In that period, there were 284,860 indoor admissions to the hospital, of which 382 patients had primarily some kind of pericardial disease; of these, 40 patients with constrictive pericarditis were operated on.

The characteristic histopathological changes showing tubercles and giant cell system were seen in 30 patients.
