Abstract Funding Acknowledgements Type of funding sources: None. Background-Transcatheter aortic valve replacement (TAVR) is associated with periprocedural bleeding , mainly driven by vascular complications leading to blood cell transfusion. Additionally, anemia is highly prevalent in this population. The decision regarding the necessity for blood transfusion in patients undergoing TAVR is challenging. Methods-Electronic databases (Medline, Embase, Scopus, Cochrane) were searched from inception to December 16th, 2020. Unadjusted odds ratios (OR) were calculated from dichotomous data using Mantel Haenszel (M-H) random-effects with statistical significance to be considered if the confidence interval excludes 1 and p < 0.05.The primary outcomes of interest were all-cause mortality, myocardial infarction(MI), Stroke(CVA), and acute kidney injury(AKI). Results- A total of six studies with 6701 participants (Transfusions = 1505, Non-Transfusions = 5196) were included in our analysis. Average follow-up duration was 30 days. Mean age was 82.4 and 81.5 in the Transfusions and Non-transfusions group respectively. RBC transfusion was associated with higher 30-day mortality (OR-4.08; 95%CI 2.29-7.27; p < 0.00001; I2 = 77) as well as increased risk of acute kidney injury (AKI) (OR 2.97;95%CI 2.07-4.26; p < 0.00001; I2 = 77) and stroke (OR 2.44; 95%CI 1.78- 3.34; p < 0.00001,I2 = 0) However, there was no significant difference in the incidence of MI (OR 1.15;95%CI 0.50-2.64; p = 0.74,I2 = 0) Conclusion- RBC transfusion is a correlate and an independent predictor of all-cause mortality, acute kidney injury and stroke in this patient population and should be used with caution Abstract Figure.

Recent studies have suggested that contrast medium (CM) volume is associated with acute kidney injury (AKI) after transcatheter aortic valve replacement (TAVR). However, in a high-risk elderly TAVR population, the prognostic value and ideal threshold of CM dosage for AKI is unclear. Data of 532 successive TAVR patients (age 81.1 ± 6.8 years, EuroSCORE II 4.8% ± 6.0%) were therefore retrospectively analyzed. Based on a recently published formula, the renal function (preprocedural serum creatinine: SCr) corrected ratio of CM and body weight (CM*SCr/BW) was calculated to determine the risk of postprocedural contrast-associated AKI. AKI occurred in 94 patients (18.3%) and significantly increased 1-year all-cause mortality (23.4% vs. 13.1%; p = 0.001). A significant correlation between AKI and 30-day as well as 1-year all-cause mortality was observed (p = 0.001; p = 0.007). However, no association between CM dosage or the CM*SCr/BW ratio with the occurrence of AKI was seen (p = 0.968; p = 0.442). In our all-comers, all-access cohort, we found no relationship between CM dosage, or the established risk ratio model and the occurrence of postprocedural AKI. Further research needs to be directed towards different pathophysiological causes and preventive measures as AKI impairs short- and long-term survival.

Background: There is no consensus on the benefit of red blood cell (RBC) transfusion after transcatheter aortic valve replacement. Methods: The multicenter Transfusion Requirements in Transcatheter Aortic Valve Implantation (TRITAVI) registry retrospectively included patients after transfemoral transcatheter aortic valve replacement; propensity score-matching identified pairs of patients with and without RBC transfusion. The primary end point was 30-day mortality; nonfatal myocardial infarction, cerebrovascular accident, and stage 2 to 3 acute kidney injury at 30 days were secondary end points. We repeated propensity score-matching according to the hemoglobin nadir, hemoglobin drop, and in the subgroup of uncomplicated patients, without major vascular complications or major bleeding. Results: Among 2587 patients, RBC transfusion was administered in 421 cases (16%). The primary end point occurred in 104 (4.0%) patients, myocardial infarction in 9 (0.4%), cerebrovascular accident in 38 (1.5%), and acute kidney injury in 125 (4.8%) cases. In the 842 propensity-matched patients, RBC transfusion was associated with increased mortality (hazard ratio, 2.07 [95% CI, 1.06–4.05]; P =0.034) and acute kidney injury (hazard ratio, 4.35 [95% CI, 2.21–8.55]; P <0.001). Interaction testing between RBC transfusion and mortality was not statistically significant in the above-mentioned subgroups, and such association was not documented in the corresponding propensity score-matched cohorts. In the multivariable Cox proportional hazards regression model, major vascular complications ( P =0.044), major bleeding ( P =0.041), and RBC transfusion ( P =0.048) were independent correlates of 30-day mortality. Conclusions: RBC transfusion correlates with increased mortality and acute kidney injury early after transcatheter aortic valve replacement and is an independent predictor of 30-day mortality, irrespective of periprocedural major bleeding and vascular complications.

Background: The objective of this meta-analysis was to evaluate the risk of acute kidney injury (AKI) in patients who underwent transcatheter aortic valve replacement (TAVR). Methods: A literature search was performed using MEDLINE, EMBASE, the Cochrane Database of Systematic Reviews and clinicaltrials.gov from inception through October, 2014. Studies that reported relative risks, ORs, or hazard ratios comparing the AKI risk in patients who underwent TAVR versus those who underwent surgical aortic valve replacement were included. We performed the pre-specified sensitivity analysis including only propensity score-based studies. Mortality risk was evaluated among the studies that reported AKI outcome. Pooled risk ratios (RRs) and 95% confidence interval (CI) were calculated using a random-effect, generic inverse variance method. Results: Three randomized controlled trials (RCTs) with 1,852 patients and 14 cohort studies with 3,113 patients were analyzed to assess the AKI risk in patients undergoing TAVR. The pooled RRs of AKI in patients undergoing TAVR were 0.65 (95% CI 0.36-1.15, I2 = 75%) in the analysis of RCTs and propensity score-based studies and 0.76 (95% CI 0.44-1.34, I2 = 79%) in the analysis of observational studies. Sensitivity analysis in RCTs and propensity score-based studies using a standard AKI definition demonstrated a significant association between TAVR and lower AKI risk (RR 0.35, 95% CI 0.25-0.50, I2 = 0%). Our meta-analyses of RCTs and propensity score-based studies did not find associations between TAVR and reduced risks of severe AKI requiring dialysis (RR 0.82, 95% CI 0.38-1.79, I2 = 63%). Conclusions: Our meta-analysis demonstrates an association between TAVR and lower AKI risk.
