Abstract
A substantial number of patients may experience systemic inflammatory response syndrome (SIRS) and related adverse events after transcatheter aortic valve implantation and endovascular aortic aneurysm repair. Although a clear etiology has not been established, endothelial disruption and tissue-ischemic response secondary to the foreign material may represent the trigger events. A latency period (0 to 48 hours) may occur between the initial injury and onset of symptoms mirroring an initial local response followed by a systemic response. Clinical presentation can be mild or severe depending on external triggers and characteristics of the patient. Diagnosis is challenging because it simulates an infection, but lack of response to antibiotics, negative cultures are supportive of SIRS. Increased in-hospital stay, readmissions, major cardiovascular events, and reduced durability of the device used are the main complications. Treatment includes non-steroidal anti-inflammatory drugs or corticosteroids. In conclusion, further studies are warranted to fully explore pathophysiologic mechanisms underpinning SIRS and the possibility of enhancing device material immune compatibility to reduce the inflammatory reaction of the host tissue.

[PMID: 38286152 DOI: 10.1016/j.jvs.2024.01.200] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/03/2023] [Revised: 01/11/2024] [Accepted: 01/21/2024] [Indexed: 01/31/2024]
Abstract
OBJECTIVE The aim of this study was to investigate the correlation between post-implantation syndrome (PIS) and long-term prognosis in patients with Stanford type B aortic dissection (TBAD) undergoing thoracic endovascular aortic repair (TEVAR). METHODS This retrospective study included 547 consecutive patients diagnosed with TBAD who underwent TEVAR at our institution between January 2014 and December 2019. Patients were categorized into two groups: the PIS group (patients with post-TEVAR PIS) and the non-PIS group (patients without post-TEVAR PIS). In-hospital and follow-up data were analyzed. RESULTS The incidence of PIS was 28.9% (158/547 patients). No baseline differences were observed between the PIS (n = 158) and the non-PIS (n = 389) groups. The proportion of emergency surgery in the PIS group was higher than that in the non-PIS group (44.9% vs 26.0%; P < .001), the operation time was longer (median, 65.0; interquartile range [IQR], 56.0-75.0 minutes vs 56.0; IQR, 45.0-66.0 minutes; P < .001), the volume of contrast medium used (median, 65.0; IQR, 56.0-75.0 mL vs 56.0; IQR, 45.0-66.0 mL; P < .001), and the average number of trunk stents (1.85 ± 0.4 vs 1.34 ± 0.5 pieces; P < .001) and branch stents (0.7 ± 0.7 vs 0.2 ± 0.5 pieces; P < .001) used were more in the PIS group than in the non-PIS group. The incidence of supra-aortic branch procedures was higher in the PIS group than in the non-PIS group. There was no significant difference in device-related complications (DRCs) or 30-day mortality between the two groups (2.5% vs 4.4%; P = .442 and 1.3% vs 1.3%; P = .688, respectively). Univariate and multivariable logistic regression analysis showed that emergency surgery, number of trunk stents >1, operation time >58.5 minutes, and contrast medium volume >75 mL were risk factors for PIS, and the odds ratios of emergency operation, number of trunk stents >1 piece, operation time >58.5 minutes, and contrast medium volume >75 mL were 2.526 (95% confidence interval [CI], 1.530-4.173), 4.651 (95% CI, 2.838-7.624), 3.577 (95% CI, 2.201-5.815), and 7.356 (95% CI, 4.111-13.160), respectively. Follow-up was completed in 98.5% (532/540) of the patients, with a median follow-up of 67 months (IQR, 50-86 months). There was no significant difference in survival between the PIS and non-PIS groups (12.4% vs 10.3%; P = .476) during follow-up. The incidences of DRCs (7.8% vs 11.6%; P = .200) and aortic false lumen thrombosis (75.8% vs 79.2%; P = .399) were comparable between the PIS and non-PIS groups. Univariate logistic regression analysis showed that PIS had no effect on long-term follow-up mortality, DRCs, entry flow, or aortic false lumen thrombosis rate. CONCLUSIONS PIS is relatively common after TEVAR and emergency surgery; number of trunk stents >1, operation time >58.5 minutes, and contrast medium volume >75 mL are of high predictive value for the assessment of PIS after TEVAR. However, PIS had little effect on early and late postoperative mortality or DRCs.

Tumour necrosis factor-alpha serum level is an independent predictor of medium-term all-cause mortality after transcatheter aortic valve replacement. Acta Cardiol 2024; 79:114-122. [PMID: 38375765 DOI: 10.1080/00015385.2023.2223012] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/19/2022] [Accepted: 05/31/2023] [Indexed: 02/21/2024]
Abstract
BACKGROUND Transcatheter aortic valve implantation (TAVI) is a suitable treatment for patients with severe aortic stenosis and severely increased operative risk. There is need for a better preoperative risk assessment for TAVI candidates. AIM To determine whether Tumour necrosis factor-alfa (TNFα) is an independent predictor of survival 500 days after TAVI. METHODS Sixty patients undergoing TAVI were enrolled in the study. TNFα was determined. The CT measured low-density muscle fraction (LDM%) of the psoas muscle was determined. Operative risk assessment by Logistic EuroSCORE, EuroSCORE II, and STS score was performed. Frailty scores (FRAIL scale and Barthel index) were determined. RESULTS Mean age was 81.01 ± 7.54 years. Twenty-six (43.3%) of the patients were males. In the univariable analyses, FRAIL scale and Barthel index were no predictors of survival after TAVI. In the multivariable analysis, including EuroSCORE II, LDM% and TNFα serum concentration, TNFα serum level was an independent predictor of survival 500 days after TAVI (HR: 3.167; 95%: 1.279-7.842; p = 0.013). The multivariable analysis, including TNFα as a categorical variable, showed that compared to patients in the conjugated first and second TNFα serum level tertile, patients in the third tertile had a hazard ratio (HR) of 10.606 (95%CI: 1.203 - 93.467) (p = 0.033). CONCLUSION TNFα is an incremental independent predictor of long-term survival after TAVI.

Abstract
OBJECTIVE Our aim was to determine the risk factors of postoperative systemic inflammatory response syndrome (SIRS) in patients with transcatheter aortic valve replacement (TAVR), identify those with a high risk of SIRS, and help reduce SIRS occurrence. METHODS A retrospective cohort study was conducted to collect the clinical data of patients who underwent TAVR from January 2014 to December 2019 at a tertiary hospital in Zhejiang Province. The study included 156 men and 94 women. Patients were divided into SIRS and non-SIRS groups. The pre-, intra-, and postoperative indices of the two groups were recorded. The data of the two groups were compared, and univariate analysis was performed. All statistically significant factors were assessed using binary logistic regression analysis to clarify the risk factors of SIRS after TAVR. RESULTS Overall, 30 patients developed SIRS after TAVR, with an incidence rate of 12%, an odds ratio (OR) of 0.571, and a 95% confidence interval (CI) of 0.469-0.694 (p = 0.000). There was a significant correlation between SIRS and glucose (OR: 0.823, 95% CI: 0.678-1.000, p = 0.049), albumin (OR: 0.938, 95% CI: 0.881-0.998, p = 0.044), brain natriuretic peptide (OR: 1.000, 95% CI: 1.000-1.000, p = 0.010), sex (OR: 0.412, 95% CI: 0.190-0.892, p = 0.025), and history of hypertension (OR: 0.375, 95% CI: 0.169-0.819, p = 0.014). Multivariate regression analysis demonstrated that age (OR: 1.190, 95%CI: 1.073-1.319, p = 0.001) and body mass index (BMI; OR: 0.559, 95% CI: 0.447-0.698, p = 0.000) were independent risk factors for postoperative SIRS in patients with TAVR. CONCLUSION The incidence of SIRS after TAVR was 12%. There was a significant correlation between SIRS and albumin, glucose, and hypertension. The independent risk factors for SIRS after TAVR were age and BMI.

Abstract
AIMS Systemic inflammatory response syndrome (SIRS) could affect mortality after transcatheter aortic valve implantation (TAVI) up to 12 months of follow-up. The aim of this study was to evaluate the prevalence of SIRS after TAVI and its impact on all-cause mortality up to 24 months follow-up. METHODS We retrospectively enrolled 132 patients with symptomatic severe aortic stenosis undergoing TAVI. SIRS development during the first 72 h after the intervention was evaluated. Other postoperative complications were defined according to the Valve Academic Research Consortium 2 (VARC2). All patients underwent follow-up at 30 days and 24 months. Endpoints were 30-days and 24-months mortality. RESULTS Post-TAVI SIRS developed in 27 patients (20%). At 30-day follow-up, all-cause death occurred in 10 (8%) patients and SIRS occurred more frequently in patients with adverse short-term outcome (60 vs. 17%; P = 0.001). Twenty-four months all-cause death occurred in 25 (19%) patients. SIRS resulted as an independent predictor of long-term outcome [hazard ratio 3.7; 95% confidence interval (95% CI) 1.5-9; P = 0.004], along with major vascular complications (hazard ratio 4; 95% CI 1.6-9.9; P = 0.003), relevant bleedings (hazard ratio 6.4; 95% CI 1.5-28; P = 0.013) and baseline pulmonary hypertension (hazard ratio 2.4; 95% CI 1.05-5.6; P = 0.039). CONCLUSION Postoperative SIRS was more frequent in patients who died at 30 days follow-up. Moreover, SIRS resulted as a predictor of 24-month mortality along with vascular complications, relevant bleedings and baseline pulmonary hypertension.

Relation of Preprocedure Platelet-to-Lymphocyte Ratio and Major Adverse Cardiovascular Events Following Transcatheter Aortic Valve Implantation for Aortic Stenosis. Am J Cardiol 2022; 163:65-70.

Abstract
The platelet-to-lymphocyte ratio (PLR) is a novel inflammatory biomarker that has prognostic value in patients presenting with acute coronary syndrome. Transcatheter aortic valve implantation (TAVI) treats the inflammatory disease of aortic stenosis. However, the utility of preprocedure PLR in predicting major adverse cardiovascular events (MACE) after TAVI is not clear. Our study population included 470 patients who underwent TAVI at The Alfred Hospital in Melbourne, Australia from August 2008, to January 2019. Patients were divided into 4 groups based on PLR quartiles. The incidence of 30-day MACE (a composite of stroke, myocardial infarction, and death) was then compared. Outcomes were reported according to the Valve Academic Research Consortium-2 criteria. Of 470 patients, median age 84 years, 54% men, and median Society of Thoracic Surgeons score of 3.5%, 14 (3%) suffered a MACE within 30 days. Rates of MACE were low in all 4 groups (1.7%, 2.5%, 2.6%, 5.1%, respectively) with no statistically significant difference in the different PLR groups (p = 0.46). This nonsignificant association was supported by univariate logistic regression analysis of PLR as a continuous variable (odds ratio 1.01, p = 0.55). Using multivariable logistic regression analysis accounting for age, gender, self-expanding valve, and procedural risk, a higher PLR did not correlate with MACE (odds ratio 1.01, p = 0.60). In this study of a large cohort of TAVI patients, elevated preprocedure PLR was not independently associated with MACE after TAVI. This is a novel finding in comparison with previous studies.

Abstract
Introduction Transcatheter aortic valve implantation (TAVI) although minimally invasive is still accompanied by changes in blood morphological parameters, some of them linked to unfavorable outcomes. Aim To find any association between changes in blood morphology reflecting an inflammatory response and acute kidney injury (AKI). Material and methods This study involved 176 consecutive transfemoral TAVI patients with a mean age of 78.4 ±7.0 years. Serum creatinine concentration (CREA) and blood morphology were analyzed in the blood samples taken before the procedure, then approximately 1, 24, 48 and 72 hours after the procedure, and lastly at the time of discharge. Post-procedural maximal or minimal values (max/min) and max/min-to-bs ratio of the laboratory parameters were also calculated. Results Leucocyte (WBC) and neutrophil (NEUT) counts increased significantly after the procedure whereas lymphocyte (LYMPH) counts declined markedly, reaching the highest or lowest values 24 hours after the procedure. A significant increase in neutrophil-to-lymphocyte ratio (NLR) was observed. Platelet count (PLT) dropped to a minimum at 72 hours after TAVI but at discharge did not return to the admission level. TAVI was associated with a marked increase in CREA with a peak at 48 hours after the procedure (135.7 ±75.9 μM/l). Patients with AKI (n = 65; 36.9%) presented more pronounced variations in relative changes in counts of all blood morphological parameters. A positive moderate (r = 0.412) correlation between maximal NLR and relative CREA changes was noted. Conclusions TAVI is associated with significant changes in blood morphological parameters that reflect an inflammatory response. They are more pronounced among subjects with post-procedural AKI.

Abstract
OBJECTIVES Fever following transcatheter aortic valve implantation (TAVI) is a common phenomenon, attributed mostly to inflammatory response which may impact outcome. Systemic inflammatory response may be triggered by multiple factors, most associated with the TAVI procedure itself. However, there are no data regarding the incidence of fever following TAVI in contemporary era with newer generation devices. Our primary objective was to measure temporal trends in fever incidence and features following TAVI. METHODS We analyzed a retrospective cohort of 802 consecutive patients who underwent TAVI at our institution between November 2008 and February 2018. We identified and characterized all patients who developed fever (>38.0°C from any cause) within the first 72 h following the procedure and analyzed incidence and characteristics stratified into 3 time frames: 2008-2014, 2014-2016, and 2016-2018. RESULTS Following TAVI, 190 (23.7%) patients developed fever (mean age 82.3 ± 5.2 years, 64.2% female). An infectious etiology was evident in only 32.1% of cases. The frequency decreased gradually and significantly across timeframes (32.8, 23.6, and 14.5%, respectively, p < 0.001). In a multivariate regression analysis, 1st generation CoreValve (HR 1.91; CI 95% 1.2-3.04, p = 0.006) was found to be associated with higher incidence of fever in addition to female gender, vascular complications, transfemoral access, and reduced GFR. CONCLUSIONS Fever incidence post TAVI decreased significantly throughout the last decade. The higher rate of fever in the early years of TAVI was likely associated with first-generation devices, vascular complications, and reduced GFR.

High-sensitivity C-reactive protein as a prognostic marker in patients undergoing valve surgery. POLISH JOURNAL OF THORACIC AND CARDIOVASCULAR SURGERY 2020; 17:15-19. [PMID: 32728357 PMCID: PMC7379212 DOI: 10.5114/kitp.2020.94185] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Subscribe] [Scholar Register] [Received: 11/14/2019] [Accepted: 02/23/2020] [Indexed: 11/17/2022]
Abstract
Introduction An inflammatory reaction is a local or systemic response of the organs or tissues of the body to many damaging factors. One of the exponents of the inflammatory process is C-reactive protein (CRP). Aim To investigate the prognostic value of C-reactive protein (CRP) in patients undergoing valve surgery. Material and methods A prospective study was conducted on a group of consecutive patients with haemodynamically significant valve defects who underwent elective valve repair or replacement surgery. The primary end-point was in-hospital death from all causes. Patients were followed by direct observation during hospitalization. The risk of surgery using Euro-SCORE II was calculated for each patient. The plasma levels of C-reactive protein were measured by the Cardiac C-Reactive Protein (Latex) High Sensitive Test (Roche, Germany). Results The study group included 562 patients. The mean age in the studied population was 63 (standard deviation (SD) ±12). The mean plasma preoperative CRP level was 0.39 ±0.3 mg/dl. The primary endpoint occurred in 25 patients. At multivariate analysis age (p = 0.01), CRP (p = 0.02) and NT-proBNP (p = 0.03) remained independent predictors of the primary endpoint. A significant correlation was found between the level of CRP and haemoglobin (r = -0.3; p < 0.0001), red cell distribution width (r = 0.22; p < 0.0001), ejection fraction (r = -0.24, p = 0.007), troponin T (r = 0.3; p < 0.0001), creatinine (r = 0.26; p = 0.001) and body mass index (r = -0.29; p = 0.005). The average total time of hospitalization after the operation in patients with occurrence of the primary endpoint was 25 ±13 days. Conclusions Elevated preoperative CRP was associated with a poorer outcome following valve surgery.

Abstract
Background This cohort study aims to retrospectively investigate the incidence of severe systemic inflammatory response syndrome (sSIRS) in patients following total aortic arch replacement (TAR) under deep hypothermic circulatory arrest (DHCA) with selective cerebral perfusion and its effect on clinical outcomes. Methods All patients who underwent TAR with DHCA were consecutively enrolled from January 2013 until December 2015 at our institute. sSIRS was diagnosed between 12 and 48 h postoperatively if patients met all four criteria of the SIRS definition. Results Of the 522 patients undergoing TAR with DHCA, 31.4% developed sSIRS. Patients aged under 60 yr were characterized by a higher prevalence of sSIRS (OR = 2.93; 95% CI 2.01–4.28; P <0.001). Higher baseline serum creatinine (OR = 1.61; 95% CI 1.18–2.20; P = 0.003), concomitant coronary disease (OR = 2.00; 95% CI 1.15–3.48; P = 0.015) and extended cardiopulmonary time (OR = 1.63; 95% CI 1.23–2.18; P = 0.001) independently contributed to a greater likelihood of postoperative sSIRS onset, while the preferred administration of ulinastatin (OR = 0.69; 95% CI 0.51–0.93; P = 0.015) and dexmedetomidine (OR = 0.36; 95% CI 0.23–0.56; P < 0.001) attenuated it. Patients with sSIRS had a greater risk of developing postoperative major adverse complications compared with the no sSIRS group [56.7%(93/164) vs 26.8% (96/358), P < 0.001]. sSIRS was found to be a significant risk factor for major adverse complications (OR, 4.52; 95% CI, 3.40–6.01; P < 0.001). A significant difference was revealed in in-hospital death following TAR between the sSIRS group and the no-sSIRS group [4.88% (8/164) vs 1.12% (4/358), P = 0.019]. The Kaplan-Meier curve indicated that the time to discharge from the intensive care unit was significantly prolonged in the sSIRS group compared with patients without it (log-rank p < 0.001). Conclusions sSIRS occurs commonly in patients following TAR with DHCA. There is an inverse association between age and sSIRS onset, whereby age over 60 yr can lower the risk of it. sSIRS development can increase the likelihood of major postoperative major adverse events.

Effect on Mortality of Systemic Thromboinflammatory Response After Transcatheter Aortic Valve Implantation. Am J Cardiol 2019; 124:1741-1747. [PMID: 31590911 DOI: 10.1016/j.amjcard.2019.08.036] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.2] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 07/30/2019] [Revised: 08/17/2019] [Accepted: 08/22/2019] [Indexed: 12/20/2022]
Abstract
After transcatheter aortic valve implantation (TAVI) there is consistently identified decrease in platelets accompanied by a leucocyte (white blood cell, WBC) increase. We aimed to analyze the prognostic value of early platelet and WBC count changes (thromboinflammatory response) after successful TAVI. Among 432 consecutive patients [median 83.0 years of age, 63.4% women], platelets and WBCs were measured before and for 7 days post-TAVI. Follow-up was 36.9 (21.4 to 48.0) months. Platelet decrease (∆%Platelet-max) and parallel WBC increase (∆%WBC-max) were seen at days 1 to 3. Both ∆%Platelet-max ≤-37.6% and ∆%WBC-max >72.5% predicted mortality (area under the curve = 0.569 and area under the curve = 0.626). The 30-day and 1-year mortality (13.1% and 26.2%) were highest among 28% patients with a greater decrease in platelets and a greater increase in WBCs; intermediate (0.9% and 12.3%) among 52.5% patients with either a greater decrease in platelets or a greater increase in WBCs, but not both; and lowest (0% and 6.6%) among 19.5% patients with a lesser decrease in platelets and a lesser increase in WBCs (p <0.001). Estimated 4-year mortality rates were 53.7% versus 36.2% versus 24.5%, respectively, p <0.001. Bleeding, surgical wounds, acute kidney, and brain injury predicted a more intense thromboinflammatory response, whereas use of the newer generations had the opposite effect. In conclusion, substantial thromboinflammatory response identified after successful TAVI predicts a higher long-term mortality.

Abstract
AIM The aim of the study was to investigate the prognostic value of selected biomarkers in patients undergoing valve surgery. MATERIALS & METHODS A prospective study was conducted on a group of consecutive patients with hemodynamically significant valve defects that underwent elective valve repair or replacement surgery. The primary end point was any major adverse event including death within 30 days. RESULTS The study group included 416 patients. The composite end point occurred in 81 patients. At multivariate analysis high-sensitivity C-reactive protein (p = 0.03), red cell distribution width (p = 0.0001) and red blood cell count (p = 0.005) remained independent predictors of the primary end point. CONCLUSION Elevated high-sensitivity C-reactive protein, red cell distribution width and red blood cell count were associated with a poorer outcome following valve surgery.

Abstract
Systemic inflammatory response syndrome (SIRS), initially reported after cardiovascular surgery, has been described after various interventional cardiology procedures, including endovascular/thoracic aortic repair (EVAR/TEVAR), implantation of heart rhythm devices, percutaneous coronary intervention (PCI), electrophysiology procedures (EP), and transcatheter aortic valve implantation (TAVI). In these settings, a comprehensive understanding of the triggers, pathogenesis as well as a common diagnostic/therapeutic algorithm is lacking and will be discussed in this review. SIRS occurs in about 40% and 50% of patients undergoing TEVAR/EVAR and TAVI respectively; it affects 0.1% of patients undergoing implantation of heart rhythm devices. Prevalence is unknown after PCI or EP. Clinical presentation includes fever, dyspnoea/tachypnoea, tachycardia, weakness, chest pain and pericardial/pleural effusion. Several triggers can be identified, related to implanted devices, biomaterial, and procedural aspects (prolonged hypotension, aneurysm thrombus manipulation, active fixation atrial leads, coronary microembolization, balloon dilatation/stent implantantation, contrast medium, coronary/myocardial microperforation). Nonetheless, these triggers share three main pathogenic pathways leading to SIRS clinical manifestations: leucocytes activation, endothelial injury/activation, and myocardial/pericardial injury. Therapy consists of non-steroidal agents, with corticosteroids as second-line treatment in non-responders. Although a benign evolution is reported after implantation of heart rhythm devices, PCI and EP, major adverse events may occur after EVAR/TEVAR and TAVI at short- and mid-term follow up.

Abstract
OBJECTIVES The inflammatory response to on-pump cardiac surgery is well known. Systemic inflammatory response syndrome after transcatheter valve implantation (TAVI) has been reported. The objective of this study was to study the inflammatory response during TAVI, and compare with the response during surgical aortic valve replacement. METHODS Eighteen patients undergoing transcatheter implantation, either by a transfemoral (n = 9) or transaortal (n = 9) approach were compared with eighteen patients admitted for surgical replacement. Blood samples per- and postoperatively were analysed for C3bc, terminal complement complex, myeloperoxidase, macrophage inflammatory protein-1β, monocyte chemo-attractant peptide-1, eotaxin, IL-6 and troponin-T. All markers were measured at defined time points and the areas under the curve were compared. RESULTS Activation of complement, granulocytes, monocytes and eosinophils were significantly lower in the transcatheter group as compared to the surgical group (<0.01). There was no difference in generation of troponin T and IL-6. A small difference in complement activation was observed between the transfemoral and transaortal placement of TAVI. There was no significant difference in clinical outcomes between the TAVI and surgical groups. DISCUSSION Activation and release of inflammatory markers was significantly less during with TAVI as compared to SAVR, particularly for markers associated with extracorporeal circulation. TAVI and SAVR generated the same degree of IL-6 and troponin T, indicating that the burden on the myocardial tissue was the same. Clinical Trials: Gov ID: NCT03074838 Unique protocol ID: 2012/7919.

Abstract
Symptomatic aortic stenosis can be treated by surgical aortic valve replacement (SAVR) or transcatheter aortic valve replacement (TAVR), the latter of which is regarded as a minimally invasive procedure. Differences between these procedures regarding immune responses or changes in coagulation and neurocognitive function have thus far been evaluated only sparsely. We carried out a prospective, single-center, nonrandomized explorative study with 38 patients. Thirteen patients were subjected to either SAVR or transfemoral (TF-) TAVR, and 12 patients underwent transapical (TA-) TAVR. Plasma cytokines (IL-6, -8, -18, presepsin) and acute-phase proteins (C-reactive protein, procalcitonin), markers of coagulation and platelet function, and neurocognitive function (via various standard tests) were assessed before and at five-time points during a 72-h follow-up after surgery. SAVR and TA-TAVR patients responded similarly to the procedure in terms of C-reactive protein, leukocyte numbers, and IL-6, whereas these responses were substantially lower in TF-TAVR patients. Only SAVR patients showed measurable IL-10 levels. SAVR patients without prior anticoagulation experienced a robust and transient restoration of platelet function after surgery, with no hypercoagulation observable in functional coagulation assays. None of the procedures led to an immediate improvement of hand and leg coordination, but patients after TA-TAVR had decreased neurocognitive function. Patients after SAVR or TA-TAVR exhibit a robust pro-inflammatory response, which is-on the cytokine level-counterbalanced only in SAVR patients. Our results point toward a greater impact of TA-TAVR on neurocognitive function and indicate a potentially detrimental activation of platelets in some patients after SAVR.

Abstract
OBJECTIVE To assess the association of systemic inflammation and outcome after major abdominal surgery. BACKGROUND Major abdominal surgery carries a high postoperative morbidity and mortality rate. Studies suggest that inflammation is associated with unfavorable outcome. METHODS Levels of C-reactive protein (CRP), interleukin-6 (IL-6), and tumor necrosis factor-α and the systemic inflammatory response syndrome (SIRS) were assessed in 137 patients undergoing major abdominal surgery. Blood samples were drawn on days 0, 1, 3, and 7, and SIRS was scored during 48 hours after surgery. Primary outcome was a composite of mortality, pneumonia, sepsis, anastomotic dehiscence, wound infection, noncardiac respiratory failure, atrial fibrillation, congestive heart failure, myocardial infarction, and reoperation within 30 days of surgery. RESULTS An IL-6 level more than 432 pg/mL on day 1 was associated with an increased risk of complications (adjusted odds ratio: 3.3; 95% confidence interval [CI]: 1.3-8.5) and a longer median length of hospital stay (7 vs 12 days, P < 0.001). As a single test, an IL-6 cut-off level of 432 pg/mL on day 1 yielded a specificity of 70% and a sensitivity of 64% for the prediction of complications (area under the curve: 0.67; 95% CI: 0.56-0.77). Levels of CRP started to discriminate from day 3 onward with a specificity of 87% and a sensitivity of 58% for a cut-off level of 203 mg/L (AUC: 0.73; 95% CI: 0.63-0.83). CONCLUSIONS A high IL-6 level on day 1 is associated with postoperative complications. Levels of IL-6 help distinguish between patients at low and high risk for complications before changes in levels of CRP.
