This study aimed to assess the effect of levosimendan on postoperative LCOS in the patients with constrictive pericarditis.Methods: Patients were retrospectively enrolled, and those receiving the treatment of levosimendan were assigned in the LEVO (+) group, and others were in the LEVO (-) group. Postoperative outcomes including durations of intubation, vasoactive agents using, ICU stay, hospital stay and mortality were compared between the two groups.Results: A total of 32 patients were eligible for analysis, 19 of whom were in the LEVO (+) group, and 13 of whom were in the LEVO (-) group. The LEVO (+) group was associated with shorter postoperative duration of intubation (P < 0.001), vasopressor using (P = 0.006), ICU stay (P = 0.001) and hospital stay (P = 0.042), and less incidence of acute liver or kidney injury (P = 0.046). There were no significant differences in 30-day mortality and 1-year mortality between the LEVO (+) group and the LEVO (-) group. The prevalence of adverse events in the LEVO (+) group was acceptable.Conclusion: Levosimendan could be administered in the patients with constrictive pericarditis developing LCOS after pericardiectomy to enhanced postoperative recovery.Keywords: levosimendan, low cardiac output syndrome, constrictive pericarditis, pericardiectomy
