Percutaneous Coronary Intervention before or after Transcatheter Aortic Valve Replacement: A Systematic Review and Meta-Analysis Involving 1531 Patients

Le résumé fourni par la source

Background: The optimal timing to perform percutaneous coronary interventions (PCIs) in patients undergoing transcatheter aortic valve replacement (TAVR) is not well established. In this meta-analysis, we aimed to compare the outcomes of patients undergoing PCI before versus after TAVR. Methods: A comprehensive literature search was performed including Medline, Embase, and Cochrane electronic databases up to 5 April 2024 for studies that compared PCI before and after TAVR reporting at least one clinical outcome of interest (PROSPERO ID: CRD42023470417). The analyzed outcomes were mortality, stroke, and myocardial infarction (MI) at follow-up. Results: A total of 3 studies involving 1531 patients (pre-TAVR PCI n = 1240; post-TAVR PCI n = 291) were included in this meta-analysis following our inclusion criteria. Mortality was higher in the pre-TAVR PCI group (OR: 2.48; 95% CI: 1.19–5.20; p = 0.02). No differences were found between PCI before and after TAVR for the risk of stroke (OR: 3.58; 95% CI: 0.70–18.15; p = 0.12) and MI (OR: 0.66; 95% CI: 0.30–1.42; p = 0.29). Conclusions: This meta-analysis showed in patients with stable CAD undergoing TAVR that PCI after TAVR is associated with lower mortality compared with PCI before TAVR.
