[Value of cardiac MRI for intraventricular thrombi's diagnosis].
BACKGROUND
Intraventricular thrombosis is a serious event, generally complicating a wide myocardial infarction. It requires an adapted therapy, based on the oral anticoagulants. The diagnosis is generally carried out by trans-thoracic echocardiography but with an insufficient sensitivity and a specificity. In this context, the place of cardiac MRI remains to be explored.


METHODS
We carried out a retrospective registry of all cardiac MRI done in our hospital since 2003, for assessment of an intracardiac mass or an cerebral stroke. The aim was to compare the results of cardiac MRI with those of echocardiography and contrast ventriculography.


RESULTS
Our registry includes 26 cases of intraventricular thrombi, confirmed by cardiac MRI. Our results confirm the lack of sensitivity of echocardiography and the ventriculography. The Kappa correlation coefficient of echocardiography and ventriculography, with respect to the MRI, are very weak, respectively of -0.08 and 0.16.


CONCLUSIONS
The values of echocardiography and contrast ventriculography seem limited. The realization of a complementary cardiac MRI must be recommended as often as possible in case of doubt or high risk disease.
