The authors compared the diagnostic value of magnetic resonance imaging (MRI), echocardiography and cardiac catheterisation with angiography in 66 patients with congenital heart disease, to determine a diagnostic strategy in the use of these methods of cardiac imaging. The patients were 8 days to 44 years old. The congenital cardiac malformations were classified in three groups: 29 isolated vascular malformations (Group 1), 17 isolated intracardiac malformations (Group 2) and 20 complex malformations (Group 3). MRI was performed in all patients using a high field (1.5 tesla) magnet and spin-echo sequences in multiple incidences. The results were compared with those of echocardiography in 60 patients and/or cardiac catheterisation in 39 cases. Technical evaluation of MRI showed images of diagnostic quality in 62/66 cases (93.9%). MRI provided a diagnostic contribution in 56 cases (85%) which was less important in intracardiac malformations than in the other groups (p less than 0.05). In comparison with other imaging techniques, globally, the diagnostic value of MRI was lower than that of cardiac catheterisation (p less than 0.005) but there was no significant difference between MRI and echocardiography. When the type of malformation was taken into account, MRI was not as useful as catheterisation and echocardiography for the diagnosis of isolated intracardiac malformations (p less than 0.01) but gave comparable results in other malformations. On the other hand, MRI associated with echocardiography was more useful (p less than 0.05) than catheterisation in the diagnosis of complex congenital lesions.(ABSTRACT TRUNCATED AT 250 WORDS) |
