Late gadolinium enhancement LGE cardiac magnetic resonance imaging MRI is very useful in distinguishing between myocardial infarction, in which the enhancement is typically subendocardial, and myocarditis, in which it is subepicardial Figure 1. In addition, various patterns have been described with different cardiomyopathies, in some cases enabling a specific diagnosis without invasive workup and risk stratification.

This has proved not to be the case, with cardiac MRI detecting increasing numbers of cases in patients with diastolic heart failure in whom cardiac involvement may be the first or sole manifestation.

The pattern of LGE commonly found in cardiac amyloidosis is a global subendocardial enhancement with different contrast kinetics, the ventricular cavities showing no signal at all Figures 2—6 compared to myocarditis and acute myocardial infarction, in which there is an intracavitary gray signal Figure 1.

Amiloidose cardíaca – abordagem diagnóstica, a propósito de um caso clínico.

Of 10 patients referred after cardiac raised the suspicion of a cardiomyopathy, five were diagnosed with cardiac amyloidosis, two had images not suggestive of amyloidosis and were subsequently found to have Fabry’s disease Figure 7and the other three probably had concentric left ventricular hypertrophy due to hypertension. The panel on the left is a T1-weighted image with wall thickening. Beside is the LGE image showing global subendocardial enhancement with no cavitary signal.

Biventricular global subendocardial enhancement in another patient. Note the biatrial enlargement typical of restrictive cardiomyopathies. Short-axis views of a patient with extensive global subendocardial involvement. A patient with decompensated congestive heart failure as evidenced by massive pleural effusion left had very good LV systolic function with concentric hypertrophy, while the LGE sequence right was diagnostic for amyloidosis.

The patchy involvement seen in this patient can also be seen in amyloidosis.

The decreased signal in the xardiaca cavity provides a clue. A patient initially thought to have amyloidosis is found to have no subendocardial LGE. The signal is also present in the cavity. This patient has mid-lateral wall involvement and was later diagnosed with Fabry’s disease. The authors declare that no experiments were performed on humans or animals for this study.
