OBJECTIVES: This study sought to determine if percutaneous coronary intervention (PCI) prior to transcatheter aortic valve replacement (TAVR) in patients with significant coronary artery disease would produce noninferior clinical results when compared with no PCI (control arm).
BACKGROUND: PCI in patients undergoing TAVR is not without risk, and there are no randomized data to inform clinical practice.
METHODS: Patients with severe symptomatic aortic stenosis and significant coronary artery disease with Canadian Cardiovascular Society class ≤2 angina were randomly assigned to receive PCI or no PCI prior to TAVR. The primary endpoint was a composite of all-cause death or rehospitalization at 1 year. Noninferiority testing (prespecified margin of 7.5%) was performed in the intention-to-treat population.
RESULTS: At 17 centers, 235 patients underwent randomization. At 1 year, the primary composite endpoint occurred in 48 (41.5%) of the PCI arm and 47 (44.0%) of the no-PCI arm. The requirement for noninferiority was not met (difference: -2.5%; 1-sided upper 95% confidence limit: 8.5%; 1-sided noninferiority test P = 0.067). On analysis of the as-treated population, the difference was -3.7% (1-sided upper 95% confidence limit: 7.5%; P = 0.050). Mortality was 16 (13.4%) in the PCI arm and 14 (12.1%) in the no-PCI arm. At 1 year, there was no evidence of a difference in the rates of stroke, myocardial infarction, or acute kidney injury, with higher rates of any bleed in the PCI arm (P = 0.021).
CONCLUSIONS: Observed rates of death and rehospitalization at 1 year were similar between PCI and no PCI prior to TAVR; however, the noninferiority margin was not met, and PCI resulted in a higher incidence of bleeding.
