Difficult diagnosis. First a few definitions because this field is fraught with poor nomenclature: acute pericarditis is most often not diagnosed by echocardiography. Chronic pericarditis which can lead to constriction (also called constrictive pericarditis) can often be suspected on echo (something called ventricular interdependence). Cardiac mri, cardiac ct and cardiac catheterization can help confirm the diagnosis.
Not always. Constrictive pericarditis may be seen with pericardial effusion or thickening ( easily seen on echo) or with a normal thickness of pericardium. In the latter case, it can be detected by echo based on its restriction of cardiac wall motion , however this can be subtle and may be confused with other conditions.
No. It can be a difficult diagnosis in some cases.
What is the difference between restrictive cardiomyopathy and constrictive pericarditis of the heart disease?
I will do my best. No one is answering you. Cardiomyopathy describes disease of heart muscle. If the heart becomes restrictive is how well it can beat by weak contraction of the muscle, this becomes restrictive cardiomyopathy. The pericardium is a sac that surrounds the heart. If it is thickened and become stiff it will restrict the expansion and contraction of the heart in a secondary manner. Best i can do. Read more...
