Background: Acute ischemic stroke remains a serious complication of transcatheter aortic valve replacement (TAVR). Cerebral embolic protection devices (CEPD) were developed to mitigate the risk of acute ischemic stroke complicating TAVR (AISCT). However, the existing body of evidence does not clearly support CEPD efficacy in AISCT prevention., Objectives: In a cohort of patients with AISCT, we aimed to compare the characteristics and outcomes of patients who have had unprotected TAVR (CEPD-) vs CEPD-protected TAVR (CEPD+)., Methods: Data were derived from an international multicenter registry focusing on AISCT. We included all patients who experienced ischemic stroke within 72 hours of TAVR. Stroke severity was assessed using the National Institutes of Health Stroke Scale (NIHSS). Primary outcomes were neurologic disability status according to the modified Rankin Score at 30 days, and 6-month all-cause death. Propensity score matched analysis was used to control for differences between groups., Results: In 18,725 TAVR procedures, 416 AISCT (2.2%) within 72 hours were documented, of which 376 were in the CEPD- TAVR group and 40 in the CEPD+ TAVR group. Although the middle cerebral artery stroke rate was similar in both groups (29.7% CEPD- vs 33.3% CEPD+; P = 0.71), AISCT in the CEPD+ group was characterized by a lower rate of internal carotid artery occlusion (0% vs 4.7%) and higher rate of vertebrobasilar system strokes (15.4% vs 5.7%; P = 0.04). AISCT was severe (NIHSS ≥15) in 21.6% CEPD- and 23.3% CEPD+ AISCT (P = 0.20). Disabling stroke rates (modified Rankin Score >1 at 30 days) were 47.3% vs 42.5% (P = 0.62), and 6-month mortality was 31.3% vs 23.3% (P = 0.61), in the CEPD- and CEPD+ groups, respectively. In the propensity score matched cohort, disabling stroke rates were 56.5% vs 41.6% (P = 0.16), and 6-month mortality was 33% vs 19.5% (P = 0.35), in the CEPD- and CEPD+ groups, respectively., Conclusions: In a large cohort of patients with AISCT, the use of CEPD had little effect on stroke distribution, severity, and outcomes., Competing Interests: Funding Support and Author Disclosures Dr Seiffert has received speaker or advisory fees from Abbott Vascular, Abiomed, Amgen, AstraZeneca, Boston Scientific, Bristol Myers Squibb, Daiichi-Sankyo, Edwards Lifesciences, Inari Medical, Medtronic, Pfizer, Shockwave Medical, and Siemens Healthineers; and a research grant from Boston Scientific—all unrelated to the submitted work.

Objectives: The authors sought to evaluate the incidence, predictors, and outcomes of new permanent pacemaker implantation (PPI) after transcatheter aortic valve replacement (TAVR) with contemporary self-expanding valves (SEV)., Background: Need for PPI is frequent post-TAVR, but conflicting data exist on new-generation SEV and on the prognostic impact of PPI., Methods: This study included 3,211 patients enrolled in the multicenter NEOPRO (A Multicenter Comparison of Acurate NEO Versus Evolut PRO Transcatheter Heart Valves) and NEOPRO-2 (A Multicenter Comparison of ACURATE NEO2 Versus Evolut PRO/PRO+ Transcatheter Heart Valves 2) registries (January 2012 to December 2021) who underwent transfemoral TAVR with SEV. Implanted transcatheter heart valves (THV) were Acurate neo (n = 1,090), Acurate neo2 (n = 665), Evolut PRO (n = 1,312), and Evolut PRO+ (n = 144). Incidence and predictors of new PPI and 1-year outcomes were evaluated., Results: New PPI was needed in 362 patients (11.3%) within 30 days after TAVR (8.8%, 7.7%, 15.2%, and 10.4%, respectively, after Acurate neo, Acurate neo2, Evolut PRO, and Evolut PRO+). Independent predictors of new PPI were Society of Thoracic Surgeons Predicted Risk of Mortality score, baseline right bundle branch block and depth of THV implantation, both in patients treated with Acurate neo/neo2 and in those treated with Evolut PRO/PRO+. Predischarge reduction in ejection fraction (EF) was more frequent in patients requiring PPI (P = 0.014). New PPI was associated with higher 1-year mortality (16.9% vs 10.8%; adjusted HR: 1.66; 95% CI: 1.13-2.43; P = 0.010), particularly in patients with baseline EF <40% (P for interaction = 0.049)., Conclusions: New PPI was frequently needed after TAVR with SEV (11.3%) and was associated with higher 1-year mortality, particularly in patients with EF <40%. Baseline right bundle branch block and depth of THV implantation independently predicted the need of PPI., Competing Interests: Funding Support and Author Disclosures Dr Pagnesi has received personal fees from Abbott, AstraZeneca, Boehringer Ingelheim, and Vifor Pharma.

Background: Despite advances in transcatheter aortic valve replacement (TAVR), periprocedural acute ischemic stroke remains a concern., Objectives: The aims of this study were to investigate acute ischemic stroke complicating TAVR (AISCT) and to describe the indications and outcomes of interventions to treat AISCT., Methods: An international multicenter registry was established focusing on AISCT within 30 days of TAVR. Stroke severity was assessed using the National Institutes of Health Stroke Scale. Primary outcomes were 1-year all-cause death and neurologic disability status at 90 days according to modified Rankin scale score., Results: Of 16,615 TAVR procedures, 387 patients with AISCT were included (2.3%). Rates of 1-year death were 28.9%, 35.9%, and 77.5% in patients with mild, moderate, and severe stroke, respectively (P < 0.001). Although 348 patients were managed conservatively, 39 patients (10.1%) underwent neurointervention (NI) with either mechanical thrombectomy (n = 26) or thrombolytic therapy (n = 13). In a subanalysis excluding patients with mild stroke, there was no clear 1-year survival benefit for NI compared with conservative management (47.6% vs 41.1%, respectively; P = 0.78). In a logistic regression model controlling for stroke severity, NI was associated with 2.9-fold odds (95% CI: 1.2-7.0; P = 0.016) of independent survival at 90 days., Conclusions: AISCT carries significant morbidity and mortality, which is correlated with stroke severity. The present findings suggest that neurologic disability for patients with moderate or worse stroke could potentially be improved by timely intervention and highlight the importance of collaboration between cardiologists and neurologists to optimize AISCT outcomes., Competing Interests: Funding Support and Author Disclosures Dr Pilgrim has received research grants to the institution from Edwards Lifesciences, Boston Scientific, and Biotronik; has received personal fees from Biotronik and Boston Scientific; has received other compensation from HighLife SAS and Medira; and is a proctor for Medtronic.

Valve-in-valve transcatheter aortic valve replacement (VIV-TAVR) provides a safe and effective treatment option for failing surgical aortic bioprostheses. Self-expanding supra-annular valves offer optimal haemodynamics for this clinical application. The Acurate Neo transcatheter heart valve (THV) offers further unique advantages with stabilisation arches to assist with alignment, upper crowns to restrain bioprosthetic valve leaflets, rapid final opening coaxial to the left ventricular outflow tract and an open design that optimises future coronary access. We report our procedural technique and experience using the Acurate Neo THV in four VIV-TAVR implantations for patients aged between 70 and 81 yrs. All patients presented with severe symptomatic valvular aortic regurgitation (AR), one of whom was in cardiogenic shock. The patients had malfunctioning surgical bioprostheses (stented n = 3; stentless n = 1) ranging in size from 21 to 25 mm. The Acurate Neo THV was successfully implanted in all patients without any complications, residual AR, coronary compromise or need for permanent pacing. Length of stay was 2 to 7 days. Follow-up to 12 months revealed no adverse events. The Acurate Neo THV is an attractive self-expanding option for patients with AR due to degeneration of a surgical aortic valve bioprosthesis., Competing Interests: Declaration of competing interest David Hildick-Smith and James Cockburn are proctors for Boston Scientific., (Copyright © 2020 Elsevier Inc.
