Single or dual antiplatelet therapy after transcatheter aortic valve replacement: an updated systemic review and meta-analysis

Abstract Background The performance of transcatheter aortic valve replacement (TAVR) has expanded considerably during the past decade. Technological advances and refinement in implantation techniques have resulted in improved procedural outcomes, whereas indications are progressively extending toward lower-risk patients. Ischemic/embolic complications and major bleeding remain important and strongly correlate to mortality. In this regard, the optimal antithrombotic regimen after successful transcatheter aortic valve replacement remains unclear. Purpose To compare the efficacy and safety of single antiplatelet therapy (SAPT) versus dual antiplatelet therapy (DAPT) for post Transcatheter Aortic Valve Replacement. Search strategy Key Terms: transcatheter aortic valve replacement, transcatheter aortic valve implantation, antiplatelet, single antiplatelet therapy, dual antiplatelet therapy. Selection criteria Four randomized, controlled clinical trials comparing single antiplatelet therapy versus dual antiplatelet therapy for post TAVR patients were included in this study. Method Extensive search of PubMed, Medline, Cochrane and Ovid was done for articles published until November 20, 2020. Studies were limited to RCTs comparing SAPT and DAPT among patients who underwent TAVR. Outcome measures include: stroke, myocardial infarction, all-cause mortality and major bleeding. Two reviewers independently reviewed the studies. Results were gathered from published articles, journals and clinical trials. Studies were critically appraised with regards to methods of minimizing bias. All four studies included received a quality scale for meta-analysis overall score of not less than B. Statistical analysis was done using Review manager V5.4. Main results Four RCTs with 1086 patients were included in this meta-analysis. Overall, the risk of stroke (OR 0.94 [0.54 −1.64]), myocardial infarction (OR 0.50 [0.18–1.40]), and overall mortality (OR 1.01 [0.65–1.57]) did not differ significantly between DAPT and SAPT. There was noted increased risk of bleeding noted with DAPT, thus favoring SAPT (OR 0.44 [0.30–0.65]). Author's conclusions Among patients who underwent TAVR, DAPT compared to SAPT had similar rates of stroke, myocardial infarction and death. Due to lower rates of bleeding, we recommend using single antiplatelet therapy after TAVR. FUNDunding Acknowledgement Type of funding sources: None.

Life Threatening

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. Clinical trial registration number PROSPERO (International Prospective Register of Systematic Reviews, CRD42018111163).
