How to differentiate restrictive cardiomyopathy and constrictive pericarditis?





  #2

thickness

pericarditis - thick pericardium

cmp - thick/infiltrated myocardium

CT / MRI

"most best super definite" diagnosis is by biopsy

hey aspire,
good Q.
This is what i can contribute:

Const peri- calcification in pericardium
Moreover,
Apical impulse normal in rest.myo but decreased in cons.peri..

Hope it helps

"Pericardial calcification is best seen on the lateral view and is uncommon. It rarely involves the LV apex, and finding of calcification at the LV apex is more consistent with myocardial aneurysm."

"Echocardiography rarely demonstrates a thickened pericardium."

"Pericardial thickening of > 4 mm must be present to establish the diagnosis."

[CMDT]

there are some RV /LV pressure measurments differences, but i dont understand it in a quick glance in CMDT. i'll try the google

1997 NEJM -- page 7 has a table of comparison -- www.uphs.upenn.edu/medicine...ember/pdfs/restrictive.pdf
