Antithrombotic therapy with or without clopidogrel after transcatheter aortic valve replacement. A meta-analysis of randomized controlled trials
ConclusionsIn patients receiving TAVR, a therapeutic strategy of aspirin or OAC with clopidogrel significantly increases the risk of major bleeding without impact on mortality and ischemic outcomes compared to aspirin or OAC without clopidogrel. The performance of different antithrombotic regimens in terms of long-term clinical outcomes and bioprosthesis valve function requires further investigation.Graphic abstractForest plots from pairwise and network meta-analyses associated with an antithrombotic therapy with or without clopidogrel Risk ratio for all outcomes of interest calculated with the pairwise meta-analysis (left...

Aspirin Alone Versus Dual Antiplatelet Therapy after Transcatheter Aortic Valve Replacement: A Systematic Review and Meta-Analysis
ConclusionsOur systematic review and meta-analysis suggested that aspirin alone could decrease the risk of bleeding and was not associated with higher risk of mortality, stroke or myocardial infarction compared with DAPT.

Sinus of Valsalva Thrombosis Detected on Computed Tomography after Transcatheter Aortic Valve Replacement.
CONCLUSIONS: Cardiac CT after TAVR can detect sinus of Valsalva thrombosis, and attention should be paid to this potential source of subsequent systemic embolization. PMID: 32281322 [PubMed - as supplied by publisher]

Aspirin Versus Aspirin Plus Clopidogrel as Antithrombotic Treatment Following Transcatheter Aortic Valve Replacement With a Balloon-Expandable Valve: The ARTE (Aspirin Versus Aspirin + Clopidogrel Following Transcatheter Aortic Valve Implantation) Randomized Clinical Trial
Conclusions This small trial showed that SAPT (vs. DAPT) tended to reduce the occurrence of major adverse events following TAVR. SAPT reduced the risk for major or life-threatening events while not increasing the risk for MI or stroke. Larger studies are needed to confirm these results. (Aspirin Versus Aspirin + Clopidogrel Following Transcatheter Aortic Valve Implantation: The ARTE Trial [ARTE], NCT01559298; Aspirin Versus Aspirin+Clopidogrel as Antithrombotic Treatment Following TAVI [ARTE], NCT02640794)

Comparison of dual antiplatelet therapy versus oral anticoagulation following transcatheter aortic valve replacement: A retrospective single-center registry analysis.
CONCLUSIONS: OAC after TAVR seems to reduce the risk of clinical valve thrombosis without a statistically significant increase in bleeding complications. PMID: 28497845 [PubMed - as supplied by publisher]

Trial design: Rivaroxaban for the prevention of major cardiovascular events after transcatheter aortic valve replacement: Rationale and design of the GALILEO study
Conclusions GALILEO will test the hypothesis that a rivaroxaban-based antithrombotic strategy reduces the risk of thromboembolic complications post-TAVR with an acceptable risk of bleeding compared with the currently recommended antiplatelet therapy–based strategy in subjects without need of chronic oral anticoagulation.

Dual Versus Single Antiplatelet Therapy in Patients Undergoing Transcatheter Aortic Valve Replacement: A Systematic Review and Meta-analysis
Although dual antiplatelet therapy (DAPT) with clopidogrel and aspirin is a widely accepted strategy in patients undergoing transcatheter aortic valve replacement (TAVR), this approach is not evidence based. We therefore sought to systematically review the current evidence for this practice in terms of 30-day outcome looking at stroke, MI, bleeding, and death.
