Int J Cardiol 2022 06 30;357:55-71. Epub 2022 Mar 30.

Department of Clinical and Molecular Medicine, Sapienza University of Rome, Division of Cardiology, Sant'Andrea Hospital, Via di Grottarossa 1035-1039, 00189 Rome, Italy.

Cardiomyopathies (CMPs) are myocardial diseases in which the heart muscle is structurally and functionally abnormal in the absence of coronary artery disease, hypertension, valvular disease and congenital heart disease sufficient to cause the observed myocardial abnormality. Thought for a long time to be rare diseases, it is now clear that most of the CMPs can be easily observed in clinical practice. However, there is a group of specific heart muscle diseases that are rare in nature whose clinical/echocardiographic phenotypes resemble those of the four classical morphological subgroups of hypertrophic, dilated, restrictive, arrhythmogenic CMPs.

Multimodality Cardiac Imaging in Cardiomyopathies: From Diagnosis to Prognosis.

J Clin Med 2022 Jan 24;11(3). Epub 2022 Jan 24.

Cardiovascular Imaging Unit and Inherited Cardiovascular Diseases Unit, Cardiology Department, Hospital Universitari Vall d'Hebron, Vall d'Hebron Institut de Recerca, 08035 Barcelona, Spain.

Cardiomyopathies are a group of structural and/or functional myocardial disorders which encompasses hypertrophic, dilated, arrhythmogenic, restrictive, and other cardiomyopathies. Multimodality cardiac imaging techniques are the cornerstone of cardiomyopathy diagnosis; transthoracic echocardiography should be the first-line imaging modality due to its availability, and diagnosis should be confirmed by cardiovascular magnetic resonance, which will provide more accurate morphologic and functional information, as well as extensive tissue characterization. Multimodality cardiac imaging techniques are also essential in assessing the prognosis of patients with cardiomyopathies; left ventricular ejection fraction and late gadolinium enhancement are two of the main variables used for risk stratification, and they are incorporated into clinical practice guidelines.
