What is the? Difference between restrictive cardiomyopathy and constrictive pericarditis?

Intrinsic/extrinsic. Restrictive cardiomyopathy involves the heart itself becoming stiff and not filling properly which eventually can cause heart failure and need a transplant to treat. Constrictive pericarditis affects the sac around the heart entrapping the heart and causing similar symptoms but may be treated if needed by removing the sac from around the heart by surgery.
Underlying cause. Clinically similar. Both restricts filling of the ventricles. Although sometimes the echocardiogram and cardiac MRI will show findings favoring one over the other such as a thickened heart, thickened pericardium cardiac catheterization is often required. In restrictive cardiomyopathy the left ventricular pressure is higher than the right specially with fluid challenge. Similarly left atrial pressure.
PERICARDITIS. Pericarditis is inflammation with fluid accumulation and reduced cardiac output. Restrictive cardiomyopathy resist diastolic filling due to noncompliant ventricular walls.

What is the difference between restrictive cardiomyopathy and constrictive pericarditis?

Similar but differen. Constrictive pericarditis and restrictive cardiomyopathy both result in diastolic abnomlities of ventricular filling. CP can be thought of as a heart encased in a porcelain shell. In CP the ventricles fill up until the limits of the calcified pericardium (early filling) and then fill no more. In rc the heart is abnormal. Filling throughout diastole is slowed but possible. Doppler can help.

What is the difference between restrictive cardiomyopathy and constrictive pericarditis of the heart disease?

Anatomy. Restriction and constriction both involve limitation to adequate filling of the heart when the heart is relaxing. In restriction, limitation is in the muscle of the heart. In construction, the limitation is in the pericardial sac which surrounds the heart.
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.

What is the difference between constrictive pericarditis and restrictive cardiomyopathy?

Several. Constrictive pericarditis is a condition where the sac around the heart (the pericardium) becomes scarred and shrinks, which does not allow the heart to fill fully. Restrictive cardiomyopathy is a condition where the pericardium is normal, but the heart muscle itself is diseased in a way that does not allow the muscle to relax and the ventricle to fill. The treatment for each is different.

What are the differences: constrictive pericarditis and restrictive cardiomyopathy?

Different cause. Symptoms may be similar but treatment is very different. The pericardium can be opened or removed to relieve constriction but restrictive cardiomyopathy does not lend itself to a quick surgical treatment. A number of medications may ameliorate the symptoms but it is important to identify and treat the cause.

How do I diagnose the constrictive pericarditis verses restrictive cardiomyopathy?

Several. 2 d echo with doppler, rt heart catheter, and cardiac MRI can all help determine constrictive vs restrictive. Ofcourse a good history and physical should always be part of the work up.

How do physicians diagnose the constrictive pericarditis verses restrictive cardiomyopathy?

See Below. The best is either an echo doppler, MRI of the heart and pericardium or a right heart catheterization. And echo doppler can show that the e to a ratio is very high, indicative of restrictive physiology. Echo or an MRI can also show the pericardium is thick, consistent with constrictive pericarditis. The right heart cath would measure the pressure inside the heart. Presentation is similar.
Difficult. Is the heart too big or is the sac too small. Can get some hints from a ct that the sac is thick, or by history and early images that help clarify any changes.

Echocardiography. May also require cardica catheterization.
