Abstract
A retrospective analysis was undertaken in 79 patients who underwent pericardiectomy for chronic constrictive pericarditis from January 1985 to February 1999. Most operations (77) were carried out with cardiopulmonary bypass, with subtotal pericardiectomy in 75 patients, and concomitant operations in 25. Postoperative complications occurred in 8 patients: cerebrovascular accident in 2, renal insufficiency in 5, bleeding in 2, low output syndrome in 4, and respiratory insufficiency in 2. The operative mortality was 5%; causes of death were cardiac-related in all cases. Actuarial survival at 1, 5, and 10 years was 89.9% ± 3.4%, 74.9% ± 5.7%, and 55.4% ± 13.5%, respectively. Regression analysis was performed using 53 clinical variables. Female gender, renal insufficiency, concomitant coronary artery bypass grafting, and preoperative right ventricular end-diastolic pressure > 20 mm Hg were found to be predictors of poor survival. At follow-up, improved functional status was noted in 88% of patients. Subtotal pericardiectomy can be performed on cardiopulmonary bypass with low mortality and good long-term survival.
