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 < 0.001), preoperative LVEDD (P < 0.001), time between symptoms and surgery (P < 0.001), thickness of pericardium (P < 0.001), intubation time (P = 0.002), hospitalized time postoperative (P < 0.001), preoperative central venous pressure (P = 0.016), postoperative central venous pressure (P = 0.034), D0 fluid balance (P = 0.019), D2 fluid balance (P = 0.017), postoperative chest drainage (P < 0.001), surgical duration (P < 0.001), bleeding during operation (P = 0.001), serum creatinine 24h after surgery (P < 0.001), serum creatinine 48h after surgery (P = 0.017), fresh-frozen plasma (P = 0.005), packed red cells (P = 0.006), and tuberculosis pericarditis (P = 0.026). CONCLUSION: In our study, incomplete pericardial dissection, fluid overload, delayed diagnosis and treatment, and tuberculosis pericarditis are associated with LCOS following pericardiectomy.

Analysis of Risk Factors of Early Mortality After Pericardiectomy For Constrictive Pericarditis.

BACKGROUND: We aimed to investigate risk factors of early mortality following pericardiectomy. METHODS: This was a retrospective study of patients undergoing pericardiectomy between January 1994 and May 2021 at The People's Hospital of Guangxi Zhuang Autonomous Region, Ruikang Hospital Affiliated to Guangxi University of Chinese Medicine, and The People's Hospital of Liuzhou City. RESULTS: This study included 826 patients, who were divided into two groups: group with operative deaths (N = 66) and group without operative deaths (N = 760). There were 66 operative deaths (66/826, 8.0%). The causes of operative deaths were multiorgan failure (86/826, 10.4%). Preoperative CVP (P < 0.001), chest drainage (P < 0.001), surgical duration (P < 0.001), fluid balance postoperative day D2 (P < 0.001), and tuberculosis pericarditis (P = 0.001) in group with operative deaths were significantly higher than those in group without operative deaths. Univariate and multivariate analyses showed that factors associated with operative deaths include male (P < 0.001), age (P < 0.001), ICU retention time (P < 0.001), postoperative hospitalization time (P < 0.001), preoperative central venous pressure (P = 0.018), postoperative central venous pressure (P < 0.001), D0 fluid balance (P < 0.001), D2 fluid balance (P < 0.001), postoperative chest drainage (P = 0.029), surgical duration (P = 0.003), serum creatinine baseline (P = 0.002), serum creatinine 24h after surgery (P < 0.001), serum creatinine 48h after surgery (P < 0.001), blood lactate (P < 0.001), and tuberculosis pericarditis (P = 0.033). CONCLUSION: In our study, incomplete pericardial dissection, fluid overload, and tuberculosis pericarditis are associated with operative deaths following pericardiectomy.

Analysis of risk factors of multiorgan failure after pericardiectomy for constrictive pericarditis.

BACKGROUND: We aimed to investigate risk factors of multiorgan failure following pericardiectomy. METHODS: This was a retrospective study of patients undergoing pericardiectomy between January 1994 and May 2021 at three hospitals. RESULTS: 826 patients were included in the study and divided into two groups: group with multiorgan failure (n = 86) and group without multiorgan failure (n = 740). There were 86 patients with multiorgan failure (86/826, 10.4%). There were 66 operative deaths (66/826, 8.0%). The causes of operative deaths were multiorgan failure, including cardiogenic shock + AKI + ventricular fibrillation (13/66), cardiogenic shock + AKI (35/66), cardiogenic shock + AKI + hepatic failure + septicemia (8/66), cardiogenic shock + AKI + respiratory failure (10/66). Univariate and multivariate analyses showed the factors associated with multiorgan failure, including male (P = 0.006), time between symptoms and surgery (P < 0.001), thickness of pericardium (P < 0.001), intubation time (P < 0.001), ICU retention time (P < 0.001), hospitalized time postoperative (P < 0.001), preoperative central venous pressure (P < 0.001), postoperative central venous pressure (P < 0.001), D0 fluid balance (P < 0.001), D2 fluid balance (P < 0.001), postoperative chest drainage (P < 0.001), preoperative LVEDD(P < 0.001), postoperative LVEDD (P < 0.001), surgical duration (P < 0.001), bleeding during operation (P < 0.001), serum creatinine 24 h after surgery (P = 0.042), serum creatinine 48 h after surgery (P < 0.001), fresh-frozen plasma (P < 0.001), packed red cells (P < 0.001), blood lactate (P < 0.001). CONCLUSION: In our study, incomplete pericardial dissection, fluid overload, delayed diagnosis and treatment are associated with multiorgan failure following pericardiectomy.
