The Early neo2 Registry: Transcatheter Aortic Valve Implantation With ACURATE neo2 in a European Population.

ABSTRACT: Background ACURATE neo2 is a transcatheter aortic valve implantation system consisting of a self-expanding bioprosthetic valve with supra-annular leaflet position and featuring innovations to facilitate placement accuracy and reduce paravalvular regurgitation. Methods and Results The goal of the Early neo2 (Early neo2 Registry of the ACURATE neo2 TAVI Prosthesis) was to gather real-life data on safety and efficacy in a European transcatheter aortic valve implantation population treated with ACURATE neo2. Data were collected from 554 consecutive patients treated with ACURATE neo2 at 12 European sites (mean age, 82 years; 66% women; mean European System for Cardiac Operative Risk Evaluation II, 4.5%±3.8%) between September 2020 and March 2021. The composite primary end point was the occurrence of any of the following: postoperative (in-hospital) paravalvular regurgitation grade ≥2, in-hospital acute kidney injury stage 3, postoperative pacemaker implantation, 30-day death, and 30-day stroke. The primary end point occurred in 12.6% of patients. The 30-day rates for all-cause death and all stroke were 1.3% and 2.7%, respectively, and 1.5% of patients exhibited stage 3 acute kidney injury. A total of 34 patients (6.2%) received a postoperative permanent pacemaker. Per core laboratory-adjudicated echocardiographic analysis, mean postoperative aortic valve gradient was 7.6±3.3 mm Hg, and 2.8% of patients exhibited paravalvular regurgitation grade ≥2. Conclusions In this report of postmarket use of the ACURATE neo2 valve in a real-world transcatheter aortic valve implantation population, patients exhibited favorable postoperative hemodynamics and clinical outcomes and a low rate of postoperative pacemaker implantation.

Project description:BackgroundCoronary access after transcatheter aortic valve implantation (TAVI) with supra-annular self-expandable valves may be challenging or un-feasible. There is little data concerning coronary access following transcatheter aortic valve-in-valve implantation (ViV-TAVI) for degenerated surgical bioprosthesis.AimsTo evaluate the feasibility and challenge of coronary access after ViV-TAVI with the supra-annular self-expandable ACURATE neo valve.Materials and methodsSixteen patients underwent ViV-TAVI with the ACURATE neo valve. Post-procedural computed tomography (CT) was used to create 3D-printed life-sized patient-specific models for bench-testing of coronary cannulation. Primary endpoint was feasibility of diagnostic angiography and PCI. Secondary endpoints included incidence of challenging cannulation for both diagnostic catheters (DC) and guiding catheters (GC). The association between challenging cannulations with aortic and transcatheter/surgical valve geometry was evaluated using pre and post-procedural CT scans.ResultsDiagnostic angiography and PCI were feasible for 97 and 95% of models respectively. All non-feasible procedures occurred in ostia that underwent prophylactic "chimney" stenting. DC cannulation was challenging in 17% of models and was associated with a narrower SoV width (30 vs. 35 mm, p < 0.01), STJ width (28 vs. 32 mm, p < 0.05) and shorter STJ height (15 vs. 17 mm, p < 0.05). GC cannulation was challenging in 23% of models and was associated with narrower STJ width (28 vs. 32 mm, p < 0.05), smaller transcatheter-to-coronary distance (5 vs. 9.2 mm, p < 0.05) and a worse coronary-commissural overlap angle (14.3° vs. 25.6 o , p < 0.01). Advanced techniques to achieve GC cannulation were required in 22/64 (34%) of cases.ConclusionIn this exploratory bench analysis, diagnostic angiography and PCI was feasible in almost all cases following ViV-TAVI with the ACURATE neo valve. Prophylactic coronary stenting, higher implantation, narrower aortic sinus dimensions and commissural misalignment were associated with an increased challenge of coronary cannulation.
