32 Volume overload and RV Function: cmri

33 Volume overload and RV Function: cmri cmri is the reference method for assessment of RV volumes and EF Analysis is based on the method of disc summation

34 Volume overload and RV Function: cmri Limitations: Limited availability High costs Time-consuming acquisition and analysis No solid data on cmri Variables in TR Bleeker et al. Heart 2006;92 Suppl 1:i19-26 Babu-Narayan et al. J Cardiovasc Med 2007;8:23-29

36 RV Remodeling determines TV Geometry and the Severity of Functional TR: 3D Echo Conclusion: Functional TR severity is determined by septal-lateral annulus and RV dilation, and tenting of septal and anterior leaflets. TV leaflet tenting is mainly determined by septallateral RV inlet dilation, and tricuspid annulus dilation is closely linked with inlet RV dilation. Song JM et al., Korean Circ J 2010; 40:

37 Take home TR may be functional (increased RV afterload) or result from intrinsic TV disease Important to detect (and treat) cause of functional TR Pressure overload poorly tolerated by RV Chronic volume overload of RV is detrimental and is associated with poor prognosis RV end-systolic dimensions and RV Function are independent predictors of outcome after TVR cmri: reference method for RVEF, but no data on TR 3D echo: function and geometry

38 Take home TR may be functional (increased RV afterload) or result from intrinsic TV disease Important to detect (and treat) cause of functional TR Pressure overload poorly tolerated by RV Chronic volume overload of RV is detrimental and is associated with poor prognosis RV end-systolic dimensions and RV Function are independent predictors of outcome after TVR cmri: reference method for RVEF, but no data on TR 3D echo Timely repair may be advised in patients with severe, isolated TR, before the development of significant RV dilatation and dysfunction
