Definition Cardiomyopathies (CMPs) are a group of diseases with multiple etiologies and heterogeneous phenotypes, ranging from microscopic changes in cardiomyocytes asymptomatic patients to cases fulminant heart failure fluid retention, perfusion rhythm changes. A CMP was initially defined as muscle disease caused by genetic defects, myocyte injury or myocardial infiltration, characterized stru...

Arrhythmogenic cardiomyopathies are a heterogeneous group of pathological conditions that give rise to myocardial dysfunction with an increased risk for atrial or ventricular arrhythmias. Inherited defects in cardiomyocyte proteins in the sarcomeric contractile apparatus, the cytoskeleton and desmosomal cell-cell contact junctions are becoming recognized increasingly as major causes of sudden c...
