Abstract

Background: The purpose of this study was to review the surgical outcomes of pericardiectomy for constrictive pericarditis and to examine risk factors for overall mortality in a contemporary period. Methods: We reviewed all patients who underwent pericardiectomy for constriction from 1936 through 2013. The investigation included constrictive pericarditis cases confirmed intraoperatively, all other types of pericarditis were excluded; 1,071 pericardiectomies were performed in 1,066 individual patients. Patients were divided into two intervals: a historical (pre-1990) group (n = 259) and a contemporary (1990-2013) group (n = 807). Results: Patients in the contemporary group were older (61 versus 49 years; p < 0.001), more symptomatic (NYHA class III or IV in 79.6% versus 71.2%; p < 0.001), and more frequently underwent concomitant procedures (21.4% versus 5.4%; p < 0.001) compared with those in the historical group. In contrast to the historical cases in which the etiologies of constriction were mostly idiopathic (81.1%), nearly half of contemporary cases had a nonidiopathic etiology (postoperative 32.3%, radiation 11.4%). Although 30-day mortality decreased from 13.5% in the historical era to 5.2% in the contemporary era (p < 0.001), overall survival was similar after adjusting for patient characteristics. Risk factors of overall mortality in the contemporary group included NYHA class III or IV (HR 2.17, p < 0.001), etiology of radiation (HR 3.93, p < 0.001) or postcardiac surgery (HR 1.47, p < 0.001), and need for cardiopulmonary bypass (HR 1.35, p = 0.014). Conclusions: There was a significant change in disease etiology over the study period. Long-term survival after pericardiectomy is affected by patient characteristics including etiology of constriction and severity of symptoms.
