What is difference between constrictive and restrictive?
In restrictive cardiomyopathy, reduced compliance is caused by abnormal elastic properties of the myocardium and/or intercellular matrix, whereas in constrictive pericarditis, reduced chamber compliance is imposed by the external pericardial constraint.
How does echo diagnose pericarditis?
An echo will show the classic signs of constrictive pericarditis, including a stiff or thick pericardium that constricts the heart’s normal movement. Cardiac MRI to check for extra fluid in the pericardium, pericardial inflammation or thickening, or compression of the heart.
How is constrictive pericarditis Echo diagnosed?
Since echocardiography is usually an initial diagnostic test to evaluate such patients, the following features can aid in the diagnosis of constrictive pericarditis: 1. Ventricular septal motion abnormality (from ventricular interdependence) 2. Medial mitral annulus e’ velocity ≥ 9 cm/sec 3.
Can constrictive pericarditis be seen on Echo?
Conclusions— Echocardiography allows differentiation of constrictive pericarditis from restrictive myocardial disease and severe tricuspid regurgitation.
What is the difference between restrictive and constrictive cardiomyopathy?
Constrictive pericarditis requires surgical treatment and is usually curable, while restrictive cardiomyopathy, short of cardiac transplantation, is treatable only by medical means and often responds unsatisfactorily.
Why is Y wave prominent in constrictive pericarditis?
In constrictive pericarditis, the characteristic sharp and deep y descent reflects rapid filling in early diastole which occurs when the unyielding pericardium elevates atrial pressure and limits ventricular filling to the early diastolic period.
Can you have pericarditis with a normal echo?
An echocardiogram is often ordered in patients in whom acute pericarditis is suspected. No echocardiographic feature is pathognomonic of the disease. Patients with uncomplicated viral pericarditis will have a normal echocardiogram.
What is the more specific diagnostic tool used for constrictive pericarditis?
The European Society of Cardiology recommends TTE in all patients with suspected constrictive pericarditis. A study by Welch et al indicated that echocardiography can be used to differentiate constrictive pericarditis from restrictive myocardial disease and severe tricuspid regurgitation.
What causes restrictive cardiomyopathy?
Restrictive cardiomyopathy is a rare condition. The most common causes are amyloidosis and scarring of the heart from an unknown cause. It also can occur after a heart transplant.
What is the specificity of Echocardiography in the diagnosis of constrictive pericarditis?
The specificity increased to 97% when all 3 factors were present, but the sensitivity decreased to 64%. Echocardiography allows differentiation of constrictive pericarditis from restrictive myocardial disease and severe tricuspid regurgitation.
Should restrictive pericarditis be considered a separate diagnostic entity?
CONCLUSIONS Although rare, restrictive pericarditis (restrictive ventricular physiology resulting from pericardial disease) should be considered to be a separate diagnostic entity because its pathological basis and treatment are different from intrinsic myocardial disease.
What is constrictive pericarditis?
Constrictive pericarditis is a potentially reversible cause of heart failure. Diagnosis may be challenging because the presentation can be similar to that of restrictive myocardial disease, severe tricuspid regurgitation, and some noncardiac conditions. Occasionally, these conditions may even coexist.
How is constrictive pericarditis diagnosed in patients with heart failure?
Constrictive pericarditis is a potentially reversible cause of heart failure that may be difficult to differentiate from restrictive myocardial disease and severe tricuspid regurgitation. Echocardiography provides an important opportunity to evaluate for constrictive pericarditis, and definite diagnostic criteria are needed.
