congestive c. Myocardial disease associated with enlargement of the left ventricle of the heart and congestive heart failure.
hypertrophic c. ABBR: HCM. A heart muscle disease of uncertain cause, marked by excessive and disorganized growth of myofibrils, impaired filling of the heart (diastolic dysfunction), a reduction in the size of ventricular cavities, and often, ventricular arrhythmias heart by echocardiography or other modalities may show the heart’s enlargement to be most pronounced in the interventricular septum. Hypertrophy in that location may limit the flow of blood (and increase pressure gradients) from the left ventricle to the aorta. Abnormal anterior motion of the mitral valve during systole also may be found. These two findings are often designated on echocardiographic reports of patients with HCM by the following abbreviation: ASH-SAM (“asymmetric septal hypertrophy– systolic anterior motion” of the mitral valve).
restrictive c. A disease of the heart muscle associated with lack of flexibility of the ventricular walls. Common causes include hemochromatosis, amyloidosis, and other diseases in which the heart is infiltrated by foreign material, or scarred.
