(A, B, C, D) Images from a preoperative examination of a 29-year-old man who suffered from tetralogy of Fallot with atresia of the pulmonary trunk, and who had undergone reconstruction of the right ventricular outflow tract using an aortic valve-containing allograft and a Dacron prosthesis as a child. However, now the conduit was extremely calcified and partially obstructed causing right heart failure that required reoperation. (A) Volume-rendered reconstruction of the entire multislice spiral computed tomography (MSCT) data set visualizing the heart with the coronary arteries and great vessels including the implanted horse-shoe Dacron conduit which was positioned in a nonanatomic manner anterior to the aortic root. The calcification of the conduit is also visible. (B) Section through the same MSCT data set in an angulated sagittal orientation demonstrating the extreme calcification and partial obstruction (arrows) of the Dacron conduit. (C) Section through the same MSCT data set in an axial slice orientation at end-diastole (left) and end-systole (right) with the endocardial and epicardial drawings of the right ventricle. The right ventricle shows global dilatation, reduced ejection fraction, and marked hypertrophy of the myocardium. (D) Corresponding magnetic resonance images of the same patient (similar slice position as in Fig 1C at end-diastole [left] and end-systole [right]). (A = anterior; Ao = aorta; L = left; LA = left atrium; LV = left ventricle; P = posterior; R = right; RA = right atrium; RV = right ventricle.)

3. Fig 2
(A, B, C, D, E) Scatterplots showing the regression analysis between magnetic resonance imaging (MRI, horizontal axes) and multislice spiral computed tomographic (MSCT, vertical axes) measurements of the right ventricular end-diastolic volume (EDV, A), end-systolic volume (ESV, B), stroke volume (SV, C), ejection fraction (EF, D), and myocardial mass (E) for all patients. Each symbol represents data from 1 patient. Circles represent patients with compromised right heart function. Triangles represent patients with preserved normal right heart function. The regression lines (dashed lines) and the regression equation, including Pearson's correlation coefficients (r) are shown in each plot (level of significance, p < in each case).
