Clinical Outcomes and Factors Associated with MACCE in Chinese Patients Undergoing Single-Hospitalization PCI and Transfemoral TAVR

Background: The incidence and predictors of major adverse cardiovascular and cerebrovascular events (MACCE) in patients undergoing percutaneous coronary intervention (PCI) and transcatheter aortic valve replacement (TAVR) during the same hospitalization remain poorly characterized, particularly in Asian populations. Methods: This single-center retrospective study included 164 consecutive patients who underwent PCI and transfemoral TAVR during the same hospitalization at Beijing Anzhen Hospital between June 2018 and October 2023. The primary objective was to evaluate the incidence of MACCE, and logistic regression analyses were used to identify its predictors. Results: Among 164 patients, the mean age was 73.9 ± 7.2 years, and 57.9% were male. Device success was 97.6% and procedural success was 89.6%. MACCE occurred in 28 patients (17.1%) within the index hospitalization or 30 days after discharge. Independent predictors of MACCE were lower baseline left ventricular ejection fraction (LVEF; OR = 0.955, 95% CI 0.920–0.992; p = 0.017) and mixed aortic stenosis and regurgitation (AS + AR; OR = 6.360, 95% CI 1.035–38.993; p = 0.038). Conclusions: A single-hospitalization PCI and TAVR strategy appeared feasible and was associated with acceptable short-term clinical outcomes in carefully selected Chinese candidates, with lower baseline LVEF and mixed AS and AR as independent predictors of MACCE. The observed clinical outcomes should be interpreted descriptively because of the lack of a contemporaneous comparator group; large-scale prospective studies are needed to further evaluate the safety and clinical benefit of this “one-stop” paradigm.
