Subclass of:
Cardiomyopathies
Definitions related to restrictive cardiomyopathy:
-
A type of heart disorder referring to the inability of the ventricles to fill with blood because the myocardium (heart muscle) stiffens and looses its flexibility. Causes include replacement of the myocardium with scar tissue, abnormal cellular infiltration of the myocardium, or deposition of a substance (e.g., amyloid) in the myocardium.NCI ThesaurusU.S. National Cancer Institute, 2021
-
Restrictive left ventricular physiology is characterized by a pattern of ventricular filling in which increased stiffness of the myocardium causes ventricular pressure to rise precipitously with only small increases in volume, defined as restrictive ventricular physiology in the presence of normal or reduced diastolic volumes (of one or both ventricles), normal or reduced systolic volumes, and normal ventricular wall thickness.Human Phenotype Ontology (HPO)The Human Phenotype Ontology Project, 2021
-
(cardiomyopathy, restrictive) A form of CARDIAC MUSCLE disease in which the ventricular walls are excessively rigid, impeding ventricular filling. It is marked by reduced diastolic volume of either or both ventricles but normal or nearly normal systolic function. It may be idiopathic or associated with other diseases (ENDOMYOCARDIAL FIBROSIS or AMYLOIDOSIS) causing interstitial fibrosis.NLM Medical Subject HeadingsU.S. National Library of Medicine, 2021
-
A disorder characterized by an inability of the ventricles to fill with blood because the myocardium (heart muscle) stiffens and loses its flexibility.Common Terminology Criteria for Adverse EventsU.S. National Institutes of Health, 2021
-
Restrictive cardiomyopathy is characterized by noncompliant ventricular walls that resist diastolic filling; one (most commonly the left) or both ventricles may be affected. Symptoms include fatigue and exertional dyspnea. Diagnosis is by echocardiography and cardiac catheterization. Treatment is often unsatisfactory and is best directed...Merck & Co., Inc., 2020
-
Restrictive cardiomyopathy (RCM) is a rare disease of the myocardium and is the least common of the 3 clinically recognized and described cardiomyopathies. Its principal abnormality is diastolic dysfunction�specifically, restricted ventricular filling.WebMD, 2019
