RESUMO
BACKGROUND: Cardiac surgery triggers a strong inflammatory reaction, which carries significant clinical consequences. Corticosteroids have been suggested as a potential perioperative strategy to reduce inflammation and help prevent postoperative complications. However, the safety and effectiveness of perioperative corticosteroid use in adult cardiac surgery is uncertain. This is an update of the 2011 review with 18 studies added. OBJECTIVES: Primary objective: to estimate the effects of prophylactic corticosteroid use in adults undergoing cardiac surgery with cardiopulmonary bypass on the: - co-primary endpoints of mortality, myocardial complications, and pulmonary complications; and - secondary outcomes including atrial fibrillation, infection, organ injury, known complications of steroid therapy, prolonged mechanical ventilation, prolonged postoperative stay, and cost-effectiveness. SECONDARY OBJECTIVE: to explore the role of characteristics of the study cohort and specific features of the intervention in determining the treatment effects via a series of prespecified subgroup analyses. SEARCH METHODS: We used standard, extensive Cochrane search methods to identify randomised studies assessing the effect of corticosteroids in adult cardiac surgery. The latest searches were performed on 14 October 2022. SELECTION CRITERIA: We included randomised controlled trials in adults (over 18 years, either with a diagnosis of coronary artery disease or cardiac valve disease, or who were candidates for cardiac surgery with the use of cardiopulmonary bypass), comparing corticosteroids with no treatments. There were no restrictions with respect to length of the follow-up period. All selected studies qualified for pooling of results for one or more endpoints. DATA COLLECTION AND ANALYSIS: We used standard Cochrane methods. Our primary outcomes were all-cause mortality, and cardiac and pulmonary complications. Secondary outcomes were infectious complications, gastrointestinal bleeding, occurrence of new post-surgery atrial fibrillation, re-thoracotomy for bleeding, neurological complications, renal failure, inotropic support, postoperative bleeding, mechanical ventilation time, length of stays in the intensive care unit (ICU) and hospital, patient quality of life, and cost-effectiveness. We used GRADE to assess the certainty of evidence for each outcome. MAIN RESULTS: This updated review includes 72 randomised trials with 17,282 participants (all 72 trials with 16,962 participants were included in data synthesis). Four trials (6%) were considered at low risk of bias in all the domains. The median age of participants included in the studies was 62.9 years. Study populations consisted mainly (89%) of low-risk, first-time coronary artery bypass grafting (CABG) or valve surgery. The use of perioperative corticosteroids may result in little to no difference in all-cause mortality (risk with corticosteroids: 25 to 36 per 1000 versus 33 per 1000 with placebo or no treatment; risk ratio (RR) 0.90, 95% confidence interval (CI) 0.75 to 1.07; 25 studies, 14,940 participants; low-certainty evidence). Corticosteroids may increase the risk of myocardial complications (68 to 86 per 1000) compared with placebo or no treatment (66 per 1000; RR 1.16, 95% CI 1.04 to 1.31; 25 studies, 14,766 participants; low-certainty evidence), and may reduce the risk of pulmonary complications (risk with corticosteroids: 61 to 77 per 1000 versus 78 per 1000 with placebo/no treatment; RR 0.88, 0.78 to 0.99; 18 studies, 13,549 participants; low-certainty evidence). Analyses of secondary endpoints showed that corticosteroids may reduce the incidence of infectious complications (risk with corticosteroids: 94 to 113 per 1000 versus 123 per 1000 with placebo/no treatment; RR 0.84, 95% CI 0.76 to 0.92; 28 studies, 14,771 participants; low-certainty evidence). Corticosteroids may result in little to no difference in incidence of gastrointestinal bleeding (risk with corticosteroids: 9 to 17 per 1000 versus 10 per 1000 with placebo/no treatment; RR 1.21, 95% CI 0.87 to 1.67; 6 studies, 12,533 participants; low-certainty evidence) and renal failure (risk with corticosteroids: 23 to 35 per 1000 versus 34 per 1000 with placebo/no treatment; RR 0.84, 95% CI 0.69 to 1.02; 13 studies, 12,799; low-certainty evidence). Corticosteroids may reduce the length of hospital stay, but the evidence is very uncertain (-0.5 days, 0.97 to 0.04 fewer days of length of hospital stay compared with placebo/no treatment; 25 studies, 1841 participants; very low-certainty evidence). The results from the two largest trials included in the review possibly skew the overall findings from the meta-analysis. AUTHORS' CONCLUSIONS: A systematic review of trials evaluating the organ protective effects of corticosteroids in cardiac surgery demonstrated little or no treatment effect on mortality, gastrointestinal bleeding, and renal failure. There were opposing treatment effects on cardiac and pulmonary complications, with evidence that corticosteroids may increase cardiac complications but reduce pulmonary complications; however, the level of certainty for these estimates was low. There were minor benefits from corticosteroid therapy for infectious complications, but the evidence on hospital length of stay was very uncertain. The inconsistent treatment effects across different outcomes and the limited data on high-risk groups reduced the applicability of the findings. Further research should explore the role of these drugs in specific, vulnerable cohorts.

Patients with submassive pulmonary embolism (PE), although normotensive, are characterized by right ventricular (RV) dysfunction and elevated levels of biomarkers of cardiac damage. The best treatment option in these cases is still a subject of debate and the use of thrombolysis in submassive PE remains controversial. A 57-year-old Caucasian male with unprovoked PE, normal blood pressure, and elevated troponin I values was referred to the cardiovascular department. In view of the presence of a right atrium thrombus, the patient underwent surgical embolectomy under extracorporeal circulation, with the extraction of a huge thrombus together with fragmented thrombi from both pulmonary arteries. The patient developed an acute right heart failure solved with a temporary RV assist device (RVAD) support. The RV recovery was observed after 72 hours following the implantation. RVAD placement should be considered in the management of PE in case of acute right heart failure after reperfusion therapy since it can bring the patient out of a death spiral.

Although Heart Transplant is still the gold standard treatment for end-stage heart failure patients, the limitation of this procedure is the discrepancy between the amount of waiting list patients and donors. Organ Care Systems, preventing the detrimental effects of cold ischemia, potentially increase donor pool. Herein we report three cases where high-risk excisions were required to clarify the nature of suspected lesions in donors. We decided to retrieve the organs and to place them in the devices before performing the excision. Our experience confirm the possibility to utilise this device as a time buffer in these peculiar scenarios.

Right ventricular primary graft dysfunction after heart transplant is a serious life-threatening condition. The severe form, refractory to maximal medical therapy, has traditionally required temporary mechanical support through veno-arterial extracorporeal membrane oxygenation or central right ventricular support. The Protek Duo is a dual lumen cannula recently introduced in the market, which allows for the institution of a percutaneous right ventricular support. We present the first promising case series of the use of this novel support in patients with right ventricular primary graft dysfunction after heart transplant.

OBJECTIVES: Prolonged aortic cross-clamp (XCT) and cardiopulmonary bypass time (CPBT) are associated with increased morbidity and mortality following cardiac surgery. The aim of this study was to assess the predictors of mortality and other severe postoperative complications in patients undergoing surgery for infective endocarditis (IE), focusing in particular on the role of prolonged XCT and CPBT. METHODS: A retrospective single-centre study was conducted from January 2000 to January 2017, including all patients undergoing valvular surgery for IE. The primary end point was early postoperative mortality. The main secondary end point was a composite end point for severe postoperative complications. RESULTS: During the study period, 264 patients were included. Early postoperative mortality was 14%. Prolonged CPBT [odds ratio (OR) 1.008, 95% confidence intervals (CIs) 1.003-1.01; P = 0.009] and increasing age (OR 1.04, 95% CI 1.01-1.07; P = 0.02) independently predicted mortality, while an inverse association was observed for left ventricular ejection fraction (OR 0.93, 95% CI 0.89-0.97; P = 0.0007). The best mortality cut-offs were >72 min for XCT and >166 min for CPBT. Prolonged CPBT also predicted severe complications, along with age, stroke, preoperative mechanical ventilation and reduced left ventricular ejection fraction. When XCT was included in the multivariable models instead of CPBT, it was associated with both mortality and severe complications. CONCLUSIONS: Prolonged XCT and CPBT are associated with mortality and development of severe complications after valvular surgery for IE. Further validation of safe limits for XCT and CPBT might provide novel insights on how to improve intraoperative and postoperative outcomes of patients with IE.

OBJECTIVES: Patients undergoing major surgery are at increased risk of developing infections due to resistant organisms, including carbapenem-resistant Klebsiella pneumoniae (CR-Kp). In this study, we assessed risk factors for CR-Kp infections after open heart surgery in a teaching hospital in northern Italy. METHODS: A retrospective study was conducted from January to December 2014. The primary outcome measure was postoperative CR-Kp infection, defined as a time-to-event end-point. The effect of potentially related variables was assessed by univariable and multivariable analyses. Secondary end-points were in-hospital mortality and 180-day postoperative mortality. RESULTS: Among 553 patients undergoing open heart surgery, 32 developed CR-Kp infections (6%). In the final multivariable model, CR-Kp colonization [hazard ratio (HR) 227.45, 95% confidence intervals (CI) 67.13-1225.20, P < 0.001], cardiopulmonary bypass time in minutes (HR 1.01, 95% CI 1.01-1.02, P < 0.001), chronic obstructive pulmonary disease (HR 3.99, 95% CI 1.61-9.45, P = 0.004), SOFA score (HR 1.29, 95% CI 1.08-1.53, P = 0.007), preoperative mechanical ventilation (HR 8.10, 95% CI 1.31-48.57, P = 0.026), prolonged mechanical ventilation (HR 2.48, 95% CI 1.08-6.15, P = 0.032) and female sex (HR 2.08, 95% CI 1.00-4.36, P = 0.049) were associated with the development of CR-Kp infection. Increased in-hospital mortality and 180-day mortality were observed in patients who developed CR-Kp infections in comparison with those who did not. CONCLUSIONS: In our cohort, CR-Kp colonization was an important predictor of CR-Kp infection after open heart surgery. CR-Kp infection after surgery significantly affected survival. Preventing colonization is conceivably the most effective current strategy to reduce the impact of CR-Kp.
