Background: The optimal access route in patients with severe peripheral artery disease (PAD) undergoing transcatheter aortic valve replacement (TAVR) remains undetermined. Objectives: This study sought to compare clinical outcomes with transfemoral access (TFA), transthoracic access (TTA), and nonthoracic transalternative access (TAA) in TAVR patients with severe PAD. Methods: Patients with PAD and hostile femoral access (TFA impossible, or possible only after percutaneous treatment) undergoing TAVR at 28 international centers were included in this registry. The primary endpoint was the propensity-adjusted risk of 30-day major adverse events (MAE) defined as the composite of all-cause mortality, stroke/transient ischemic attack (TIA), or main access site–related Valve Academic Research Consortium 3 major vascular complications. Outcomes were also stratified according to the severity of PAD using a novel risk score (Hostile score). Results: Among the 1,707 patients included in the registry, 518 (30.3%) underwent TAVR with TFA after percutaneous treatment, 642 (37.6%) with TTA, and 547 (32.0%) with TAA (mostly transaxillary). Compared with TTA, both TFA (adjusted HR: 0.58; 95% CI: 0.45-0.75) and TAA (adjusted HR: 0.60; 95% CI: 0.47-0.78) were associated with lower 30-day rates of MAE, driven by fewer access site–related complications. Composite risks at 1 year were also lower with TFA and TAA compared with TTA. TFA compared with TAA was associated with lower 1-year risk of stroke/TIA (adjusted HR: 0.49; 95% CI: 0.24-0.98), a finding confined to patients with low Hostile scores (Pinteraction = 0.049). Conclusions: Among patients with PAD undergoing TAVR, both TFA and TAA were associated with lower 30-day and 1-year rates of MAE compared with TTA, but 1-year stroke/TIA rates were higher with TAA compared with TFA.

Background—Chronic liver disease is a known risk factor for perioperative morbidity and mortality in patients undergoing cardiac surgery. Very little data exist about such patients treated with transcatheter aortic valve replacement (TAVR). Our objective was to evaluate early and late clinical outcomes in a large cohort of patients with liver disease undergoing TAVR and to determine predictive factors of mortality among these patients. Methods and Results—This multicenter study collected data from 114 patients with chronic liver disease who underwent TAVR in 12 institutions. Perioperative and long-term outcomes were compared with a cohort of 1118 patients without liver disease after a propensity score–matching analysis (114 matched pairs). In-hospital mortality and vascular and bleeding complications were similar between matched groups. Acute kidney injury was more common in liver disease group (30.8% versus 13.5%; P=0.010). Although cardiovascular mortality was similar between groups (9.4% versus 6.5%; P=0.433) at 2-year follow-up, noncardiac mortality was higher in the liver group (26.4% versus 14.8%; P=0.034). Lower glomerular filtration rate (hazard ratio, 1.10, for each decrease of 5 mL/min in estimated glomerular filtration rate; 95% confidence interval, 1.03–1.17; P=0.005) and Child-Pugh class B or C (hazard ratio, 3.11; 95% confidence interval, 1.47–6.56; P=0.003) were the predictors of mortality in patients with chronic liver disease, with a mortality rate of 83.2% at 2-year follow-up in patients with both factors (estimated glomerular filtration rate
