Myocardial fibrosis by delayed enhancement cardiovascular magnetic resonance and HCV infection in thalassemia major patients.
2010
Abstract Abstract 4265 Introduction. Delayed enhancement (DE) cardiac magnetic resonance (CMR) technique with intravenous administration of gadolinium (Gd) chelates contrast agents is the only validated non-invasive approach for detecting myocardial fibrosis (Mahrholdt H et al, Eur Heart J 2005). This technique has been confirmed safe in patients with hemoglobinopathies (Meloni A et al, Haematologica 2009). In thalassemia major (TM), myocardial fibrosis has been detected using the DE technique and a positive correlation with anti-HCV antibodies has been described (Pepe A et al, Heart 2009). However, HCV-induced cardiomyopathy is still controversial (Matsumori A et al. J Card Fail 2006). The…

Management of chronic viral hepatitis in patients with thalassemia: recommendations from an international panel.
2010
AbstractChelation therapy with new drugs prevents cardiac damage and improves the survival of thalassemia patients. Liver diseases have emerged as a critical clinical issue. Chronic liver diseases play an important role in the prognosis of thalassemia patients because of the high frequency of viral infections and important role of the liver in regulating iron metabolism. Accurate assessment of liver iron overload is required to tailor iron chelation therapy. The diagnosis of hepatitis B virus– or hepatitis C virus–related chronic hepatitis is required to detect patients who have a high risk of developing liver complications and who may benefit by antiviral therapy. Moreover, clinical manage…
Standardized T2* map of normal human heart in vivo to correct T2* segmental artefacts.
2007
A segmental, multislice, multi-echo T2* MRI approach could be useful in heart iron-overloaded patients to account for heterogeneous iron distribution, demonstrated by histological studies. However, segmental T2* assessment in heart can be affected by the presence of geometrical and susceptibility artefacts, which can act on different segments in different ways. The aim of this study was to assess T2* value distribution in the left ventricle and to develop a correction procedure to compensate for artefactual variations in segmental analysis. MRI was performed in four groups of 22 subjects each: healthy subjects (I), controls (II) (thalassemia intermedia patients without iron overload), thala…
