Incomplete Pericardial Dissection, Fluid Overload, Delayed Diagnosis And Treatment, And Tuberculosis Pericarditis Are Associated With Low Cardiac Output Syndrome Following Pericardiectomy

Background We aimed to investigate risk factors of LCOS following pericardiectomy. Methods This was a retrospective study of patients undergoing pericardiectomy at three hospitals between January 1994 and May 2021. Results A total of 826 patients were divided into two groups: group with LCOS (N = 126) and group without LCOS (N = 700). The incidence of postoperative LCOS was 15.3%. There were 66 operative deaths (8.0%). Univariable and multivariable analyses showed that factors are associated with LCOS, including postoperative LVEDD (P Conclusion In our study, incomplete pericardial dissection, fluid overload, delayed diagnosis and treatment, and tuberculosis pericarditis are associated with LCOS following pericardiectomy.
