Is right ventricular systolic function truly reduced after cardiac surgery when assessed by 3D echocardiography compared to 2D parameters?
Reductions in 2D echocardiographic parameters of RV function after cardiac surgery likely reflect geometrical changes rather than true functional decline, as 3D RVEF remains preserved.
Despite the post-operative reduction of RV performance along the long axis suggested by TAPSE and PSV, the absence of a decrease in 3D RVEF leads to caution in the interpretation of these 2D and Doppler parameters after cardiac surgery, supporting the hypothesis of geometrical rather than functional changes in the right ventricle.
