Late outcomes
A total of 52 deaths (early or late) were observed over a median (IQR) follow-up period of 6.01 (3.56, 9.47) years. The overall 1-, 5- and 10-year survival was 73.6%, 53.4% and 32.1% respectively (Figure 2). The prespecified factors assessed for an unadjusted association with overall survival are presented in Table 4. Only older age was univariably associated with increased risk of mortality (per 10-year increase: HR 1.55, 95% CI 1.18-2.02; p=0.002). There was no association between ejection fraction, coronary artery disease, previous cardiac surgery, concomitant surgical procedures, or pre-operative renal failure with mortality. There was no survival advantage of performing a radical resection in this population (HR 1.35, 95% CI 0.77-2.36, p=0.295). There was also no difference in survival between patients that underwent pericardiectomy with concomitant cardiac procedures and patients that underwent isolated pericardiectomy (HR 0.70, 95% CI 0.39-1.27, p=0.246).
