  • Infiltrative cardiomyopathies include a range of conditions where abnormal substances are deposited within the heart muscle (myocardium), leading to pathologies such as increased wall thickness, inflammation, microvascular dysfunction, and fibrosis.
  • More advanced disease may have features such as abnormal myocardial filling, chamber dilation, and disruption of the conduction system, eventually leading to heart failure and arrhythmias.
  • Advances in non-invasive imaging techniques such as echocardiography, and nuclear and cardiac magnetic resonance imaging have improved early and accurate diagnosis of infiltrative cardiomyopathies while reducing the need for endocardial biopsy.
