ABSTRACT
BACKGROUND: Complex coronary artery disease frequently coexists with severe aortic stenosis. The prognostic impact of complete revascularization (CR) versus incomplete revascularization (IR) in patients undergoing complex and/or high-risk indicated percutaneous coronary intervention (CHIP) and transcatheter aortic valve implantation (TAVI) remains unclear.
METHODS: We analyzed 550 patients who underwent CHIP and transfemoral TAVI between 2013 and 2023 at 14 international centers. Patients were stratified by completeness of revascularization. The primary endpoint was a composite of all-cause death and unplanned cardiovascular (CV) hospitalization at 1 year.
RESULTS: CR was achieved in 299 patients (54.4%). Patients with IR more frequently had three-vessel disease, bifurcation lesions, left main disease, and need for mechanical support. Balloon-expandable valves were more frequently implanted in the CR cohort. Short-term outcomes were similar in the two groups. At 1 year, the incidence of the primary endpoint did not differ significantly between CR and IR groups (20.1 vs. 27.3%, hazard ratio [HR] 0.72, 95% confidence interval [CI] 0.49-1.07). CV rehospitalizations were significantly reduced in the CR group (14.8 vs. 22.8%, HR 0.61, 95% CI 0.38-0.97) even after multivariable adjustment and excluding hospitalizations for repeat revascularization.
CONCLUSIONS: In patients undergoing CHIP and TAVI, CR was associated with a reduction in CV hospitalizations. Further studies are needed to confirm this finding.
