Abstract Background: Galectin-3 may predict mortality for patients with aortic stenosis (AS) after transcatheter aortic valve replacement (TAVR). However, the results were inconsistent. We aimed to evaluate the association between baseline galectin and mortality after TAVR in a meta-analysis. Methods: Related follow-up studies were obtained by systematic search of PubMed, Cochrane’s Library, and Embase databases. Both the fixed- and the random-effect models were used for the meta-analysis. Subgroup analyses were performed to evaluate the influences of study characteristics on the outcome. Results: Five prospective cohort studies with 854 patients were included, with a follow-up period between 1 and 1.9 years. Patients with higher baseline circulating galectin-3 had an increased risk of all-cause mortality after TAVR (random-effects model: risk ratio [RR]: 1.63, 95% confidence interval [CI]: 1.19–2.23, P=0.002; fixed-effects model: RR: 1.62, 95% CI: 1.19–2.20, P=0.002; I2 = 4%). Adjustment of estimated glomerular filtration rate (RR: 1.73, P=0.02) or B-type natriuretic peptide (BNP) or N-terminal pro-BNP (RR: 1.83, P=0.02) did not significantly affect the result. A trend of stronger association between higher baseline circulating galectin-3 and increased risk of all-cause mortality after TAVR was observed in studies with an enzyme-linked fluorescent assay (ELFA) (RR: 3.04, P=0.003) compared with those with an enzyme-linked immunosorbent assay (ELISA) (RR: 1.42, P=0.04; P for subgroup difference =0.06). Conclusion: Higher circulating galectin-3 before the procedure may predict all-cause mortality of AS patients after TAVR.

Background: Although current guidelines recommend dual antiplatelet therapy (DAPT) for 3 to 6 months following transcatheter aortic valve replacement (TAVR), there are no studies directly comparing outcomes of different durations of DAPT following TAVR. Methods: Pubmed and EMBASE were searched through May, 2020 to identify clinical studies that investigated single antiplatelet therapy (SAPT) versus DAPT use following TAVR. Studies using oral anticoagulants and antiplatelet therapy concomitantly were excluded. The DAPT group was subdivided by the duration of DAPT. We extracted the risk ratios (RRs) of major or life-threatening bleeding, stroke, and all-cause mortality. Results: Three randomized controlled trials, two propensity-score matched studies, and one observational study were identified, yielding a total of 1,833 patients who underwent TAVR assigned to the SAPT group (n=918), 3-month DAPT group (n=151), or 6-month DAPT group (N=764). Pooled analyses demonstrated that the rates of major or life-threatening bleeding were significantly higher in the 6-month DAPT group compared with the SAPT group (RR [95% CI] =2.54 [1.49-4.33], P =0.007) while no such difference was observed between the SAPT vs. 3-month DAPT groups or the 3-month DAPT vs. 6-month DAPT groups (Figure). P-scores were 98.1% (SAPT), 32.3% (3-month DAPT), and 19.6% (6-month DAPT). The rates of stroke and all-cause mortality were similar among the groups. Conclusions: In our network meta-analysis, we observed that DAPT for 6 months following TAVR was associated with increased risk of bleeding without decreasing the risk of stroke compared with SAPT, while there was no difference between DAPT for 3 months and 6 months.

Background Although current guidelines recommend dual antiplatelet therapy (DAPT) for 3 to 6 months following transcatheter aortic valve replacement (TAVR), there are no studies directly comparing outcomes of different durations of DAPT following TAVR. Methods and Results PubMed, EMBASE, and Cochrane Database were searched through November 2020 to identify clinical studies that investigated single antiplatelet therapy versus DAPT use following TAVR. Studies using oral anticoagulants and antiplatelet therapy concomitantly were excluded. The DAPT group was subdivided by the duration of DAPT. We extracted the risk ratios (RRs) of major or life‐threatening bleeding, stroke, and all‐cause mortality. Four randomized controlled trials, 2 propensity‐score matched studies, and 1 observational study were identified, yielding a total of 2498 patients who underwent TAVR assigned to the single antiplatelet therapy group (n=1249), 3‐month DAPT group (n=485), or 6‐month DAPT group (n=764). Pooled analyses demonstrated that when compared with the single antiplatelet therapy group, the rates of major or life‐threatening bleeding were significantly higher in the 3‐ and 6‐month DAPT groups (RR [95% CI]=2.13 [1.33–3.40], P =0.016; RR [95% CI]=2.54 [1.49–4.33], P =0.007, respectively) with no difference between the 3‐month DAPT versus 6‐month DAPT groups. The rates of stroke and all‐cause mortality were similar among the 3 groups. Conclusions In this network meta‐analysis of antiplatelet therapy following TAVR, single antiplatelet therapy with aspirin had lower bleeding without increasing stroke or death when compared with either 3‐ or 6‐month DAPT.

Abstract OBJECTIVES We sought to determine the optimal antithrombotic therapy after transcatheter aortic valve replacement. METHODS Related scientific databases were searched until December 2018. We conducted a pairwise and a network meta-analysis within a frequentist framework, measuring 30-day bleeding, stroke and all-cause mortality. The surface under the cumulative ranking (SUCRA) curve was estimated to rank the therapies. The Grading of Recommendations Assessment, Development and Evaluation (GRADE) approach was performed. The protocol was registered with PROSPERO (CRD42018111163). RESULTS Eight studies comprising 2173 patients were analysed. The risk of 30-day bleeding was higher for dual antiplatelet therapy (DAPT) than single antiplatelet therapy (SAPT) [odds ratio (OR) 1.90 (1.10–3.28); P = 0.02], whereas there was no difference in the risk of 30-day stroke [OR 1.27 (0.38–4.20); P = 0.69] and mortality [OR 1.46 (0.67–3.22); P = 0.34] between DAPT and SAPT. In the network meta-analysis, DAPT + oral anticoagulant (OAC) increased the risk of 30-day bleeding compared with SAPT [OR 6.21 (1.74–22.17); P = 0.005], DAPT [OR 3.27 (1.04–10.32); P = 0.043], SAPT + OAC [OR 4.87 (2.51–9.45); P < 0.001] and OAC [OR 14.4 (1.3–154.7); P = 0.028]. Additionally, patients receiving DAPT + OAC had the highest risks for 30-day bleeding (SUCRA 1.0%). OAC seemed to be superior to SAPT and DAPT in terms of 30-day bleeding (SUCRA OAC: 86.3%, SAPT: 72.3%, DAPT: 32.3%) and stroke (SUCRA 54.2%, 47.4%, 40.5%), but not mortality (SUCRA 69.6%, 74.1%, 43.4%). CONCLUSIONS There is a trend towards less bleeding with the application of SAPT, but no mortality benefit with the application of DAPT is shown. The comparison of SAPT, DAPT and OAC shows that OAC may improve the balance between stroke and bleeding, which can reduce the risk of mortality. In addition, the application of DAPT + OAC was ranked the worst amongst all treatment modalities and should be avoided due to an increased risk of bleeding.

Abstract Introduction Few data exist regarding the late clinical impact of the Selvester score prediction of myocardial fibrosis after transcatheter aortic valve replacement (TAVR). This study evaluated the predictive power of the Selvester score on survival in patients with aortic stenosis (AS) undergoing TAVR. Methods and results Patients with severe AS who had preoperative electrocardiograms were included. Clinical follow-up was obtained retrospectively. The primary endpoint was all-cause mortality. Secondary endpoints were cardiovascular death and major adverse cardiac events (MACE). Two hundred twenty-eight patients were included (mean age, 81.5±7.4 years; women, 58.3%). Deceased patients had a higher mean score (4.6±3.2 vs. 1.4±1.3; p<0.001). At a mean follow-up of 36.2±21.2 months, the Selvester score was independently associated with all-cause mortality (hazard ratio [HR], 1.65; 95% confidence interval [CI], 1.48–1.84; p<0.001), cardiovascular death (HR, 1.59; 95% CI, 1.38–1.74; p<0.001), and MACE (HR, 1.55; 95% CI, 1.30–1.68; p<0.001). After 5 years, the mortality risk was incrementally related to the Selvester score. The involvement of the inferior wall of the left ventricle was a lower mortality risk (HR, 0.42; 95% CI, 0.18 to 0.98; p=0.046). For a Selvester score of 3, the area under the curve showed 0.92, 0.94, and 0.86 (p<0.001), respectively, for 1, 2, and 3 years. Conclusions Elevated Selvester scores increase the risk of poor outcomes in patients with AS undergoing TAVR. The involvement of the anterior or lateral wall presents worse prognosis.

Background: The transfemoral (TF) route is the gold-standard access for transcatheter aortic valve replacement (TAVR). In 10–15% of patients, alternative accesses are needed, such as the transcarotid (TC) access. We performed a meta-analysis to compare 30-day mortality and complications between TC-TAVR and TF-TAVR.Methods: We searched PubMed/MEDLINE and EMBASE from inception to January 2021 to identify articles comparing TC-TAVR and TF-TAVR. Patients' baseline characteristics, procedural outcomes, and clinical 30-day outcomes were extracted.Results: We identified 9 studies, among which 2 used propensity-score matching, including 1,374 TC patients and 3,706 TF patients. TC-TAVR was associated with significantly higher EuroSCORE II and Logistic EuroSCORE values (respectively 8.0 ± 6.7 vs. 6.3 ± 5.4, p = 0.002 and 20.8 ± 14.2% vs. 20.0 ± 13.4%, p = 0.04), a higher prevalence of peripheral artery disease (52.6 vs. 32.8%, p = 0.001), previous cardiac surgery (26.3 vs. 22.4%, p = 0.008) and coronary artery disease (64.6 vs. 60.5%, p = 0.020). The pooled results found TC-TAVR to be associated with a significantly higher 30-day mortality risk (RR, 1.41, 95% CI, 1.02–1.96, p = 0.040), and a lower rate of 30-day major vascular complications (RR, 0.48, 95% CI, 0.25–0.92, p = 0.030). No significant difference was found regarding permanent pacemaker implantation, major bleeding and acute kidney injury. A subgroup analysis of the two propensity-score matched studies found a statistically increased risk of 30-day neurovascular complications (RR, 1.61, 95% CI, 1.02–2.55, p = 0.040).Conclusion: Compared with TF-TAVR, TC-TAVR was associated with an increased risk of 30-day mortality, likely related to a higher surgical risk and comorbidity burden, and with an increased risk of 30-day neurovascular complications. Careful preprocedural patient selection and close periprocedural neurological monitoring are paramount.

ObjectiveTo evaluate the changes in transvalvular gradients and the incidence of valve haemodynamic deterioration (VHD) following transcatheter aortic valve replacement (TAVR), according to use of anticoagulation therapy.Methods and resultsThis multicentre study included 2466 patients (46% men; mean age 81±7 years) who underwent TAVR with echocardiography performed at 12-month follow-up. Anticoagulation therapy was used in 707 patients (28.7%) following TAVR (AC group). A total of 663 patients received vitamin K antagonists, and 44 patients received direct oral anticoagulants. A propensity score matching analysis was performed to adjust for intergroup (AC vs non-AC post-TAVR) differences. A total of 622 patients per group were included in the propensity-matched analysis. VHD was defined as a ≥10 mm Hg increase in the mean transprosthetic gradient at follow-up (vs hospital discharge). The mean clinical follow-up was 29±18 months. The mean transvalvular gradient significantly increased at follow-up in the non-AC group within the global cohort (P=0.003), whereas it remained stable over time in the AC group (P=0.323). The incidence of VHD was significantly lower in the AC group (0.6%) compared with the non-AC group (3.7%, P<0.001), and these significant differences remained within the propensity-matched populations (0.6% vs 3.9% in the AC and non-AC groups, respectively, P<0.001). The occurrence of VHD did not associate with an increased risk of all-cause death (P=0.468), cardiovascular death (P=0.539) or stroke (P=0.170) at follow-up.ConclusionsThe lack of anticoagulation therapy post-TAVR was associated with significant increments in transvalvular gradients and a greater risk of VHD. VHD was subclinical in most cases and did not associate with major adverse clinical events. Future randomised trials are needed to determine if systematic anticoagulation therapy post-TAVR would reduce the incidence of VHD.

Abstract Background About 40% of patients undergoing transcatheter aortic valve replacement (TAVR) have a history of atrial fibrillation (AF) and an additional 10% develop AF after TAVR. However, there is paucity of data regarding the optimal antithrombotic regimen following TAVR in patients with a clinical indication for oral anticoagulants (OAC). Purpose To compare the prognostic impact of OAC plus at least one antiplatelet agent (APT) versus OAC therapy alone in patients undergoing TAVR. Methods We systematically searched the literature for studies evaluating the comparative efficacy and safety of OAC + APT versus OAC alone in TAVR. Random-effect meta-analysis was performed comparing clinical outcomes between the two groups. All-cause mortality and cardiovascular mortality were the efficacy outcomes. Stroke and major bleeding, defined as Bleeding Academic Research Consortium bleeding types 3 to 5, constituted the safety outcome. Results Overall, 398 titles and abstracts were identified through database searching. Four observational studies were selected, for a total of 1929 patients. After a median follow-up of 18.5 months (IQR 11.3–29.3), OAC + APT increased major bleeding events compared to OAC alone (OR=1.79; 95% CI 1.21–2.66; P=0.004) with no difference in stroke (OR 01.02; 95% CI 0.52–2.01; P=0.95), all-cause mortality (OR=1.07; 95% CI 0.78–1.47; P=0.66) and cardiovascular mortality (OR=1.08; 95% CI 0.79–1.47; P=0.62). Conclusion A combination strategy of OAC + APT provides increased risk of bleeding compared to OAC therapy alone in patients undergoing TAVR with similar outcomes in terms of stroke, all-cause mortality and cardiovascular mortality; therefore, when feasible, it should be advised not to add APT on top of OAC therapy in patients without other clinical indications for APT treatment.

Background Some concerns remain regarding the safety of transcarotid and transsubclavian approaches for transcatheter aortic valve replacement. We aimed to compare the risk of 30‐day complications and death in transcarotid/transsubclavian versus transfemoral transcatheter aortic valve replacement recipients. Methods and Results Data from 20 studies, including 79 426 patients (16 studies) and 3992 patients (4 studies) for the evaluation of the unadjusted and adjusted impact of the arterial approach were sourced, respectively. The use of a transcarotid/transsubclavian approach was associated with an increased risk of stroke when using unadjusted data (risk ratio [RR], 2.28; 95% CI, 1.90–2.72) as well as adjusted data (odds ratio [OR], 1.53; 95% CI, 1.05–2.22). The pooled results deriving from unadjusted data showed an increased risk of 30‐day death (RR, 1.46; 95% CI, 1.22–1.74) and bleeding (RR, 1.53; 95% CI, 1.18–1.97) in patients receiving transcatheter aortic valve replacement through a transcarotid/transsubclavian access (compared with the transfemoral group), but the associations between the arterial access and death (OR, 1.22; 95% CI, 0.89–1.69), bleeding (OR, 1.05; 95% CI, 0.68–1.61) were no longer significant when using adjusted data. No significant effect of the arterial access on vascular complication was observed in unadjusted (RR, 0.84; 95% CI, 0.66–1.06) and adjusted (OR, 0.79; 95% CI, 0.53–1.17) analyses. Conclusions Transcarotid and transsubclavian approaches for transcatheter aortic valve replacement were associated with an increased risk of stroke compared with the transfemoral approach. However, these nonfemoral arterial alternative accesses were not associated with an increased risk of 30‐day death, bleeding, or vascular complication when taking into account the confounding factors.

Abstract Background Patients with severe aortic stenosis (AS) and concomitant active cancer (AC) are considered high-risk patients and usually are not allowed to undergo surgical valve replacement. Transcatheter aortic valve replacement (TAVR) may be an attractive option for them; however, little is known about the outcomes of TAVR in this subset of complex patients. Methods and results In this meta-analysis, Medline, Cochrane Library and Scopus databases were searched (anytime up to April 2019) for studies evaluating the outcomes of TAVR in patients with or without AC. We assessed pooled estimates (with their 95% confidence intervals [CIs]) of the risk ratio (RR) for the all-cause mortality at the 30-day and 1-year follow-ups, a 4-point safety outcome (any bleeding, stroke, need for a pacemaker and acute kidney injury) and a 2-point efficacy outcome (device success and residual mean gradient [mean difference]). Three studies (5162 patients) were included. Of those patients, a total of 368 patients (7.1%) had AC. Apart from a significantly higher need for a postprocedural pacemaker (RR 1.29, 95% CI: 1.06–1.58, P=0.01), TAVR in AC patients resulted in similar outcomes for safety and efficacy at the 30-day follow-up compared to those without AC. Patients with AC experienced similar rates of the all-cause mortality at the 30-day follow-up compared to those without (RR 0.92, 95% CI: 0.53 to 1.59, P=0.76); however, the all-cause mortality was significantly higher in patients with AC at the 1-year follow-up (RR 1.71, 95% CI: 1.26 to 2.33, P=0.0006). This mortality difference was independent of cancer stage (advanced or limited) at the 30-day follow-up but not at the 1-year follow-up; only patients with limited cancer stages showed similar all-cause mortality rates compared to those without cancer at the 1-year follow-up (RR 1.22, 95% CI: 0.79 to 1.91, P=0.37). Conclusion TAVR in patients with AC is associated with similar 30-day and potentially worse 1-year outcomes compared to those in patients without AC. The 1-year all-cause mortality appears to be dependent on the cancer stage. Involving a specialized oncologist who usually considers cancer stage in the decision-making process and applying additional preoperative scores such as frailty indices might refine the risk assessment process among these patients.
