[Long-term late results of pericardiectomy for constrictive pericarditis]. 1997
Twenty-four cases of the constrictive pericarditis were operated on pericardiectomy from 1966 to 1990. One case died because of massive bleeding, LOS, and respiratory failure immediately after the operation. A long-term follow up study was performed up to 27 years (mean 13.1 years) in other cases. Ten cases died during the follow up period (cardiac: 6, non cardiac: 4). Five cases of the cardiac deaths had major complications: tabes dorsalis, chronic respiratory failure, pacemaker implantation, mitral regurgitation, emergency operation at high age (78 years old). The survival rates of 5, 10, and 15 years were 85%, 67%, and 58.2%, respectively (Kaplan-Meier). All of survival cases are now in NYHA I or II class in satisfactory. We concluded that pericardiectomy is a very effective treatment for constrictive pericarditis but a more careful follow up is required especially in cases complicated with other major problems because cardiac function is not so recovered as normal level after surgery due probably to readhesion and fibrotic changes of the myocardium.
