What Is Infiltrative Cardiomyopathy?


What does infiltrative cardiomyopathy mean?


Infiltrative cardiomyopathy is a form of cardiac muscle disease. It is featured by the accumulation of abnormal substances that make the ventricular walls progressively rigid, thereby hindering ventricular filling. The disease is marked by reduced diastolic volume of a ventricle or both ventricles with normal or almost normal systolic function.

In some cases, infiltrative cardiomyopathy increases the thickness of ventricular wall, while in others it causes chambers to enlarge. Its signs, such as increased muscle thickness, occasional dynamic left ventricular outflow obstruction, and small ventricular volume, are pretty similar to those in hypertrophic or hypertensive cardiomyopathy.
