Background: Data reflecting the benefit of procedural improvements in real-world transcatheter aortic valve implantation (TAVI) practice are sparse. Aims: To compare outcomes and trends of two TAVI eras from real Italian practice. Methods: A total of 1811 and 2939 TAVI patients enrolled in the national, prospective OBSERVANT and OBSERVANT II studies in 2010–2012 and 2016–2018, respectively, were compared in a cohort study. Outcomes were adjusted using inverse propensity of treatment weighting and propensity score matching. Results: The median age (83.0 (79.0–86.0) vs. 83.0 (79.0–86.0)) and EuroSCORE II (5.2 (3.2–7.7) vs. 5.1 (3.1–8.1)) of OBSERVANT and OBSERVANT II patients were similar. At 1 year, patients of the OBSERVANT II study had a significantly lower risk of all-cause death (10.6% vs. 16.3%, Hazard Ratio (HR) 0.63 (95% Confidence Interval (CI) 0.52–0.76)) and rehospitalization for heart failure (HF) (14.3% vs. 19.5%, Sub-distribution HR 0.71 (95%CI 0.60–0.84)), whereas rates of stroke (3.1% vs. 3.6%) and permanent pacemaker implantation (PPI) (16.6% vs. 18.0%) were comparable between study groups. Conclusions: Age and risk profile among patients undergoing TAVI in Italy remained substantially unchanged between the 2010–2012 and 2016–2018 time periods. After adjustment, patients undergoing TAVI in the most recent era had lower risk of all-cause death and rehospitalization for HF at 1 year, whereas rates of stroke and PPI did not differ significantly.

Background/Objectives: To date, data regarding the characteristics and management of obstructive, stable coronary artery disease (CAD) encountered in patients undergoing transcatheter aortic valve implantation (TAVI) are sparse. The aim of the study was to analyze granular details, treatment, and outcomes of patients undergoing TAVI with obstructive, stable CAD from real-world practice. Methods: REVASC-TAVI (Management of myocardial REVASCularization in patients undergoing Transcatheter Aortic Valve Implantation with coronary artery disease) is an investigator-initiated, multicenter registry, which collected data from patients undergoing TAVI with obstructive stable CAD found during the pre-TAVI work-up. Results: A total of 2025 patients from 30 centers worldwide with complete follow-up were included in the registry. Most patients had single-vessel CAD (56.1%). An involvement of proximal coronary tracts was detected in 62.5% of cases, with 12.0% of patients having CAD in left main (LM). Most patients received percutaneous coronary intervention (PCI) (n = 1617, 79.9%), especially those with proximal CAD (90.4%). At 2 years, the rates of all-cause death [Kaplan–Meier (KM) estimates 20.1% vs. 18.8%, p_log-rank = 0.86] and of the composite of all-cause death, stroke, myocardial infarction, and rehospitalization for heart failure (KM estimates 29.7% vs. 27.5%, p_log-rank = 0.82) did not differ between patients undergoing PCI and those who were not. Conclusions: Patients undergoing TAVI with obstructive CAD more commonly had a single-vessel disease and an involvement of proximal coronary tracts. They were commonly treated with PCI, with similar outcomes compared to those treated conservatively.

BACKGROUND: The best management of coronary artery disease in patients with severe aortic stenosis undergoing transcatheter aortic valve implantation (TAVI) is debated. We investigated the clinical impact of the residual extent of myocardium at risk in patients undergoing TAVI. METHODS: Patients enrolled in the REVASC-TAVI (Management of Myocardial Revascularization in Patients Undergoing TAVI With Coronary Artery Disease) international multicenter registry were stratified according to the myocardium jeopardized by coronary artery disease using the British Cardiovascular Intervention Society Jeopardy Score (BCIS-JS) after a planned coronary revascularization. A planned revascularization included percutaneous coronary interventions performed before TAVI, during TAVI, or within 1 month after TAVI. The study population was divided according to the residual BCIS-JS (rBCIS-JS): patients with extensive residual myocardial at risk (rBCIS-JS >4 group) and patients without extensive residual myocardial at risk (rBCIS-JS ≤4 group). The primary study end point was the composite of all-cause death, nonfatal myocardial infarction, nonfatal stroke, and rehospitalization for heart failure at 2 years. RESULTS: Among the 2407 patients enrolled, 294 pairs of patients were selected by propensity matching and compared. At 2-year follow-up, the incidence of the primary end point was higher in patients with rBCIS-JS >4 compared with patients with rBCIS-JS ≤4 (37.5% versus 23.0%, P =0.004). A significantly lower rate of myocardial infarction was reported in patients with BCIS-JS ≤4 (8.2% versus 2.6%, P =0.011). At multivariate analysis, rBCIS-JS >4 (hazard ratio, 1.43 [95% CI, 1.11–1.84]; P =0.005) independently predicted 2-year major adverse cardiac and cerebrovascular events. CONCLUSIONS: In patients with concomitant coronary artery disease and severe aortic stenosis, the residual myocardial risk significantly affects TAVI outcomes. In particular, a rBCIS-JS >4 is associated with higher rates of major adverse cardiac and cerebrovascular events at 2 years.
