[Cardiac imaging in infiltrative cardiomyopathies. What cardiovascular imaging modalities to propose in hypertrophic cardiomyopathies ?]

[Cardiac sarcoidosis revealed by recurrent ventricular tachycardia]

Sarcoidosis is an inflammatory disease whose diagnosis is suggested by clinical and paraclinical signs and confirmed by histological evidence showing granulomatosis without caseous necrosis. The clinical presentation is sometimes misleading and the diagnosis difficult to confirm. We report here the case of a young woman with cardiac sarcoidosis of difficult diagnosis, revealed by a myocardial infarction with normal coronary angiography and recurrent ventricular tachycardia. Multimodal imaging, combined with left ventricular endomyocardial biopsies guided by electrophysiological analysis and endocavitary mapping, finally confirmed the diagnosis, and allowed effective medical treatment.

[Heart imaging by CT-scan and MRI in cardiac tumors]

The etiology of cardiac masses is often oncological or thrombotic, rarely inflammatory. Among heart tumors, the vast majority are metastatic. We describe the most frequent benign primary cardiac tumors and the most frequent malignant primary cardiac tumors and give information about the advantages of using a multi-modality approach for the accurate diagnosis of a cardiac mass using Computed Tomography Scanner and Magnetic Resonance Investigation.
