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.

Abstract
INTRODUCTION TAVI-related complications, such as conduction disturbances, vascular complications or death may be related to increased inflammatory response. The aim of this study was to elucidate the efficacy and safety of the systemic glucocorticoid therapy regarding the adverse events after TAVI deployment. EVIDENCE ACQUISITION We conducted a systemic search of PubMed, a reference list of relevant articles, and Medline. The main efficacy outcomes of interest were all-cause death, cardiac and non-cardiac death, permanent pacemaker implantation (PPM), new left bundle branch block (LBBB), stroke, and myocardial infarction (MI). Safety endpoints were major vascular complications, major bleeding events, and cardiac tamponade. EVIDENCE SYNTHESIS A total of 7 studies including data from 3439 patients with a median follow-up was 30 days. Systemic glucocorticoid compared to the control group were associated with an increased risk of non-cardiac death (Relative Risk [RR] 5.90 95%CI [2.95; 11.80], P<0.001) major vascular complications (RR 1.78, 95%CI [1.22 - 2.61], P=0.003) and cardiac tamponade (RR 3.42, 95%CI [1.69 - 6.92], P<0.001). However, there were no differences in all-cause death, cardiac death, new LBBB, stroke, MI, or major bleeding events (all P values >0.05). CONCLUSIONS Glucocorticoid therapy before the TAVI procedure was associated with an increase in non-cardiac death, major vascular events and cardiac tamponade. There were no differences in the risk of all-cause death, cardiac death, PPM or LBBB, stroke, or MI.

Abstract
Aortic valve stenosis is the most common type of heart valve disease in the United States and Europe and calcific aortic stenosis (AS) affects 2-7% of people aged 65 years and older. Aortic valve replacement (AVR) is the only effective treatment for individuals with this condition. Transcatheter Aortic Valve Replacement (TAVR) has been widely accepted as a minimally invasive therapeutic approach for addressing symptomatic AS in patients who are considered to have a high risk for traditional surgical intervention. TAVR procedure may have a paradoxical effect on the immune system and inflammatory status. A major portion of these immune responses is regulated by activating or inhibiting inflammatory monocytes and the complement system with subsequent changes in inflammatory cytokines. TAVR has the potential to induce various concurrent exposures, including disruption of the native valve, hemodynamic changes, antigenicity of the bioprosthesis, and vascular damage, which finally lead to the development of inflammation. On the other hand, it is important to acknowledge that TAVR may also have anti-inflammatory effects by helping in the resolution of stenosis.The inflammation and immune response following TAVR are complex processes that significantly impact procedural outcomes and patient well-being. Understanding the underlying mechanisms, identifying biomarkers of inflammation, and exploring therapeutic interventions to modulate these responses are crucial for optimizing TAVR outcomes. Further research is warranted to elucidate the precise immunological dynamics and develop tailored strategies to attenuate inflammation and enhance post-TAVR healing while minimizing complications.

Abstract
INTRODUCTION Systemic inflammatory response syndrome (SIRS) is related to increased circulating endothelial microparticles (EMP). OBJECTIVE The aim of this study was to compare the plasma concentration of EMP between patients undergoing aortic valve replacement with conventional bioprosthesis implantation and Perceval™ S (LivaNova) and to evaluate its impact on the inflammatory response in the short-term follow-up. METHODS This is a randomized clinical trial with 24 patients submitted to isolated aortic valve replacement divided into two groups: Perceval™ S (Group P) and conventional bioprostheses (Group C). Incidence of severe SIRS (three or more criteria) in the first 48 hours postoperatively, EMP release profile, interleukins (IL) 6 and 8, C-reactive protein, and procalcitonin were analyzed preand postoperatively at 24 hours and three months. RESULTS There were 24 patients (12 in each group), mean age was 69.92±5.17 years, 83.33% were female, the incidence of severe SIRS was 66.7% and 50% in groups C and P, respectively (P=0.68), and EMP showed a significant increase in the 24-hour postoperative period (P≤0.001) and subsequent decrease in the three-month postoperative period (P≤0.001), returning to baseline levels. For IL-6 and IL-8, there was a greater increase in group C at 24 hours postoperatively (P=.0.02 and P<0.001). CONCLUSION The incidence of severe SIRS was similar in both groups, with significantly higher levels of IL-6 and IL-8, at the 24-hour postoperative period, in group C, however with higher levels of EMP in group P, and subsequent return to baseline levels at the three-month postoperative period in both groups.

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
Neutrophils can release neutrophil extracellular traps (NETs) containing DNA fibres and antimicrobial peptides to immobilize invading pathogens. NET formation (NETosis) plays a vital role in inflammation and immune responses. In this study we investigated the impact of surgical trauma on NETosis of neutrophils. Nine patients undergoing "Transcatheter/percutaneous aortic valve implantation" (TAVI/PAVI, mild surgical trauma), and ten undergoing "Aortocoronary bypass" (ACB, severe surgical trauma) were included in our pilot study. Peripheral blood was collected before, end of, and after surgery (24 h and 48 h). Neutrophilic granulocytes were isolated and stimulated in vitro with Phorbol-12-myristate-13-acetate (PMA). NETosis rate was examined by microscopy. In addition, HLA-DR surface expression on circulating monocytes was analysed by flow-cytometry as a prognostic marker of the immune status. Both surgical procedures led to significant down regulation of monocytic HLA-DR surface expression, albeit more pronounced in ACB patients, and there was a similar trend in NETosis regulation over the surgical 24H course. Upon PMA stimulation, no significant difference in NETosis was observed over time in TAVI/PAVI group; however, a decreasing NETosis trend with a significant drop upon ACB surgery was evident. The reduced PMA-induced NETosis in ACB group suggests that the inducibility of neutrophils to form NETs following severe surgical trauma may be compromised. Moreover, the decreased monocytic HLA-DR expression suggests a post-operative immunosuppressed status in all patients, with a bigger impact by ACB, which might be attributed to the extracorporeal circulation or tissue damage occurring during surgery.

Abstract
Patients with a clinical indication for aortic valve replacement can either undergo surgical aortic valve replacement (SAVR) or Transcatheter Aortic Valve Implantation (TAVI). There are many different factors that go into determining which type of replacement to undergo, including age, life expectancy, comorbidities, frailty, and patient preference. While both options offer significant benefits to patients in terms of clinical outcomes and quality of life, there is growing interest in expanding the indications for TAVI due to its minimally invasive approach. However, it is worth noting that there are several discrepancies in TAVI outcomes in regards to various endpoints, including death, stroke, and major cardiovascular events. It is unclear why these discrepancies exist, but potential explanations include the diversity of etiologies for aortic stenosis, complex patient comorbidities, and ongoing advancements in both medical therapies and devices. Of these possibilities, we propose that phenotypic variation of aortic stenosis has the most significant impact on post-TAVI clinical outcomes. Such variability in phenotypes is often due to a complex interplay between underlying comorbidities and environmental and inherent patient risk factors. However, there is growing evidence to suggest that patient genetics may also play a role in aortic stenosis pathology. As such, we propose that the selection and management of TAVI patients should emphasize a precision medicine approach.

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.

Abstract
HLA‐DR isotype is a MHC‐II cell‐surface receptor found on APCs and plays a key role in initiating immune responses. In severely immunocompromised patients with conditions like sepsis, the number of HLA‐DR molecules expressed on leukocytes is considered to correlate with infectious complications and patients’ probability of survival. The underlying regulatory mechanisms of HLA‐DR expression remain largely unknown. One probable path to regulation is through microRNAs (miRNAs), which have been implicated as regulatory elements of both innate and adaptive immune system development and function. In our study, flow cytometry‐based high‐throughput miRNA screening was performed in a stable HLA‐DR‐expressing human melanoma cell line, MelJuSo, for either up‐ or downregulating miRNAs of the surface HLA‐DR expression. By the end of the screening, the top ten upregulators and top five downregulators were identified, and both the HLA‐DR protein and mRNA regulations were further verified and validated. In‐silico approaches were applied for functional miRNA‐mRNA interaction prediction. The potential underlying gene regulations of different miRNAs were proposed. Our results promote the study of miRNA‐mediated HLA‐DR regulation under both physiological and pathological conditions, and may pave the way for potential clinical applications.

Abstract
Objective Transcatheter aortic valve implantation (TAVI) provokes early injury response, represented in part by dynamic changes in the inflammatory markers. The association of self-expanding valves (SEVs) and balloon-expandable valves (BEVs) with the consequent inflammatory response remains uncertain. Materials and methods Patients with severe symptomatic aortic stenosis who underwent transfemoral TAVI: SEVs or BEVs, from January 2010 to December 2019 were enrolled. Whole white blood cells (WBC) and subpopulation dynamics as well the neutrophil to lymphocyte ratio (NLR) were evaluated. Results Three-hundred seventy consecutive patients (mean age 81.75 ± 6.8 years, 199 women’s) were enrolled. In the entire population, significant kinetic changes in the WBC response (p <0.0001) between admission and first 24 hours post procedure, with a significant increase in total WBC (7.46 ± 2.26 to 10.08 ± 3.55) and absolute neutrophil count (4.97 ± 2.06 to 8.19 ± 3.43), NL ratio (3.72 ± 2.8 to 9.76 ± 7.29), and a meaningful decrease in absolute lymphocytes count (1.67 ± 1.1 to 1.1 ± 0.76). When compared between the types of valves, SEVs were associated with a more pronounced inflammatory response than BEVs, with total WBC (10.44 ± 3.86 vs. 9.45 ± 3.19) neutrophils (8.56 ± 3.75 vs. 7.55 ± 3.06) with p 0.016 and 0.012 respectively. Conclusion This is the first description of a differential inflammatory response between the two leading delivery systems. SEV appears to trigger a more robust inflammatory response as compared to BEV. Clinical studies are warranted to assess the long term effect of our findings.

Abstract
Thrombocytopenia after TAVI is common and clinically detrimental. Retrospectively, we observed Portico recipients had a more profound platelet drop than Evolut recipients. We thus investigated periprocedural platelet damage and/orpro-inflammatory state in 64 TAVI recipients at baseline and after implantation. Platelet damage was assessed by annexin V staining and monocyte-phagocytic phenotype was assessed according to CD14/CD36 expression. Serum cytokines were measured in 20 patients. The formaldehyde-based storage solution altered platelets. When, before being loaded onto the delivery system, Portico underwent one additional flushing to those recommended, the receiving patients showed thrombocytopenia, platelet damage, and CD36-monocyte count were mitigated. A general increase in IL-6 was recorded in overall TAVI recipients, but a high serum level of IL-8, a potent thrombocytopenia inducer, was measured in Portico recipients only, including those with extra-rinsed valve. Our study suggests a platelet-injury effect by storage-solution and generates the hypothesis of a role for the biomaterial in stimulating innate-immunity. Larger prospective studies are needed.

Abstract
INTRODUCTION The development of biomarkers to guide management of anti-tumor necrosis factor (TNF) agents in patients with inflammatory bowel disease (IBD) is an unmet need. We developed an in vitro blood assay to predict patient long-term outcome with the anti-TNFα agent infliximab (IFX). METHODS Patients with IBD were classified according to the shedding of an L-selectin (CD62L) from the surface of their granulocytes in whole blood. CD62L shedding was quantified by flow cytometry before and after drug administration. A clinical data collection from June 2012 to August 2017 with blinded IFX management was aimed at validating the long-term predictive value of this test. RESULTS Among 33 patients with IBD (17 Crohn's disease and 5 ulcerative colitis), 22 were predicted functional responders (PFR) and 11 were predicted as nonresponders (NR) according to the in vitro test. Five years after study initiation, 72% of PFR were still treated with IFX (vs 27% in the NR group; P < 0.05), with a median time spent under IFX of 45 vs 12 months (P = 0.019), respectively. Thirty-five medicosurgical events occurred with a median time to first event of 3 vs 30 months (P = 0.023), respectively. Our assay was the best independent predictor of staying long term on IFX (P = 0.056). DISCUSSION An assay-based in vitro test for functional blockade of TNFα (CD62L shedding) provides an excellent long-term (at 3-5 years) independent predictor of durable use of IFX in patients with IBD. Testing patients could personalize decision making to significantly reduce costs and risk of adverse events and complications.

Transcatheter aortic valve replacements alter circulating serum factors to mediate myofibroblast deactivation. Sci Transl Med 2020; 11:11/509/eaav3233.

Abstract
The transcatheter aortic valve replacement (TAVR) procedure has emerged as a minimally invasive treatment for patients with aortic valve stenosis (AVS). However, alterations in serum factor composition and biological activity after TAVR remain unknown. Here, we quantified the systemic inflammatory effects of the TAVR procedure and hypothesized that alterations in serum factor composition would modulate valve and cardiac fibrosis. Serum samples were obtained from patients with AVS immediately before their TAVR procedure (pre-TAVR) and about 1 month afterward (post-TAVR). Aptamer-based proteomic profiling revealed alterations in post-TAVR serum composition, and ontological analysis identified inflammatory macrophage factors implicated in myofibroblast activation and deactivation. Hydrogel biomaterials used as valve matrix mimics demonstrated that post-TAVR serum reduced myofibroblast activation of valvular interstitial cells relative to pre-TAVR serum from the same patient. Transcriptomics and curated network analysis revealed a shift in myofibroblast phenotype from pre-TAVR to post-TAVR and identified p38 MAPK signaling as one pathway involved in pre-TAVR–mediated myofibroblast activation. Post-TAVR serum deactivated valve and cardiac myofibroblasts initially exposed to pre-TAVR serum to a quiescent fibroblast phenotype. Our in vitro deactivation data correlated with patient disease severity measured via echocardiography and multimorbidity scores, and correlations were dependent on hydrogel stiffness. Sex differences in cellular responses to male and female sera were also observed and may corroborate clinical observations regarding sex-specific TAVR outcomes. Together, alterations in serum composition after TAVR may lead to an antifibrotic fibroblast phenotype, which suggests earlier interventions may be beneficial for patients with advanced AVS to prevent further disease progression. Transcatheter aortic valve replacement alters a patient’s serum proteome, reversing valvular interstitial cell and cardiac myofibroblast activation. Aortic valve stenosis (narrowing of the aortic valve) contributes to inadequate blood flow, fibrosis, hypertrophy, and, ultimately, heart failure. Transcatheter aortic valve replacement (TAVR) improves blood flow, but little is known about cardiac remodeling after the procedure. Aguado and colleagues performed proteomics on serum samples collected from patients before and after TAVR and studied the effects of serum on valve and cardiac cells using hydrogel culture platforms. A role for p38 MAPK signaling in activating cells was identified using pre-TAVR serum, whereas post-TAVR serum returned cells to a quiescent state. Along with preliminary insights into sex-specific differences, the authors’ research supports a role for TAVR-induced alteration of circulating inflammatory cytokines in regulating valve cell phenotype.

Effect of Transcatheter Aortic Valve Implantation on the Immune Response Associated With Surgical Aortic Valve Replacement. Am J Cardiol 2020; 128:35-44.

Abstract
The immune response after transcatheter aortic valve implantation (TAVI) in comparison to that after surgical aortic valve replacement (SAVR) remains to be fully elucidated. In a 2-part study, we assessed laboratory data obtained before, immediately after, and 24 and 48 hours after SAVR (128 patients; age ≥80 [mean 82] years) or transfemoral TAVI (102 patients; age ≥80 [mean 86] years) performed for aortic stenosis. In-hospital mortalities were similar (3% vs 0%), but leukocyte counts and aspartate aminotransferase and creatine kinas concentrations were decreased immediately and 24 hours after surgery (all, p <0.001). We performed cytokine profiling in a SAVR group (11 patients; mean age, 77 years) and transfemoral TAVI group (12 patients; mean age, 84 years). By measuring normalized concentrations of 71 cytokines at 3 time points, we found a significant difference (defined as fold change >1.7 and p <0.05 [by Mann-Whitney U-test]) in 23 cytokines. The differentially expressed cytokines fell into 3 hierarchical clusters: cluster A (high increase after SAVR and suppressed increase after TAVI only immediately after surgery [CCL2, CCL4, and 2 others]), cluster B (high increase after SAVR and suppressed increase after TAVI at 2 time points [IL-1Ra, IL-6, IL-8, IL-10, and 5 others]), and cluster C (various patterns [TRAIL, CCL11, and 8 others]). Gene enrichment analysis identified multiple pathways associated with the inflammatory responses in SAVR and altered responses in TAVI, including cellular responses to tumor necrosis factor (p = 0.0035) and interleukin-1 (p = 0.0062). In conclusion, a robust inflammatory response follows SAVR, and a comparatively attenuated response follows TAVI.

Abstract
Atrial Fibrillation (AF) is very common among patients with severe aortic stenosis. Moreover, new onset AF (NOAF) is a frequent finding after Transcatheter Aortic Valve Replacement (TAVR). There is a significant impact of AF on outcomes in patients undergoing TAVR including mortality, thrombo-embolic and bleeding events. There is lack of clear evidence about the optimal management of AF in TAVR patients. This review aims to summarize the epidemiology, predictors, prognosis, therapeutic considerations and challenges in the management of AF in patients undergoing TAVR.

Abstract
Aortic valve stenosis is one of the most common valvular heart disorders and the prevalence will rise as the population ages. Once symptomatic patients with aortic valve stenosis tend to fare worse with high mortality rates. Aortic valve replacement is indicated in these patients and besides the standard surgical replacement, a less invasive approach, transcatheter aortic valve implantation, has gained momentum and has showed promising and solid results in patients with high surgical risk. An important aspect of evaluating patients with aortic valve stenosis is the ability to choose the best possible candidate for the procedure. In addition, predicting the short and long-term clinical outcomes after the valve replacement could offer the treating physicians a better insight and provide information for optimal therapy. Biomarkers are biological parameters that can be objectively measured and evaluated as indicators of normal biological processes and are easily monitored. The aim of this review is to critically assess some of the most widely used biomarkers at present (natriuretic peptides, troponins, C-reactive protein) and provide an insight in novel biomarkers that are currently being investigated (galectin-3, growth differentiation factor-15, microRNAs) for possible diagnostic and prognostic use in aortic valve stenosis and transcatheter aortic valve implantation respectively.

Abstract
Background Transcatheter aortic valve implantation (TAVI) is the standard therapy for high-risk patients with aortic stenosis (AS). TAVI-outcomes are widely investigated in comparison to surgical aortic valve replacement (SAVR), but less is known about infectious complications after TAVI. We aimed to compare early and mid-term infectious outcomes of patients undergoing TAVI or SAVR. Methods The present study is a prospective single-centre study including 200 consecutive patients between 06/2014-03/2015 undergoing TAVI (either transfemoral or transapical and transaortic, n=47+53=100) or SAVR (either isolated or concomitant with CABG, n=52+48=100). The mean age and log. EuroSCORE were significantly different between both groups (81±6 versus 69±11 years, P<0.001 and 23.1%±13.8% versus 8.7%±9.5%, P<0.001). Primary endpoints included wound healing disorders, respiratory and urinary tract infections and incidence of endocarditis or sepsis within hospital stay. Secondary endpoints included infectious parameters, infectious related rehospitalisation and 2-year mortality. Results Primary endpoints showed no difference in overall TAVI- versus SAVR-groups regarding respiratory- (14% versus 19%, P=0.45), urinary-tract (7% versus 4%, P=0.54) infections, sepsis (5% versus 6%, P=1.0), endocarditis (0% versus 1%, P=1.0) or 30-day mortality (10% versus 4%, P=0.09), except for wound disorders, which were significantly lower in the TAVI-group (1% versus 8%, P=0.035), respectively. Secondary endpoints reported no difference regarding infectious related rehospitalisation (4% versus 4%, P=1.0), but significantly higher 2-year mortality (28% versus 16%, P=0.048) in the TAVI-group. Conclusions So far, little has been studied about infectious complications after TAVI. This study reports no difference between the overall TAVI and SAVR groups regarding infectious complications. However, SAVR group show more wound healing disorders but less mortality than TAVI group.

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
Atrial fibrillation (AF) is a common arrhythmia in patients with aortic stenosis. When these patients are treated medically or by surgical aortic valve replacement, AF is associated with increased risk of adverse events including death. Growing evidence suggests a significant impact of AF on outcomes also in patients with aortic valve stenosis undergoing transcatheter aortic valve implantation (TAVI). Conversely, limited evidence is available regarding the optimal management of this condition. This review aims to summarize prevalence, pathophysiology, prognosis, and treatment of AF in patients undergoing TAVI.

Abstract
Extracorporeal circulation triggers systemic inflammatory response and coagulation disorders which may lead to unfavorable clinical outcome. A type II minimally-invasive extracorporeal circuit (MiECC) is a closed system with markedly reduced artificial surface as compared to conventional extracorporeal circuits (CECC). The aim of this study was to investigate and compare inflammatory responses, complement activation and selected clinical end-points in isolated surgical aortic valve replacement (SAVR) performed with a type II MiECC circuit or a CECC. Fifty patients were prospectively randomized to MiECC or CECC perfusion regimen. Complement activation (sC5b-9), inflammation (IL-6, TNF-α, sCD40-ligand) and activation of the coagulation system (D-dimer, TAT-complex) were determined before operation, at 2 hours and 24 hours after surgery. Clinical end-points included perfusion time, transfusion of allogeneic blood products, postoperative bleeding, sepsis, new onset of atrial fibrillation, stroke and in-hospital mortality. Patient characteristics and baseline plasma markers were similar in both groups. Levels for sC5b-9, TNF-α, sCD40 ligand, TAT-complex and D-dimers were not significantly different between MiECC and CECC at 2 hours and 24 hours after surgery. The IL-6 plasma concentration was lower in the CECC group at 24 hours (P = 0.026, vs. MiECC). Comparisons of the baseline level to values at 2 hours and 24 hours, adjusted for the type of oxygenator and hemoglobin, showed a significantly lower sC5b-9 in MiECC at 2 hours (P = 0.013), but no difference at 24 hours (P=0.990). Compared with CECC, MiECC patients had a shorter perfusion time (P = 0.037) and less transfusion requirements (P = 0.04). In this selected cohort of SAVR patients, the type II MiECC was not inferior to CECC in terms of inflammatory response and complement activation. Thus, MiECC might be an alternative perfusion strategy to conventional.

Abstract
Background The inflammatory process in aortic valvular stenosis persists after surgery to replace the valve in almost half of the patients. No association has been found to its persistence. The main objective of this study was to evaluate the inflammatory response in patients with aortic stenosis through the determination of several biomarkers in plasma measured before and after the valvular replacement and to seek an association with the type of prosthesis used. Methods This is an observational study with a follow up of 6 months in subjects with severe aortic stenosis. Seric concentrations of TNFa, IL-1, IL-6 and ICAM and echocardiographic variables were quantified previous to the surgery and a week and 6 months after it. A group of control subjects paired by age and gender was included. Results Seventy-nine subjects were studied of which 57% were male; the average age was of 59 (± 11.4) years. Previous to surgery, the concentration of cytokines was higher in patients than in control subjects. A biological prosthesis was implanted in 48 patients and a mechanical prosthesis in 31. Both, types of prosthesis have components made of titanium. The echocardiograms 1 week and 6 months after the surgery showed a decrease in the mean aortic gradient and an increase in the valvular area (p = 0.001). Half of the patients still showed high proinflammatory cytokine levels. There were no differences according to the type of prosthesis implanted after adjustments for demographic variables, comorbidities and echocardiographic data. Conclusions The inflammatory response caused by both types of valvular prothesis at 6 months after implantation were similar. Both types of prosthesis are recommended, they had similarities in hemodynamic profiles registered with Doppler echocardiography. Age of the patient or the suitability use of anticoagulants determines the type of prosthesis to be used.

Impact of clinical and procedural factors upon C reactive protein dynamics following transcatheter aortic valve implantation. World J Cardiol 2016; 8:425-431. [PMID: 27468335 PMCID: PMC4958693 DOI: 10.4330/wjc.v8.i7.425] [Citation(s) in RCA: 6] [Impact Index Per Article: 0.8] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 03/24/2016] [Revised: 04/24/2016] [Accepted: 05/27/2016] [Indexed: 02/06/2023] Open
Abstract
AIM: To determine the effect of procedural and clinical factors upon C reactive protein (CRP) dynamics following transcatheter aortic valve implantation (TAVI).
METHODS: Two hundred and eight consecutive patients that underwent transfemoral TAVI at two hospitals (Imperial, College Healthcare NHS Trust, Hammersmith Hospital, London, United Kingdom and San Raffaele Scientific Institute, Milan, Italy) were included. Daily venous plasma CRP levels were measured for up to 7 d following the procedure (or up to discharge). Procedural factors and 30-d safety outcomes according to the Valve Academic Research Consortium 2 definition were collected.
RESULTS: Following TAVI, CRP significantly increased reaching a peak on day 3 of 87.6 ± 5.5 mg/dL, P < 0.001. Patients who developed clinical signs and symptoms of sepsis had significantly increased levels of CRP (P < 0.001). The presence of diabetes mellitus was associated with a significantly higher peak CRP level at day 3 (78.4 ± 3.2 vs 92.2 ± 4.4, P < 0.001). There was no difference in peak CRP release following balloon-expandable or self-expandable TAVI implantation (94.8 ± 9.1 vs 81.9 ± 6.9, P = 0.34) or if post-dilatation was required (86.9 ± 6.3 vs 96.6 ± 5.3, P = 0.42), however, when pre-TAVI balloon aortic valvuloplasty was performed this resulted in a significant increase in the peak CRP (110.1 ± 8.9 vs 51.6 ± 3.7, P < 0.001). The development of a major vascular complication did result in a significantly increased maximal CRP release (153.7 ± 11.9 vs 83.3 ± 7.4, P = 0.02) and there was a trend toward a higher peak CRP following major/life-threatening bleeding (113.2 ± 9.3 vs 82.7 ± 7.5, P = 0.12) although this did not reach statistical significance. CRP was not found to be a predictor of 30-d mortality on univariate analysis.
CONCLUSION: Careful attention should be paid to baseline clinical characteristics and procedural factors when interpreting CRP following TAVI to determine their future management.
