and the RV basal diameter mean value was 31mm. RV FAC mean value was 51%, TAPSE mean value was 15, and GLS of RV mean value was -19.
The RVOT dimeter in the parasternal long axis view mean value was 25mm, in the parasternal short axis it’s mean value was 22mm, and in the subcostal inflow-outflow view the mean value was 19mm. The residual peak PG across the RVOT mean value was 35mmHg.
Thirty two of our patients (64%) had severe PR by diastolic flow reversal, fourteen patients (28%) had moderate to severe PR, and four patients (8%) had moderate PR. PR to PV annulus ratio mean value was 0.7, deceleration time of PR Doppler signal mean value was 346m sec., PR index mean value was 0.9.
In the ten patients who had CMR, the EDV mean value was 227ml, the ESV mean value was115ml, the RV EF by CMR mean value was 50%, and the PR fraction mean value was 54%.
We found that there was non significant difference between the RVOT diameters measured by TTE in the parasternal short axis and subcostal inflow-outflow views and the RVOT diameters measured by CMR.
There was a strong correlation between the RV diameters measured by TTE and RV volumes measured by CMR, according to which we could make a regression analysis equation to calculate RV volumes from a given RV diameter measured by TTE.
