I did some reading about restrictive cardiomyopathy and restrictive pericarditis. This indicated that it is very hard to distinguish between these two disease processes, and it may take surgery to definitively diagnose it. Do doctors biopsy myocardium/pericardium tissue during catherization(R or L)?
Or do they now do exploratory surgery similar to Laproscopy to distinguish between these disease processes instead of open heart surgery?
Thanks,
