What is constrictive pericarditis?

Constrictive pericarditis is a condition where the pericardium, the thin membrane that holds your heart in place, becomes stiffer and thicker than normal. That interferes with your heart’s pumping ability and can lead to severe problems like heart failure. It's usually a chronic (long-term) problem, but it is treatable in most cases, especially with early diagnosis.
