This review article provides a broad overview of the novelties in cardiology in 2018. Advances in interventional cardiology and cardiovascular prevention, heart failure, electrophysiology and non-invasive cardiovascular imaging have provided important new insights in the pathophysiology, diagnosis and treatment of ischemic and valvular heart disease, heart failure, rhythm disorders and cardiomyopathies. This article provides an overview of the most relevant articles published in 2018.L’année 2018 a été riche en nouveautés dans les domaines de la cardiologie interventionnelle, de l’insuffisance cardiaque, de l’électrophysiologie et de l’imagerie cardiaque. Les progrès dans ces domaines respectifs ont fourni de nouveaux outils pour le diagnostic et le traitement des cardiopathies ischémiques et valvulaires, de l’insuffisance cardiaque à fraction d’éjection réduite ou préservée, des troubles du rythme et des cardiomyopathies. Cet article fournit un aperçu des articles les plus pertinents publiés en 2018.

Early diagnosis of cardiac sarcoidosis remains difficult in the absence of specific symptoms. The evolution and prognosis of the disease are strongly correlated to an early and appropriate treatment. The multi-modality assessment based on cardiac MRI and positron emission tomography associated with computed tomography (PET/CT) has significantly improved the detection of cardiac sarcoidosis over the last two decades. These approaches appear as useful and suitable imaging strategy for the early diagnosis, the assessment of the disease extent as well as the management and therapeutic follow-up. This article is a didactic review on cardiac sarcoidosis, with a special focus on recent diagnostic and therapeutic modalities, prognosis and interest of imaging techniques.
