Tricuspid Valve Size Relationship to Right Ventricular Volume in Post-operative Tetralogy of Fallot Patients.

In post-operative Tetralogy of Fallot (TOF) patients cMRI data are used for determining right ventricle (RV) dilation to justify the pulmonary valve placement. Echocardiogram analysis of RV volumes has inherent accuracy issues. There are no data exploring the relationship of transthoracic echocardiography tricuspid valve (TV) annulus size and cMRI RV dilation.
