Sumario:Abstract Objectives The aim of the study was to analyze the impact of concomitant coronary artery disease (CAD) assessed by the SYNTAX score (SS) and periprocedural percutaneous coronary intervention (PCI) on outcomes after transcatheter aortic valve replacement (TAVR). Background Due to controversial data regarding the effect of CAD on outcomes after TAVR, proper revascularization strategies remain a matter of debate. Methods 553 patients with severe aortic stenosis undergoing TAVR were included in this study. SS was calculated for each patient at baseline and after PCI. Primary outcome was one-year all-cause mortality. Results 60.2% of patients (N = 333) exhibited CAD with a mean SS of 10.8 ± 8.8. Of those, 120 patients (36.0%) received periprocedural PCI. In the treatment group, mean SS was decreased from 14.9 ± 9.1 to 6.3 ± 6.7. Patients with concomitant CAD suffered more frequently from myocardial infarction (MI) post TAVR compared to those without CAD (2.1% vs. 0.0%; P < 0.01). In the CAD cohort, MI rates were comparable between patients with and without PCI (2.2% vs. 2.5%; P = 0.71). Regarding SS, patients with a residual SS < 8 showed significant lower rates of one-year mortality (9.0% vs. 18.2%; P = 0.016) and MACCE (16.5% vs. 32.2%; P = 0.001). Besides left bundle brunch, predictors for an increased one-year mortality were a residual SS ≥ 8 in the CAD group (OR = 3.17; P = 0.011) and a EuroSCORE ≥ 4% in the entire study population (OR = 2.18; P = 0.017). Conclusion Our results suggest that a residual SS-guided revascularization strategy may improve prognosis after TAVR in patients with concomitant CAD. PCI aiming for a residual SS < 8 was associated with improved one-year clinical outcomes.
