Results of subtotal pericardiectomy for constrictive pericarditis.
The operative approach to constrictive pericarditis still remains a surgical challenge. Subtotal pericardiectomy through median sternotomy was analyzed retrospectively in a series of 84 patients operated on for chronic constrictive pericarditis at our institution between 1979 and 1989. The mean duration of symptoms prior to diagnosis was 20 +/- 6 months (1-264 months). Preoperatively, 72% of patients were in NYHA class III or IV, presented signs of right cardiac failure (88%) or anasarca (18%). Chest X-ray showed pericardial calcifications in 40% of the patients. Echocardiography revealed pericardial thickening in 62%. Among 62 patients in whom cardiac catheterization was performed, a characteristic dip-and-plateau was found in 47 patients (76%). A specific etiologic factor was identified in only 37 patients: tuberculosis (12%), recurrent acute pericarditis (9%), hemopericardium (9%), radiotherapy (5%), previous cardiac surgery (4%), bacterial infection (2%), myocardial infarction (2%) and connective tissue disease (2%). In 47 patients (55%), the constrictive pericarditis remained idiopathic. In seven patients we performed a redo-operation for previous incomplete pericardiectomy. Subtotal pericardiectomy (from phrenic nerve to phrenic nerve) was performed in 75 patients. A palliative procedure consisting of pericardial "meshing" was performed in nine patients due to an unsatisfactory cleavage plane. Cardiopulmonary bypass was used in four patients for coexistent cardiac lesions. The operative mortality was 2.3% (two patients: septicemia and pulmonary embolism). Seven patients (8.2%) developed early on-lethal complications. The probability of survival for patients discharged for the hospital was 94% at 3 years and 87% at 7 years. There were four late deaths and no reoperation for recurrent constriction.(ABSTRACT TRUNCATED AT 250 WORDS)
